box turtle food chain!!!!!
There cannot be too many links in a food chain. Food chains always begin with a plant and end with an animal. If there are more than 4 or 5 links in the chain , there will not be enough food for the animals at the end of the chain.

They're simply called layer 1, 2, 3 and 4. Usually, the biggest individual animal (EG: Bear) is at the top, while the biggest mass of animals (EG: Copepods) is at the bottom.

There are 4 basic levels to a tropical rainforest food chain. They are the primary producers (plants, flowers, fruits, leaves), the primary consumers (frogs, fish, possums, birds), first level carnivores (snakes, platypus, owls), and second level carnivores (crocodiles, pythons, feral dogs and cats).
whales
Because all foods fit in those groups and it may become hard to understand.
some are more than 4 animals. a plant (primary producers) is eaten by a grasshopper (primary consumer) who is eaten by a rat or mouse (secondary consumer) a snake (tertiary consumer) eats the rat and a hawk (quaternary consumer) eats the snake.but most are 4 or less due to the fact that the amount of energy that is transferred from one organism to the next varies in different food chains. Generally, only about ten percentof the energy from one level of a food chain makes it to the next. so if there were many more in the chain they wouldn't get much energy from what they ate.
