What happens to a population if its primary food source decreases?

Back

The population may decrease or die out due to lack of food.

What is the role of producers in an ecosystem?

Back

Producers, such as green plants, create their own food through photosynthesis and form the base of the food chain.

What is a consumer in an ecosystem?

Back

A consumer is an organism that cannot produce its own food and relies on eating other organisms (plants or animals) for energy.

How does habitat loss affect animal populations?

Back

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular ecosystem, including the number of different species and their interactions.

Front

What is the impact of overfishing on ecosystems?

Back

Overfishing can lead to the decline of fish populations, which can disrupt the food chain and affect other species that rely on them for food.
