Back

100 Kcal

Front

What does a biomass pyramid compare?

Back

The amount of biomass at each trophic level.

Front

In this energy pyramid, which organisms have the most energy available?

Back

Producers.

Front

How much of the energy in each level of an ecological pyramid gets LOST as heat or used by the organism so that it CANNOT be passed on to the next trophic level?

Back

90%.

Front

What is a trophic level?

Front

What are producers in an ecosystem?

Back

Producers are organisms that create their own food through photosynthesis, such as plants.

Front

What role do herbivores play in an energy pyramid?

Back

Herbivores are primary consumers that eat producers and transfer energy to the next trophic level.

Front

What is the significance of the 10% rule in energy transfer?

Back

The 10% rule states that only about 10% of the energy from one trophic level is passed to the next level.

Front

What is a top predator?

Back

A top predator is an organism at the top of the food chain with no natural enemies.
