Introduction :
Biodiversity is the variety of life in an area that is determined by the number of various species in that area. But, many species lost their habitat due to some factors. These factors may effects the biodiversity. There are several ways that species can lose their habitats. If a habitat is disrupted or destroyed, the native species might have to relocate or they will die.
Answer to Problem 22A
Correct answer :
The correct answer is option (A) background extinction.
Explanation of Solution
Explanation/justification for the correct answer :
Option (A) background extinction. Background extinction is the ongoing extinction of species due to ecological or environmental factors. It is not the way in which a species lost their habitat. So, the correct answer is option (A).
Explanation for incorrect answer :
Option (B) destruction. Destruction is the way in which species lost their habitat. Destruction of habitat will cause many species on the earth to become extinct because of habitat loss. So, this is an incorrect option.
Option (C) disruption. Habitat might not be destroyed but they can be disrupted. In the coast of Alaska, the chain of events occurred in the 1970s that demonstrates how the declining numbers of one member of food web can affect the other members. The decline of one species can affect the entire ecosystem. So, this is an incorrect answer.
Option (D) pollution. The pollution threatens biodiversity and global stability. Pollution changes the composition of air, soil, and water which may lead to the extinction of different species. So, this is an incorrect answer.
