Ecological Energy Pyramids

Front

What is an ecological energy pyramid?

Back

An ecological 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 predators.

Front

What are producers in an energy pyramid?

Back

Producers are organisms, typically plants, that create their own food through photosynthesis and form the base of the energy pyramid.

Front

What are primary consumers?

Back

Primary consumers are herbivores that eat producers and are the second level in the energy pyramid.

Front

What are secondary consumers?

Back

Secondary consumers are carnivores that eat primary consumers and are typically the third level in the energy pyramid.

Front

What are tertiary consumers?

Back

Tertiary consumers are top predators that eat secondary consumers and are at the highest level of the energy pyramid.

Front

What does biomass refer to in an energy pyramid?

Back

Biomass refers to the total mass of living organisms in a given area, which typically decreases at higher trophic levels in an energy pyramid.

Front

What is the significance of energy transfer in an energy pyramid?

Back

Energy transfer is significant because it illustrates how energy decreases at each trophic level, with only about 10% of energy being passed on to the next level.

Front

What do the arrows in an energy pyramid represent?

Back

The arrows in an energy pyramid represent the direction of energy flow from one trophic level to another.

Front

Why do producers have the most energy available in an energy pyramid?

Back

Producers have the most energy available because they convert sunlight into chemical energy through photosynthesis, which is then used by other organisms.

Front

What is the role of decomposers in an ecosystem?

Back

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