Question

Population of California Candor is declining due to

• A. Increasing pollution
• B. Increasing cleanliness
• C. Change in surroundings
• D. Increasing pesticide concentration

Answer 1

Answer: (A)

The correct option is A Increasing pollution
The California condor is a New World vulture, the largest North American land bird. It became extinct in the wild in 1987, but the species has since been reintroduced to northern Arizona and southern Utah, the coastal mountains of central and southern California, and northern Baja California. As condors forage exclusively on dead animals, they are especially susceptible to lead exposure from carcasses which are left in the field. Lead poisoning from spent ammunition is the number one cause of death among endangered condors in the wild.

So, the correct answer is 'Increasing pollution'.
