Unit 5 review (ES)

Front

What does it mean when a population is described as 'stabilized'?

Back

A stabilized population is one that remains relatively constant in size over time, neither increasing nor decreasing significantly.

Front

What is the carrying capacity of an environment?

Back

The carrying capacity is the maximum number of individuals of a species that an environment can sustainably support without degrading the habitat.

Front

Why can't populations grow exponentially forever?

Back

Populations cannot grow exponentially forever because resources are limited, leading to competition and eventual stabilization.

Front

What is genetic diversity?

Back

Genetic diversity refers to the variety of genes within a species, which contributes to the resilience and adaptability of that species.

Front

How does genetic diversity enhance resilience in species?

Back

Genetic diversity enhances resilience by increasing a species' ability to adapt to environmental changes and challenges.

Front

What factors can lead to a population decline?

Back

Factors such as habitat loss, resource depletion, disease, and increased predation can lead to a population decline.

Front

What is the difference between a growing population and a declining population?

Back

A growing population is increasing in size, while a declining population is decreasing in size over time.

Front

What role do resources play in population growth?

Back

Resources such as food, water, and shelter are essential for population growth; limited resources can restrict growth.

Front

What is an example of a species with high genetic diversity?

Back

Humans are an example of a species with high genetic diversity, which contributes to our adaptability and survival.

Front

What happens to a population when it exceeds its carrying capacity?

Back

When a population exceeds its carrying capacity, it can lead to resource depletion, increased competition, and a subsequent decline in population size.
