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 predators.

Front

What are producers in an energy pyramid?

Back

Producers are organisms that create their own food through photosynthesis, typically found at the base (first bottom) of the energy pyramid.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or energy pyramid that indicates the organism's role in the flow of energy, such as producers, primary consumers, secondary consumers, and tertiary consumers.

Front

What happens to the energy as it moves up the energy pyramid?

Back

As energy moves up the energy pyramid, it decreases significantly, with only about 10% of the energy being transferred to the next trophic level.

Front

Who are primary consumers?

Back

Primary consumers are herbivores that eat producers (plants) and are found at the second level of the energy pyramid.

Front

What is the role of predators in an ecosystem?

Back

Predators are organisms that hunt and eat other organisms (prey), helping to maintain the balance of populations within an ecosystem.

Front

What is prey?

Back

Prey are organisms that are hunted and eaten by predators.

How does the death of a species affect the food chain?

Back

The death of a species can disrupt the food chain, leading to population increases or decreases in other species that are directly or indirectly connected.

Front

What is the significance of the energy transfer efficiency in an ecosystem?

Back

Energy transfer efficiency is significant because it determines how much energy is available to support higher trophic levels, affecting the overall health and sustainability of the ecosystem.

What is a food web?

Back

A food web is a complex network of interconnected food chains that illustrates how energy and nutrients flow through an ecosystem.
