term
biological surplus
climax community
secondary succession
limiting factor
definition
a) a point in an ecosystem when all populations reach a point of little or no change
b) when there are more organisms in a population than the ecosystem can sustain
c) redevelopment of a habitat that has been disturbed by an event such as a forest fire or a hurricane
d) anything that can slow or stop the growth of a population

Explanation:

• Biological surplus (A): It refers to a situation where there are more organisms in a population than the ecosystem can sustain. This concept is related to population dynamics and ecosystem carrying capacity.
• Climax community (B): A climax community is a stable and mature ecological community where all populations reach a point of little or no change. It represents the final stage of ecological succession.
• Secondary succession (C): Secondary succession is the redevelopment of a habitat that has been disturbed by an event such as a forest fire or a hurricane. It occurs in an area where a pre - existing ecosystem has been disrupted.
• Limiting factor (D): A limiting factor is anything that can slow or stop the growth of a population. It can be a biotic (e.g., competition for food) or abiotic (e.g., lack of water) factor.

Answer:

• Biological surplus: A) a point in an ecosystem when all populations reach a point of little or no change
• Climax community: B) when there are more organisms in a population than the ecosystem can sustain
• Secondary succession: C) redevelopment of a habitat that has been disturbed by an event such as a forest fire or a hurricane
• Limiting factor: D) anything that can slow or stop the growth of a population
