In any food chain there will be...?

None of these answers are correct for all food chains.  "D" would seem to be the best answer, but it is not always true.  It always depends on the ecosystem.  In most cases, producers will outnumber the consumers.  But not always.  For example, in a forest ecosystem a single large producer (oak tree or whatever) may support thousands of caterpillar and hundreds of  consumers like spiders and birds. If you have to pick one, pick D. Just know that it is not always true.

people (you, me, everyone), plants, animals, or anything on this world that can grew.

In sea algae are the primary producers in the marine Food Chain.To start an ecosystem or biome primary producers are main requirement.So,you are right!

You can eat any animal in the whole wide world. Unless their meat is deadly. isn't a puffer fish deadly?? I can't remember.

It all depends on humankind. \n\nFirst, about cats and dogs: The best bet would be that cats and dogs will exist as long as humanity lives, maybe a few tens of millions of years longer.\n\nSecond, what will happen next? New clases of animals appear and spread when there is a new type of habitat for them. Either because it is unoccupied (it happened with coming from ocean to land), or because old occupants are dead or less adapted to cope with changed conditions on Earth (that happened with dinosaurs and mammals that took over from them).\n\nRight now, life is more or less everywhere on Earth. So new animals - whatever they will be - will take over from existing mammals and birds only if humankind changes Earth enough, or destroys their competitors.\nChances are that animals able to survive humans (rodents, for example) will be the ancestors of the new classes of animals. \nHowever, if humankind stays on track, WE will create new animals, and choose how they will look like. Alternatively, if humans take animals to other planets where they can survive, there is a chance for new kinds of animals evolving there.

listen to t. h. white (sword in the stone author). we will in the end use up all our resources and the organisms that need them will die. it will break off part of the food chain and no other organisms will be able to live. the part of that is what happened to the dinosaurs (likely) and it will probably happen to humans considering how destructive we are.

Depends on what food.

The food chain or web is a map of the different species and how they depend on each other. In our case for example the bottom of the web would be plants then these link to insects as food source, another links takes us to many species of birds who prey on insects for food and then a link goes to raptor birds at the top of our food chain as they prey on small birds for food.\n\nNow in the family of pesticides is insecticide which could easily end up being an indiscriminate insect management tool.\n\nWhat I mean by indiscriminate is the insecticide can create three problems besides it's intended use.\n\nThe first problem is that while the insecticide will kill it's intended insect it can also kill benign insects as well. This then could impact by eliminating a food source for a species of bird further up the food chain that only eats that insect. Without that food source the bird then might compete with other species of birds to further reduce a food source and both populations of birds have problems.\n\nThe second problem is an insect that is sprayed in insecticide is then eaten by a bird. Now comes the question of what effects the toxic insecticide could have on the bird. It could be toxic as well and so kill the bird, it could be carcinogenic and affect the birds or when they reproduce. Finally it could be a carcinogen but simply stored in the fatty tissue or some place in the bird. Finally at the top of the food chain is the raptor birds. One example to explain the problem here is the Bald Eagle and that by preying on birds with a buildup of insecticide in their bodies absorbed it and then the effect was the insecticide acted on the female eagle and the population started to produce thin shelled eggs that made it impossible to produce offspring.\n\nThe final problem of insecticide is that other habitate food chains exist. One example is lake shore to fish and to lake bottom species. In this case you can have rain wash the insecticide from it's intended location to the lake shore and just as in the birds, a food chain/web is jeopardized.

Not yet. All life WE know is carbon based. Try to find speculation on silicon based life, for a start.

Depends on which chicken and which egg!

Let's see...\nEchinoderms (technically it's not exactly an exoskeleton, but for practical purposes it could do)\nCrustaceans\nMollusks\nsome Annelids\nmm this is making me hungry...

Dead plants and animals cannot be said to occupy a level in the food chain as being dead they are not able to eat and therefore occupy the lowest space on the trophic level  as food for fungus, microbes, insects, animals and other plant life.\n\nStrange question.

No, science cannot feed the world, we are already overpopulated and technology can only take us so far. There will always be starving countries unfortunately. All foods that we eat have been modified, and yes, despite scares genetically modified foods are generally ok.

I believe there are, but they are far and few between. We'll refer to those one's as diamonds. The other more common species we'll refer to as coal, there's lots of that and it's only good for burning =)\n\nGood luck in your search.

Most food will do: cheese, bread, any sort of plant tissue

Nope what about about the lions tigers & bears & even fish kills other animals for food! Think about that.

cattle (cows, pigs, horses, donkeys, poultry), wild boar, different kinds of deer, rabbits, several snakes, certain amphibians, red squirrel, and a whole bunch more.\n\nDefinitely no monkeys.
