Question

mention the types of organisms found at different trophic levels​

Answer 1

(The arrangement which I'm talking is from bottom to top)

At the first level we find the "Producers", which are plants and algae; they produce their own food.

At the second level we have the "Primary consumers" which are Herbivores and consume plants and algae.Eg, Goats, Cows, Rabbits

At the third level we have the "Secondary consumers" which are Carnivores that specifically eat other herbivores.Eg, Foxes which specifically eat Rabbits.

At the fourth level we have the "Tertiary consumers" which are Carnivores and Omnivores that consume producers, primary and secondary consumers.Hawks are a suitable example.

At the last level we the "Apex predators" which are exclusively carnivores and consume other animals.Eg. Tigers, Lions etc.

Answer 2

In present in our ecosystem we have four types of trophic levels which are found till now. This is because level of energy gets decreased as accordance to the flow of energy in other words we can say that when level enters into the next trophic level then there will decrease in the energy.

So four trophic levels are as follows:-

1. First trophic level are Producers.

2. Primary consumers are considered as the primary consumers.

3. While third trophic level are secondary consumers.

4. Fourth and the last trophic level are top consumers.
