Endangered species are a concern to conservationists because there’s a risk that the animals won’t be able to adapt to their environment. one main cause of the inability to adapt is a)low genetic diversity b)a high rate of genetic mutation c)reproduction with an unrelated mate. both natural forces and human activities cause the endangerment of species. one situation that can be caused by both nature and humans is a)forest fires b)the burning of fossil fuels c)the removal of trees for lumber .

1 The correct answer is (A) low genetic diversity.

If a population is having a high genetic variability then there is a high chances that the species will survive and reproduce in harsh conditions. Variation provides the reason for the survival of species. If a specie is having low genetic diversity then there are chances that the species can lie into endangered species.

2 The correct answer is (A) forest fires

A forest fire can be caused by both natural forces and human activities. Human beings can also aid to forest fire for the construction work in that particular area. A natural force can also aid to forest fire by any means.
