Honors Unit 2 (Flashcard 4): Pulse Check - 24

Front

What happened to the rabbit population in Australia after they were introduced in the 1800s?

Back

The rabbits began to overpopulate greatly.

Front

What does it mean when a population has reached its carrying capacity?

Back

It means the population size has stabilized and is no longer increasing significantly due to limited resources.

Front

What are pioneer species in primary succession?

Back

Examples of pioneer species include mosses and lichens.

Front

What type of ecological succession occurs after a disturbance that does not destroy the soil?

Back

Secondary succession.

Front

What are some effects of climate change on ecosystems?

Back

Climate change can alter species distributions, affect migration patterns, and change the timing of biological events.

Front

What is the definition of carrying capacity in an ecosystem?

Back

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

Front

What role do pioneer species play in ecological succession?

Back

Pioneer species help to create conditions suitable for other species by breaking down rock and adding organic material to the soil.

Front

How can overpopulation of a species affect an ecosystem?

Back

Overpopulation can lead to resource depletion, habitat destruction, and increased competition among species.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, while secondary succession occurs in areas where a disturbance has destroyed an existing community but left the soil intact.

Front

What factors can limit population growth in an ecosystem?

Back

Factors include food availability, predation, disease, and competition.
