If grassland is treated as empty land and construction is done on it, what will be the effect on conservation?

Correct answer: Habitat of grassland-based organisms will decrease

Grasslands are not empty or useless areas. They support grasses, insects, birds, herbivores, predators, soil organisms, and sometimes important wildlife movement routes. When construction replaces a grassland, the plants and shelter available to these organisms are reduced. Roads and buildings can also divide the habitat into smaller pieces, making movement and feeding more difficult.

The correct choice is A, because construction decreases the habitat available to organisms that depend on grasslands. It does not give all animals more space, create wildlife corridors automatically, or end pollution. Treating grassland as vacant land ignores its ecological value. Conservation planning must identify the species and services supported by the grassland before approving construction.
