Question
At each trophic level, most of the energy is lost through biological processes.
- True
- False
Hint:
Every organism needs energy for its own biological processes.
The correct answer is 'True'.
- It is true to say that, at each trophic level, most of the energy is lost through biological processes.
- Every organism needs food for its growth, maintenance, and survival. In a food chain, one organism feeds on the other to meet these needs. For ex, grasshopper eats grass, lizard eats grasshopper, and hawk eats lizard. In this food chain, grass, grasshopper, lizard and hawk are the different trophic levels.
- But it should be noted that at each trophic level, the energy decreases. This is because at each level, the organism uses most of the energy for it own metabolism and maintenance and the rest is passed on to the further trophic level.
Energy always flows in a unidirectional way. It never comes to a downwards trophic level.
