When an ecosystem is affected by loss of shelter, what happens to the populations in that ecosystem?
A
They can decrease or die out
B
They are usually not affected
C
They can readily adapt to the changes
D
The populations increase
Explanation: 

Detailed explanation-1: -When a habitat is destroyed, the carrying capacity for indigenous plants, animals, and other organisms is reduced so that populations decline, sometimes up to the level of extinction. Habitat loss is perhaps the greatest threat to organisms and biodiversity.

Detailed explanation-2: -Habitat loss can fragment ecosystems and can cause species extinctions, while habitat restoration can increase local biodiversity and species populations. The evolution of life cycles and traits that help species survive and reproduce in distrubed or altered ecosystems.

Detailed explanation-3: -The loss of biodiversity limits ecosystems’ evolutionary potential to continue to produce new, therapeutic plant varieties, as well as missing out on potentially useful compounds that are lost before the species that bear them have been recorded.

Detailed explanation-4: -The impact of ecosystem destruction are the following: Increased flooding due to the erosion of soil and lack of trees. Rising of the sea levels due to the melting of the glaciers, caused by Global Warming. Disruption of the food chain when the apex predators become extinct.
