Question

which of the following is not a cause of the biodiversity crisis discussed in class?
a continental drift (continents are moving away from each other naturally)
b habitat destruction
c introduction of new species in an ecosystem that wipes out the native species
d excessive exploitation for leisure and sports
e a. and d.

Explanation:

To determine the answer, we analyze each option:

• Option A: Continental drift is a natural, slow geological process that has occurred over millions of years and is not a direct human - caused factor of the current biodiversity crisis (which is driven by human activities like habitat destruction, invasive species introduction, over - exploitation, etc.).
• Option B: Habitat destruction (e.g., deforestation, urbanization) is a major human - caused factor leading to loss of species and biodiversity.
• Option C: Introduction of non - native (invasive) species can outcompete, prey on, or otherwise harm native species, leading to a decline in biodiversity.
• Option D: Excessive exploitation for leisure and sports (e.g., overfishing for sport, overhunting) is a human - caused activity that reduces populations of species and affects biodiversity.
• Option E: Since Option A is not a cause of the current biodiversity crisis (while Option D is a cause), this option is incorrect.

So, the option that is not a cause of the biodiversity crisis is Option A.

Answer:

A. Continental drift (continents are moving away from each other naturally)
