Back

A species that plays a critical role in the health, maintenance, growth, or definition of an ecosystem.

Front

What happens to an ecosystem if a keystone species is removed?

Back

The ecosystem may become unbalanced, leading to a decline in biodiversity and changes in population dynamics.

Front

Give an example of a keystone species.

Back

Bees are considered a keystone species because they pollinate flowers that produce fruit, supporting the ecosystem.

Front

What is an invasive species?

Back

A species that does not belong in a certain ecosystem and can disrupt the balance of that ecosystem.

Front

How do keystone species affect biodiversity?

Back

Keystone species help maintain the structure of an ecosystem, which in turn supports a diverse range of species.

Front

What role do predators play in an ecosystem?

Back

Predators help control the population of prey species, maintaining balance within the ecosystem.

Front

What is the relationship between crickets and grass/flowers in an ecosystem?

Back

An increase in the cricket population can lead to a decrease in the grass/flowers population due to overconsumption.

Front

What might happen if frogs become extinct in a food chain?

Back

If frogs become extinct, the population of grasshoppers may increase due to the absence of their predator.

Front

Why are bees considered important for ecosystems?

Back

Bees pollinate flowers, which is essential for the production of fruits and seeds, supporting various life forms.

Front

What is the impact of removing a top predator from an ecosystem?

Back

Removing a top predator can lead to overpopulation of prey species, which may result in overgrazing and habitat destruction.
