Unit 3- Populations and Resources (Amplify)

Front

What is competition in ecology?

Back

Competition occurs when two or more populations use the same resource, leading to a struggle for that resource.

Front

How does an increase in one population affect another population?

Back

An increase in one population can lead to a decrease in another population if they compete for the same resources.

Front

What does a decreasing population model indicate?

Back

A decreasing population model indicates that the number of individuals in a population is declining over time.

Front

What factors can cause a population to increase?

Back

Factors such as an increase in available resources or a decrease in predators can lead to a population increase.

Front

What is a consumer in an ecosystem?

Back

A consumer is an organism that eats other organisms or organic matter for energy.

Front

What is a resource in an ecosystem?

Back

A resource is any substance or factor that is necessary for the survival and growth of organisms, such as food, water, and shelter.

Front

What is the relationship between predator and prey populations?

Back

Predator and prey populations are interdependent; an increase in prey can lead to an increase in predators, and vice versa.

Front

What is the role of birth and death rates in population dynamics?

Back

Birth and death rates determine whether a population is increasing, decreasing, or remaining stable.

Front

How can changes in one species affect another species?

Back

Changes in one species, such as a decrease in food supply, can directly impact the population of another species that relies on it.

Front

What is an example of indirect effect in ecology?

Back

An indirect effect occurs when a change in one population affects another population through a third population, such as a predator affecting prey indirectly.
