Back

A community is a group of different species living together in one area.

What happens to the number of robins if most of the worms are killed?

Back

The number of robins will decrease because there are not enough worms to eat.

Front

How does the decrease in worms affect the number of foxes?

Back

The number of foxes will decrease because there will be fewer worms for the robins to eat, leading to fewer robins available for the foxes.

Front

Identify two organisms that share the same trophic level.

Back

Deer and sheep are examples of organisms that share the same trophic level.

Front

What is a keystone species?

Back

A keystone species is a species that has an unusually large effect on its ecosystem; if removed, many other species will die off.

Explain the concept of trophic levels.

Back

Trophic levels represent the different positions that organisms occupy in a food chain, based on their feeding relationships.

What is the role of producers in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the food chain.
