Front

What is the efficiency of energy transfer from a lower trophic level to the next highest level?

Back

Roughly 10%.

Front

What does a secondary consumer eat?

Back

Secondary consumers eat primary consumers.

Front

What is the model of energy available at each level that decreases as you go up?

Back

The energy pyramid.

Front

What do primary consumers eat?

Back

Front

Why is there a limited amount of energy that can be passed on to the next feeding level?

Back

Organisms use some of the energy they get from eating.

Front

Define a producer in an ecosystem.

Back

Producers are organisms that create their own food through photosynthesis, such as plants.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, representing the flow of energy and nutrients.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem.

Front

Explain the term 'biomass pyramid'.

Back

A biomass pyramid illustrates the total mass of living matter at each trophic level.
