Effects of Population Size

Front

What limits the number of populations an ecosystem can support?

Back

Factors such as temperature, water availability, food resources, and space can limit the number of populations an ecosystem can support.

Front

What is a predator?

Back

A predator is an organism that hunts and eats other organisms (prey) for food.

Front

What is competition in an ecosystem?

Back

Competition occurs when organisms vie for the same resources, such as food, water, space, and shelter.

Front

What happens to a population when a new predator is introduced?

Back

The population of prey species may decrease, which can also affect the populations of other species in the ecosystem.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support.

Front

How does food availability affect population size?

Back

If food is abundant, populations can grow; if food is scarce, populations may decline.

Front

What role does temperature play in an ecosystem?

Back

Temperature can determine which species can survive in an ecosystem, affecting population sizes.

Front

What is the relationship between predators and prey?

Back

Predators control the population of prey species, which can help maintain balance in the ecosystem.

Front

What is an example of a resource that organisms compete for?

Back

Organisms compete for resources such as space, water, food, and shelter.

Front

How can a change in water levels affect animal populations?

Back

Changes in water levels can impact food availability and habitat, influencing population sizes.
