Let's define what biodiversity is:
Biodiversity if the variety of different species within an ecosystem.
Now let's apply this information to answer our question:
We are trying to find which answer choice would not result in a loss of biodiversity, aka which of the answer choices increases the biodiversity.
0. Increase in pest populations because of loss of predators - this answer choice is ,correct,. We are ,increasing, a population in the ecosystem.
,1. Increase in the hole in the ozone - this answer choice is ,incorrect,. An increase in the hole of the ozone is ,dangerous, - it kills off populations of species living within an ecosystem.
,2. Impaired soil formation - this answer choice is ,incorrect,. If soil formation is incorrect, primary producers wouldn't be able to grow, affecting populations by decreasing them within an ecosystem.
,3. Less efficient water purification - this answer choice is ,incorrect,. If there is not enough water present in an ecosystem, it will cause populations to go down, ,decreasing, the biodiversity.
Therefore, our answer choice is A.
