a) True

b) False

Answer 1

1. The leading cause for loss of biodiversity across the globe is A) habitat loss.

Habitat loss is caused by deforestation, overpopulation ,global warming.

2. When a once contiguous, undeveloped landscape is broken up into small parcels by the placement of road and housing development, this is termed as A) habitat intervention.

Habitat intervention means interfering into the natural habitat and destroying it for human use.

3. An organism classified as endangered is in a greater risk of becoming extinct than an organism that is classified as threatened.

A) True.

It is true because an endangered species is one which is likely to become extinct in near future and a threatened species is one which is likely to become endangered in near future.

4. The phenomena known as deforestation is unique to the tropical rainforest.

A) True

This statement is true because the deforestation is more extreme in tropical rainforest. More than half of animal and plant species in the world live in tropical rainforest. As a result of deforestation only 6.2 million square kilometre remains of the original 16 million square kilometre of tropical rainforest.
