What type of growth is shown on this graph?

Back

Logistic growth is characterized by an initial exponential growth phase followed by a slowdown as the population reaches its carrying capacity.

Front

Back

Invasive Species are organisms that are introduced to a new environment and disrupt the local ecosystem.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas, while secondary succession occurs in areas where a disturbance has destroyed an existing community.

What is carrying capacity?

Back

Carrying capacity is the maximum population size that an environment can sustain indefinitely without degrading.
