(B) Primary carnivore are also known as secondary consumers
(C) The third trophic level is occupied by secondary carnivores
(D) Maximum 3 to 5 trophic levels are possible in a food chain

Secondary carnivores belong to which trophic level in food chain of ecosystem ? 1 T1 2 T2 3 T3 4 T4

Read the following statements. (i) Removal of tigers from an area will result in increased growth of vegetation of that area. (ii) Organisms at each trophic level depend on those at the lower trophic level for their energy demands. (iii) Food chains are sustained by producers and decomposers (iv) In a food chain , some organism like sparrow operates at one trophic level only. Select an option which shows CORRECT statements.

Consider the following statements concerning food chain : ( a) removal of 80% tigers from an area resulted in greatly increased growth of vegetation ( b) removal of most of the carnivores resulted in an increased population of deers ( c) the length of food chain is generally limited to 3-4 trophic levels due to energy loss ( d) the length of food chain may vary from 2-8 trophic levels

Study the following statements regarding food chains and select the correct ones. (i) Removal of 80% tigers from an area resulted in greatly increased growth of vegetation.
