Question

When a large number of species, sometimes entire major taxa, go extinct in a short period of time on the geological scale, the cause is usually

A. Competition with other species
B. A large forest fire
C. Radical global climate change
D. Predation by a new type of hunter

Answer 1

Answer: C. Radical global climate change.

Step-by-step explanation:

The entire taxa of the species can be wiped out due to an large catastrophic event associated with the change in the climate. As the climate becomes warm the chances of undergoing the global precipitation rate will change. The climate being an important abiotic factor under unstability is likely to affect the amount of rainfall, snow fall, drought and conditions of desertification. All these factors can be responsible for the removal of the entire taxa of the species in short time.
