< Prev
Next >

A researcher studying ecological succession plants a variety of species in an area previously covered by ice to observe primary succession. They conclude that primary succession does not occur because the planted species thrived. What conceptual mistake was made?

A

Assuming that the success of planted species indicates a bypass of the primary succession stages.

B

Failing to recognize that primary succession involves pioneer species naturally colonizing the area, not human intervention.

C

Overlooking the role of pioneer species like lichens and mosses in preparing the environment for later species.

D

Misunderstanding primary succession as involving the introduction of species, rather than the natural colonization and succession process.
