Introduction :
Biodiversity is often lost in an environment due to which the abiotic and biotic factors that required a healthy ecosystem are no longer available. People are using many approaches to slow the rate of extinctions and to preserve biodiversity. Around half of all species of plant and animal are found in the hot spots. Originally, these hot spots occupied 15.7 per cent of Earth's surface, but just about one-tenth of that area remains.
Answer to Problem 33A
Correct answer :
The correct answer is option (D) Members of species can move safely from one area to another.
Explanation of Solution
Explanation/justification for the correct answer :
Option (D) Members of species can move safely from one area to another. The advantage of habitat corridor is that it improves the survival of biodiversity by providing corridors, or passageways, between habitat fragments that help to connect smaller parcels of land and allow organisms to move safely from one place to another. So, the correct answer is option (D).
Explanation for incorrect answer :
Option (A). Corridors increase the edge effect in the area. One large habitat would have fewer edges, but often a large habitat is hard to preserve. Therefore, this is a disadvantage of the habitat corridor. So, this is an incorrect option.
Option (B) Diseases are passed easily from one area to another. Diseases can easily pass from one area to the next as infected animals can also move from one location to another. Therefore, this is a disadvantage of the habitat corridor. So, this is an incorrect answer.
Option (C)
