ecosystem: assimilation, dissimilation, decomposers, etc.

[DarDerk]

Source 1 shows a part of the energy flow diagram in an ecosystem.

1. Part P of the biomass of the primary producers does not get consumed. Give a concrete example of how this energy can get to the decomposers.

I think this can get to the decomposers, because the biomass simply dies. E.g. dead animals, dead trees, etc.

2. The amount of energy that is represented by R may end up with the decomposers in different ways. Name three ways.

I can come up with natural cell dead (dissimilation after assimilation).

3. The energy that is released through dissimilation, is not only released in the form of heat. What can this energy ‘Q’ be used for by the organism?

I think this energy (e.g. dissimilation of glucose) could be used for movements.
