Suppose that the efficiency of energy transfer among trophic levels in a community were magically increased. Which of the following would be a likely outcome?

Question

Group of answer choices

There would be more keystone species.

None of the above is a possible outcome.

There would be more trophic levels.

The level of primary production would increase dramatically.

The community would have many more decomposers.

Answer 1

If the efficiency of energy transfer among trophic levels in a community were magically increased, a likely outcome would be:

There would be more trophic levels.

Increased energy transfer efficiency means that more energy is available to support additional trophic levels, as less energy is lost between levels. This could allow for a greater number of consumers and potentially more complex food webs. Other options such as an increase in primary production or more decomposers may not necessarily follow from increased energy transfer efficiency.
