Energy Pyramid Review

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the flow of energy through different trophic levels in an ecosystem, illustrating how energy decreases as it moves from producers to top consumers.

Front

What is the first trophic level in an energy pyramid?

Back

The first trophic level consists of producers, such as plants and algae, which convert sunlight into energy through photosynthesis.

Front

How much energy is typically transferred from one trophic level to the next?

Back

Typically, about 10% of the energy is transferred from one trophic level to the next.

Front

What happens to the remaining energy that is not transferred to the next trophic level?

Back

The remaining energy is lost as heat, used for metabolic processes, or not consumed by the next trophic level.

Front

What are primary consumers?

Back

Primary consumers are organisms that eat producers; they are typically herbivores that obtain energy by consuming plants.

Front

What are secondary consumers?

Back

Secondary consumers are organisms that eat primary consumers; they can be carnivores or omnivores.

Front

What are tertiary consumers?

Back

Tertiary consumers are organisms that eat secondary consumers; they are often at the top of the food chain.

Front

Why are grasses and shrubs considered producers?

Back

Grasses and shrubs are considered producers because they convert sunlight into glucose through photosynthesis.

Front

If the first trophic level has 6,000 J of energy, how much energy is available at the second trophic level?

Back

600 J of energy is available at the second trophic level.

Front

What role do decomposers play in an energy pyramid?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and completing the energy cycle.
