Question

Choose all the answers that apply. Energy in an ecosystem: flows only one way is part of an open system is recycled and reused is eventually lost as heat is transferred through the food chain

Answer 1

Energy in an ecosystem "is recycled and reused" but this could also easily be "is transferred through the food chain", since the two processes are quite similar.

Answer 2

Answer:

The correct answers would be:

• flows only one way
• is eventually lost as heat
• is transferred through the food chain

In contrast to nutrient, energy flow only in one direction only in an ecosystem.

In an ecosystem, the energy is transferred through food chain. The producers convert solar into chemical energy. 10 percent of available energy is then transferred to the next trophic level (herbivores) and rest of the energy is lost as heat.

Similarly, the energy is passed on to secondary and tertiary trophic levels.

Ultimately, the energy is lost as heat released during decomposition.
