Question

which of the following is an example of human activity that can have significant environmental consequences to other abiotic factors?
a the introduction of a new plant species affecting local species
b the regulation of hunting to maintain balanced wildlife populations
c an increase in pollutants in the air leading to the formation of other pollutants
d the overuse of pesticides leading to a decline in insect populations

Explanation:

• Option A: Involves biotic - biotic interaction (plant species affecting local species), not abiotic factors.
• Option B: Regulation of hunting affects wildlife (biotic), not abiotic factors.
• Option C: Air pollutants are abiotic. An increase in air pollutants (human - caused, like industrial emissions) leading to formation of other pollutants is a human activity affecting abiotic factors.
• Option D: Pesticide overuse affects insects (biotic), not abiotic factors.

Answer:

C. an increase in pollutants in the air leading to the formation of other pollutants
