Questions and Answers

Which of the following best describes the concept of 'Carrying Capacity'?

The maximum population size an environment can sustain. (correct)

The variety of genetic characteristics in a population.

The amount of biomass available in an ecosystem.

The total number of species in a specific area.

What effect does habitat fragmentation have on biodiversity?

It increases genetic diversity within species.

It enhances connectivity between habitats.

It leads to isolated populations, reducing species diversity. (correct)

It decreases competition among species.
