Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is a characteristic of a habitat in the earliest stages of succession?
A
Relatively low biodiversity
B
Mostly hardwood trees
C
Thick layer of rich soil
D
High density of organic matter
Explanation: 

Detailed explanation-1: -Early successional plants tend to have high rates of photosynthesis and respiration, high rates of resource uptake, and high light compensation points, whereas late successional plants often have opposite characteristics (Bazzaz 1979).

Detailed explanation-2: -The 5 stages of succession are Nudation, Invasion, Competition and Co-action, Reaction, and Climax or Stabilization. At the same location, a succession of biotic communities naturally emerge one after another until the Climax stage is reached. In their early stages, biotic communities develop slowly.

Detailed explanation-3: -The first stage of succession involves pioneer species. In primary succession, pioneer plants are those that can grow without soil, such as lichens. Lichens begin breaking down a rock.
