Question

Where is most of the energy assimilated in a lake ecosystem found?

a) in secondary consumers such as small fish
b) in tertiary consumers such as large fish
c) in producers such as algae
d) in primary consumers such as zooplankton

Answer 1

In a lake ecosystem, the primary source of energy assimilation is found in producers such as algae.

Step-by-step explanation:

In a lake ecosystem, most of the energy assimilation is found in c) producers such as algae.

In many ecosystems, the base of the food chain consists of photosynthetic organisms (plants and/or phytoplankton), which are called primary producers.

These producers convert light energy through photosynthesis.

The energy is then passed on to primary consumers, such as zooplankton, who feed on the producers and assimilate the energy.

Therefore, the energy assimilation in a lake ecosystem is primarily found in the producers at the bottom of the food chain.
