What is a population in ecological terms?

Back

A population is a group of the same species in the same geographic area.

Front

True or False: A stable ecosystem typically has high biodiversity.

Back

True

Front

What does it mean if a biome has low biodiversity?

Back

It means there are fewer different species present, making the ecosystem more vulnerable to changes.

Front

How does biodiversity contribute to ecosystem services?

Back

Biodiversity supports ecosystem services such as pollination, nutrient cycling, and water purification.

Front

What is an example of a biome with high biodiversity?

Back

Tropical rainforests are an example of a biome with high biodiversity.

Front

What is an example of a biome with low biodiversity?

Back

Deserts are an example of a biome with low biodiversity.

Front

What is the relationship between biodiversity and extinction?

Back

High biodiversity can reduce the risk of extinction for species, as ecosystems are more stable.

Front

What role do keystone species play in an ecosystem?

Back

Keystone species have a disproportionately large impact on their environment, helping to maintain the structure of the ecosystem.
