Food Pyramids & Trophic Levels

Front

What is the energy transfer efficiency from producers to primary consumers?

Back

Typically, only about 10% of the energy from producers is transferred to primary consumers.

Front

What is the primary role of producers in an ecosystem?

Back

Producers use sunlight to make food through the process of photosynthesis.

Front

What is an example of a primary consumer?

Back

A grasshopper is an example of a primary consumer.

Front

What happens to energy as you move up the trophic levels in an energy pyramid?

Back

The energy decreases as you move up the trophic levels.

Front

Define a consumer in ecological terms.

Back

A consumer is an organism that needs to eat other organisms to obtain energy.

Front

What is the primary source of energy for producers?

Back

The primary source of energy for producers is sunlight.

Front

What is the difference between a producer and a consumer?

Back

Producers create their own food using sunlight, while consumers obtain energy by eating other organisms.

Front

What is a trophic level?

Back

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

Front

How does energy flow in an ecosystem?

Back

Energy flows from producers to primary consumers, then to secondary consumers, and so on, with energy decreasing at each level.

Front

What is the significance of the 10% rule in ecology?

Back

The 10% rule indicates that only about 10% of the energy is passed on to the next trophic level.
