Speciation is the divergence of two populations from a common ancestor. how does it contribute to biological diversity? (a) speciation increases biological diversity.(b) speciation has no effect on biological diversity.(c) speciation decreases biological diversity.

Option (A)

Explanation: The rate of speciation is directly proportional to the amount of biological diversity. This means that, the more is the speciation, the more will be its diversity.

Speciation is a process that helps us in understanding the evolutionary trend of any species and re-establish the various biodiversities existing on earth.

Thus the correct answer is option (A).

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
