Ecological Energy Pyramids

Front

What happens to energy as you move up an energy pyramid?

Back

Energy decreases.

Front

Which organisms have the most energy available in an energy pyramid?

Back

Producers.

Front

What is the 10% rule in the context of energy transfer between trophic levels?

Back

The 10% rule states that approximately 10% of energy is transferred from one trophic level to the next.

Front

If the producers level contains 1234 kilocalories, how many kilocalories are transferred to the primary consumer level?

Back

123.4 kilocalories.

Front

If there is 1000 Kcal available at the producers level, how much energy is available in the primary consumers level?

Back

100 Kcal.

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.

Front

What are the primary trophic levels in an energy pyramid?

Back

Producers, primary consumers, secondary consumers, and tertiary consumers.

Front

Why is energy transfer in an ecosystem inefficient?

Back

Energy transfer is inefficient due to energy loss as heat and through metabolic processes at each trophic level.

Front

What role do producers play in an energy pyramid?

Back

Producers convert solar energy into chemical energy through photosynthesis, forming the base of the energy pyramid.

Front

What is the significance of the base of the energy pyramid?

Back

The base of the energy pyramid represents the largest amount of energy available, which is primarily from producers.
