Unit 7 Formative Exam Review

Front

What is migration in animals?

Back

Migration is the seasonal movement of animals from one region to another, often for breeding or feeding purposes.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species.

Front

What is the impact of decreased populations of a species on the ecosystem?

Back

Decreased populations can lead to imbalances in the ecosystem, affecting food chains and the survival of other species.

Front

What role do pesticides play in ecosystems?

Back

Pesticides can harm non-target species, disrupt food chains, and lead to declines in populations of beneficial organisms.

Front

What is a protected area?

Back

A protected area is a designated region where human activity is restricted to conserve wildlife and natural resources.

Front

How does overfishing affect marine ecosystems?

Back

Overfishing can lead to the depletion of fish populations, disrupting the balance of marine ecosystems and affecting other species.

Front

What is the significance of female spawning age in fish populations?

Back

Female spawning age is crucial because older females typically produce more eggs, contributing to the sustainability of fish populations.

Front

What are the consequences of introducing non-native species?

Back

Introducing non-native species can disrupt local ecosystems, outcompete native species, and lead to biodiversity loss.

Front

What is the relationship between food sources and animal survival?

Back

Availability of food sources is essential for animal survival; a lack of food can lead to population declines and extinction.

Front

What is the effect of habitat destruction on wildlife?

Back

Habitat destruction can lead to loss of shelter and food, resulting in population declines and increased risk of extinction.
