Introduction:
Biodiversity is a variety of life in an area that is determined by the number of species living in that area. It helps in maintaining a healthy biosphere and provides direct and indirect value to humans. Biodiversity increases the stability of an ecosystem. Human activities have affected many ecosystems. Conservation biologists are working to slow down the loss of biodiversity.
Answer to Problem 5MI
Correct answer :
The correct answer is option B.
Explanation of Solution
Explanation/justification for the correct answer:
Option B.
Conservation ecologists are trying to improve the survival of biodiversity by providing corridors or passageways between habitat fragments. Corridors are used to connect smaller parcels of land. These corridors allow organisms from one area to move safely to another area. This creates larger piece of land that can sustain a wider variety of species. The habitats must be completely separate but there should be a connection bridge between them. Hence this is the correct option.
Explanation for incorrect answer:
Option A.
This does not correctly represent a habitat corridor as the two areas are overlapping. The habitats must be completely separated from each other.
Option C.
In this diagram the habitats are separate but they are not connected with each other. Hence it does not represent a habitat corridor.
