Environmental Science: Understanding Populations

In which type of interaction between species does ONE species BENEFIT by HARMING ANOTHER species but not killing it?

• predation

• parasitism

• mutualism

• commensalism

A species of plant has exponential growth after it is introduced into an area where it has never lived. Which statement BEST DESCRIBES EXPONENTIAL GROWTH?

• Each individual plant grows much larger than usual.

• The population immediately decreases.

• Within a few years, the population increases dramatically.

• The species’ reproductive potential declines.

A bird that feeds at NIGHT and a bird that feeds during the DAY from the same flower is an example of

• direct competition

• mutualism

• indirect competition
