how do plants protect themselve from animals?

They produce chemicals that are poisonous/unpleasant tasting (milkweed)\nOr produce chemicals that attract predators of the plant-eating insect\n\nThey grow thorns or spikes or itchy hairs (greenbriar)\n\nThey have a symbiotic relationship with ants who do the protecting (acacia trees)

This is so they ensure the survival of the plant species by reproducing them self's.  The seeds attract birds and animals to eat them and they in turn help spread the seed.  This is more efficient than pure wind distribution.

Plants are covered by the epidermis, which can have a cuticle.  According to this article, the cuticle is essentially wax which makes it waterproof.

If you consider evolution, any animal that is able to protect itself will. They would have only adapted the ability to fight off enemies or hide from them if it was something that they used and it saved their lives. The only "passive" animals out there are the ones who don't have the ability to defend themselves. So to answer your question, no, there are no animals who naturally choose to not protect themselves when they are capable. Only on an individual basis could this happen. There are no known species or populations that do that.\n\nThe sloth is endangered because we cut down its trees that keep it safe. Frogs don't let animals eat them, they try to run away. The closest thing to what you are describing that I can think of would be a mother duck pretending to be injured to lure the predator away from the chicks. Of course, when she gets it away from the chicks, she too flies away.

It doesn't really.  It's pretty harmless to plants.

Well, humans need animals and plants for food, raw materials, entertainment and other related functions.\n\nHumans can help plants disperse their seeds and can help feed certain animals.

Plants use chemical signals to communicate. For example, acacia trees in Africa release chemicals into the air when fed on by giraffes. This alerts the tree and surrounding trees to produce toxins in the leaves which eventually deter the giraffe from feeding too much on the one tree. So technically you could talk to your plants by using chemical signals. Animals also use chemical signals (pheromones) to communicate.

Birds feed off them as well as many animals, when they die there corses help feed plants and the cycle goes around and around.

Excellent question.  \n\nThis is due to a process called osmosis.  Osmosis is the net movement of water molecules in and out of a partially permeable membrane (a kind of barrier that only allows certain molecules to pass through), from a region of their higher concentration to a region of their lower concentration.\n\nIts pretty self-explanatory here.  Since the concentration of water is higher inside than outside of the plant, water moves out of the plant, resulting in the plant dehydrating and dying.

I dont agree with the first two answers, just because the plants dont get pollinated it doesnt mean they will die, they just will not be able to reproduce. \nIf all animals die, there will be a major disruption in 2 main cycles that could affect the ecology. The Nitrogen cycle, and the CO2 cycle. \n\nPlants use Carbondioxide for photosynthesis and give off oxygen.. where animals use oxygen and give off carbondioxide. any instability in this cycle would have detrimental effects.\n\nNitrogen cycle.. ammonia based compounds in the soil mostly from animal waste are converted into nitrites and nitrates by specific bacteria  so that they are absorbed by the plants...without animals, there would be a major imbalance.

sunlight.\n\nPlants capture energy from sunlight, animals eat plants... or other animals that have eaten plants.\n\nAloha

I'm not clear on what you are asking.  I think you might be asking how cities can save wildlife.  \n\nYou can find different kinds of wildlife in different cities, so there are a variety of rules to protect them.  Some cities protect open green spaces as wildlife habitat, decrease speed limits to prevent animals from being hit by cars, and support wildlife rehabilitators who take care of injured animals.  The best thing that a city can do to help wildlife is practice smart planning to prevent the city from spreading into nearby wildlands.

Their size and the size of the heard is their protection. Other than man they have no real natural predators. Although larger predators will try to pick off a stray calf they are not willing to take on a mother bison protecting her calf.

What level of school?\n\nHumans eat plants, and sometimes animals as food. \n\nPlants are used to provide medicines and materials for construction. \n\nPlants protect the soil from erosion.\n\nPlants make oxygen for humans to breathe. \n\nPlants give us shade and places for animals to live. \n\nAnimals are human companions, and used to be a primary source of power. In some parts of the world, animals are still used for power and transportation. \n\nAnd so on.
