Question

practice it! select the statement that accurately summarizes the pathway of energy through trophic levels. energy is perfectly transferred from one trophic level to the next. energy is recycled back into the ecosystem. energy transfer is linear and requires a constant input source. producers obtain energy from water and nutrients in the soil.

Explanation:

Energy transfer between trophic levels is not perfect (about 10 - 20% is transferred), energy is not recycled in the same way as nutrients in an ecosystem, and producers obtain energy mainly from sunlight via photosynthesis. Energy transfer in an ecosystem follows a linear path from the sun to producers and then to various levels of consumers and requires a constant input of solar energy.

Answer:

Energy transfer is linear and requires a constant input source.
