Question

Which of these statements relating to ecological succession is true?

During succession, there is no change to the physical or chemical environment.
During succession, existing species resist interaction with new species.
During succession, new species move into an area and colonize it.
Most ecological successions occur over 10 to 15 years.

Answer 1

Answer: During succession, new species move into an area and colonize it.

Explanation: Ecological succession refers to the process of change in the composition and structure of an ecosystem over time. It occurs due to the interactions between the biotic (living) and abiotic (non-living) components of an environment. As succession progresses, new species gradually establish and thrive in the area, leading to a change in the species composition. This process can occur over a long period of time, ranging from decades to centuries, depending on various factors such as environmental conditions and the specific type of succession.
