Energy is gained at each trophic level, supporting less biomass at the top
Energy is lost at each trophic level, supporting less biomass at the top
Energy is gained at each trophic level, allowing more organisms to be represented on the top level
Energy is completely transferred from one trophic level to the next, with no energy lost as heat
4. How could an increase in a secondary consumer affect producers?
*

It could cause the population of the producers to increase, because they now have less primary consumers eating them.
It could cause the population of the producers to decrease, because they now have more primary consumers eating them.
It could cause the population of the producers to decrease by half
Secondary consumers have no effect on producers
