📗 Energy Pyramids Review

Front

What is an autotroph?

Back

An autotroph is an organism that makes its own food, typically through photosynthesis or chemosynthesis.

Front

Why are producers found at the base of the energy pyramid?

Back

Producers are at the base because they create all of the energy and have the most energy of all trophic levels, beginning the flow of energy in an ecosystem.

Front

If there is 1000 Kcal available in the producers, how much energy is available in the herbivores?

Back

100 Kcal.

Front

Which organism has the least amount of energy available in an energy pyramid?

Back

Top Predator.

Front

True or False: Consumers on each level of the energy pyramid only get about 10 percent of the energy from the trophic level before it.

Back

True.

Front

What is a heterotroph?

Back

A heterotroph is an organism that cannot make its own food and relies on consuming other organisms for energy.

Front

What role do herbivores play in the energy pyramid?

Back

Herbivores are primary consumers that eat producers and transfer energy from the plant level to the animal level.

Front

What is biomass in the context of an energy pyramid?

Back

Biomass refers to the total mass of living matter in a given area, which decreases as you move up the energy pyramid.

Front

What happens to energy as it moves up the trophic levels?

Back

Energy decreases as it moves up the trophic levels, with only about 10% being transferred to the next level.

Front

What is a carnivore?

Back

A carnivore is an organism that primarily eats other animals.
