What is a primary consumer?

Back

A primary consumer is an organism that eats producers (plants) to obtain energy. They are typically herbivores.

Front

What type of energy is transferred when animals eat other animals?

Back

Chemical energy is transferred as animals consume other organisms.

Front

Which trophic level has the least amount of energy?

Back

The tertiary consumer has the least amount of energy in a food chain.

Front

What does high biodiversity mean in an ecosystem?

Back

High biodiversity means that there are many different species living in an ecosystem.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organisms and return nutrients to the soil.

Front

What is a producer in an ecosystem?

Back

A producer is an organism that can make its own food, usually through photosynthesis, such as plants.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers (herbivores) to obtain energy.

Front

What is the difference between a scavenger and a decomposer?

Back

Scavengers consume dead animals, while decomposers break down dead organic matter and recycle nutrients.

Front

What is an example of a tertiary consumer?

Back

An example of a tertiary consumer is a hawk that eats snakes, which are secondary consumers.

Front

What is the significance of energy transfer in a food chain?

Back

Energy transfer is significant because it shows how energy moves from one trophic level to another, with energy decreasing at each level.
