Show answer

Exponential growth

Exponential (J-shaped) growth occurs when resources are unlimited and every individual reproduces at maximum rate. The population grows faster and faster over time, giving a J-curve.

2multiple choice

The S-shaped growth curve of a population is called:

Show answer

Logistic growth curve

Logistic (S-shaped or sigmoid) growth occurs when resources are limited. Growth is initially exponential, then slows as the population approaches the carrying capacity (K), forming an S-curve.

3multiple choice

Carrying capacity (K) refers to:

Show answer

The maximum population size an environment can sustain indefinitely

Carrying capacity (K) is the maximum population size that a given environment can support indefinitely, given the food, water, shelter, and other resources available.
