Population Ecology

Front

What happens to population density as it becomes more dense?

Back

Competition for resources increases

Front

What role does competition play in population ecology? Options: It increases the carrying capacity, It limits population growth, It has no effect on population size, It promotes unlimited growth

Back

It limits population growth

Front

What would happen to a population with unlimited resources?

Back

It would grow exponentially

Front

What is an example of a natural event that can limit population growth?

Back

Drought or fire

Front

Why do populations not grow exponentially indefinitely?

Back

Because of limiting factors like competition and natural disasters

Front

What is carrying capacity?

Back

The average number of individuals an environment can support

Front

Which of the following is a limiting factor for population growth?

• Constant predator absence
• Infinite water sources
• Nutrient availability
• Unlimited space

Back

Nutrient availability

Front

What happens during overgrazing by herbivores?

Back

Population crash occurs

Front

How does the growth rate change as a population nears its carrying capacity?

Back

It decreases to zero
