When liions prey on a herd of antelopes, some antelopes are killed and some escape and live to reproduce.?

c is the right answer.\n\nA makes no sense in relation to the question\nB natural selection has a bit of randomness in it of course but is basically not random. I mean, the fastest critter in the herd may have had an unlucky day and so he will not procreate, oops. But otherwise, the slowest are intentionally selected by the lion and that is never random.\nD just isn't true, plenty of proof there.

fireants probably killed them....or you have an anteater on the loose....although i dont know why either one would leave the heads

Depends what kind of animals! Some eat other animals.  Some forage under the snow for food.  Some eat tree bark, etc.  Some get fed by humans.

a. Predators reduce the number of prey, simply because they eat them! But in the long run, evolution allows the prey to compensate by reproducing at a more frequent rate. This is why foxes reproduce much more slowly than do rabbits. Rabbits get eaten a lot by other animals such as foxes, so their survival as a species depends on their numbers.\n\nb. Predators evolve to become more efficient hunters. Over time, they grow sharp teeth, acute senses, speed and stealth.. Prey evolve to be better able to run away or hide from predators. They may become more alert of their senses, develop faster legs, learn to climb trees.. etc.\n\nHope that helps!

I think so. At least at somepoint in their history anyway - they will have had predators, or illnesses that they could not fight, and so the fittest or more suited to survival will have survived, and the 'weaker' will have perished. It could be argued that if they are advanced then natural selection would apply less. For example humans don't really have any predators, and through medical intervention we can stop many ailments that would otherwise kill us: If a lion was born with an inherited disease which affected their mobility then they wouldn't survive for very long in the wild, and neither would a neandarthal human, but modern day humans could lead a full life with such an ailment.

Good point!\nAs for them being veggi beforehand...LMAO! (I wonder what that fossilized *meat* was, found in a dino's stomach? T-Rex, anyone?)\nIt's not just animals either, it goes right down to the microscopic level. I could point out the fact(scary word for xtians!)that there's more prey than predators too...but I won't. \nNature is cruel to be kind.\n\n:)

Agalychnis callidryas prey on small insects.  I hope that is specific enough.  I could have said things that move.

There are many different kinds of animals in the world in order to survive. Each and every animal has their own habitat and according they consume food. Some are herbivorous and some are carnivorous. The food chain goes on to maintain ecological balance .For instance grass is eaten by grasshopper the later is eaten by a frog and the frog is eaten by a snake which is ultimately eaten by a hwak.

I dont get this question at all. Are you asking if all those people are dying, will wild animals take over?! And if so - why?!

One of the main reasons for adults killing young is due to males taking over leadership of a group. If they wait for young animals to become independent of their mothers, the males may not sire offspring before new males take over the group. Alternatively, if they kill the young, the females often become fertile soon afterwards, so the males are more likely to become fathers. Some dominant animals may eat young animals in order to enforce their dominance over submissive group members. Other animals may eat young in order to satisfy hunger pains or due to psychological stress, due to overcrowded conditions. If there are too many animals in a limited area, the whole group may die out, due to too little food being available. If many of the animals die, the food supply goes further and the survivors can produce young when conditions are ideal. All of these mechanisms may seem cruel, but many of the strategies have a logical basis, as they are geared towards survival of animal groups, rather than the survival of each individual.  \n\nInfanticide has been found in many species, including humans and other primates, cats, dogs, whales, rodents, insects and fish. http://www.ratbehavior.org/infanticide.htm gives the following reasons for infanticide: to gain food; to gain increased access to physical resources like food, nesting sites or space; to avoid caring for unrelated offspring; to bias the sex ratio of the litter. Adult males may kill a female's young to increase his chances of mating. Infanticide may also be due to aggression or to disturbances in the physical or social environment. For example when female voles, mink and other mammals are in a state of psychological stress, they may eat their young. \n\n1.   Many rodents show infanticide, including rats, ground squirrels, lemmings, hamsters, mice, voles, muskrats, gerbils, prairie dogs and marmots. \n2.   Rats and mice: When populations of mice and rats rise rapidly, the hungry and stressed survivors may kill and eat young.  http://www.ratbehavior.org/infanticide.htm goes into detail about infanticide in Norway rats. This is usually directed towards newborn rats. A mother pet rat may eat her own offspring. Mothers tend to kill deformed or wounded infants, which may allow her to allocate resources to the healthy pups, which are more likely to survive. Mothers may also kill litters when they are stressed, perhaps because she perceives the environment as too hostile for pup survival, or if she cannot to rear the litter successfully. She recuperates some her energetic investment by consuming the young. Malnourished mothers, and mothers who have an abnormal birth experience, may also become infanticidal. An unrelated adult male rat may kill young to bring the mother back into oestrus sooner, so he can sire a litter of his own. Maternal aggression after the birth of a litter may reduce infanticide. Unrelated females may kill young rats to gain food and take over the nest. \n3.   Eastern grey squirrels: http://www.blackmouthcur.com/Gray%20Squirrels.htm  states that some males kill the young so that the females re-enter oestrus. http://fwie.fw.vt.edu/TN/TN10056h.htm states that captive, stressed females may kill their young. \n4.   Belding's ground squirrels: When Belding's ground squirrels fail to attend their territories, unrelated females or one-year-old males may arrive and kill pups. Yearling males usually eat the carcasses, so their infanticide may be motivated by hunger. When a predators kill a female's young, the female often emigrates to a new, safer site and kills the young there before she can settle. By removing juvenile females who may remain in the preferred area, infanticidal females educe further competition for a nest site. Mothers with close relatives as neighbours lose fewer young to infanticides than females without neighbouring kin. This is because groups of females detect marauders more quickly and expel them more rapidly than individuals acting al

Female cheetahs are almost always solitary except when being courted or if they have young.  They do not defend territories.  They travel far over vast areas of up to 600 square miles.  Male cheetahs, often in groups of 2 or 3, establish patrol and defend territories of 20-25 square miles.  These territories are somewhat greater in average size in Eastern then in Southern Africa. \n\nMales often remain with females for two days if they are breeding.  If a coalition of males find a female, there may be mild aggression among them (the males may also cause the female some anxiety because they will surround her and check to see if she is in season).  This is nothing compared to fights between coalitions. \n\nAfter a gestation period of 90-95 days, a female gives birth to as many as 9 cubs but seldom more then 3 or 4 survive.  They are born in lairs situated among boulders, tall vegetation, or a marsh. Sadly, the mortality among cubs is very high especially within the first two months of their lives.  Causes of their mortality are predation, grassfires, disease, exposure, and infanticide by male cheetahs.  Of all of these, predation takes the most toll.  Lions, spotted hyenas, jackals, and birds of prey will kill them if they find them.  A mother may be gone for up to 48 hours or more while hunting.  What seems to help them is their natal coat.  It is light gray and wooly on the cub's back and black on its belly. The cubs lose this coat by four months.  Its main function seems to be for camouflage.  I have also read that a very young cheetah almost looks like a honey badger.  Honey badgers are aggressive animals and it is thought that the coloring of a cheetah cub mimics them so that some predators would leave them alone.....Surviving cubs are brought out of their den at 6 to 8 weeks and they accompany their mother from then on.  They are extremely playful with each other during this time.  This helps them practice their hunting skills.  At three months, the mother brings home live prey (usually a baby gazelle) to her cubs.  They further practice their hunting skills by chasing it, etc.  This way, the cubs soon learn to kill for themselves. They leave their mothers at 14 to 18 months but they are still inexperienced hunters.  Because of this, the cubs stay together for about 6 months after leaving their mother.  After this, the females leave to go off on their own and the brothers stay together for life\n\n\nmng.1432@gmail.com

It is written in the scriptures that in heaven that the predator and prey animals will exist together in harmony so I say yes. \n\nOther mammals are not held to the same set of standards that people are held to. There is not sufficient sentience to reach an 'age of accountability'.

Once they've found food, they'll keep coming back. Make sure they can't get into your trash, etc. and they might go away but it's doubtful. You either have to trap them and move them somewhere else or kill them (I hate to say that). We've had the same issue at our lake property. They come and raid our bird feeders at night. The full time residents down there eventually kill them instead of trapping and moving them.

Animals need to eat, wherever they are. If they're at your place you'll feed them, if they're not domesticated and live outside they'll look for food themselves. So whatever you do, animals (and pets) will eat! And I don't think killing them all is a good solution, they're not the reason why some people have nothing to eat ;)

Its not suicide as such, they get attracted to light and do not move from there, and hence making themselves easy prey for humans and animals.\n\nYes, as per an earlier answer it could be confusing of their signals (Electro magnetic signals , which give them direction during migration), or defective genes as said earlier.

A mature White-tail stays in thick cover. Thats why they survive to be mature and big...they are much wiser. Look for them during the peak of the rut. Thats probably your only chance to harvest a big buck. After the rut they go into the cover again.
