Which type of food chain is represented by following example? Dead animals \(\rightarrow\) insect scavenger \(\rightarrow\) Frog \(\rightarrow\) Snake
1 Detritivores food chain
2 Grazing food chain
3 Both a and b
4 Food web
Explanation:
Detritivores food chain starts with dead organic matter which is eaten by animals which in turn are eaten by other animals. A large amount of energy flows through detritus food chain and organic matter is decomposed
