The energy flow along a food chain, and the number of individuals at each level, gradually decreases as we go higher up?
Answers
Answer:
Explanation:
the energy flow decrease with increasing level in food chain because the energy gained by the organism is used in maximum amount for the metabolic functioning of that organism . so very less amount of energy is transfered to next level of food chain
This can be also justified by 10 percent law
For eg
Deer feed on grass . It use maximum amount of energy in its daily activity and metabolic function .So very less amount of energy can be gained by lion who feeds on it.
The number of organism decreases because the amount of energy decrease .
As when there is less energy only some of the same level organism will survive as they require more food to survive .
Answer:
As we go higher up, the amount of energy transferred decreases hence resulting in a decrease in the number of individuals at each level. 90 % of energy is used by the organism for metabolic processes and the rest 10 % is transferred ahead
