Question

what is biological surplus? the amount by which the number of young exceeds the adult population in an area after birthing season the necessary population increase for a species to be removed from the endangered species list the number of animals in a population beyond the carrying capacity the population of invasive species—both animals and plants—in a given area

Explanation:

To determine the correct definition of biological surplus, we analyze each option:

• Option 1: Compares young and adult populations post - birthing, not related to biological surplus.
• Option 2: Talks about population increase for endangered species delisting, not biological surplus.
• Option 3: Biological surplus is the number of animals in a population that exceeds the carrying capacity (the maximum number of individuals an environment can sustainably support). This matches the concept.
• Option 4: Refers to invasive species population, not biological surplus.

Answer:

C. The number of animals in a population beyond the carrying capacity
