Question

Explain how energy is passed from one organism to another within a food chain?

Answer 1

Answer:

Energy is transferred along food chains from one trophic level to the next. However, the amount of available energy decreases from one trophic level to the next.

Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.

Answer 2

Answer:

Explanation:

In a food chain only around 10 per cent of the energy is passed on to the next trophic level. The rest of the energy passes out of the food chain in a number of ways: it is used for life processes (eg movement) faeces and remains are passed to decomposers.
