what are trophic levels?Give an example of a food chain and State the different trophic levels in it.
Answers
Answer:
The trophic level of an organism is the position it occupies in a food web. A food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. The trophic level of an organism is the number of steps it is from the start of the chain.
food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected. eg: A hawk might also eat a mouse, a squirrel, a frog or some other animal.
Explanation:
Level 1: Plants and algae make their own food and are called producers. Level 2: Herbivores eat plants and are called primary consumers. Level 3: Carnivores that eat herbivores are called secondary consumers. Level 4: Carnivores that eat other carnivores are called tertiary consumers.
Answer:
The first trophic level includes herbivores like a cow, goat, etc. - The second trophic level includes carnivores like a tiger, lion, etc. - The tertiary trophic level includes omnivores like humans, bears, etc. - The trophic level of an organism is the position that it occupies in a food web.
