<span>Succession increases biodiversity and helps to prevent too many places from desertification. Without biodiversity, there wouldn't be trees and the other organisms that play a part in keeping an enviroment cool. </span>
Clay is the least permeable type of soil. So the answer would be D-Clay
Because humans and all other organisms use some combination of these elements. if we lost a whole species everything would be out of balance and we would slowly lose everything and in the in, causing a global scale extinction event. <span />
Answer: (B) Pre-zygotic; post-zygotic.
Explanation:
Prezygotic isolation occurs before fertilization of eggs. It occurs between the two sex gametes and deter sexual reproduction between different species.
However, individuals are considered to be diverge on the phylogeny tree and different species, when they cannot reproduce.
Mechanisms of prezygotic isolation include habitat isolation, gamete isolation, mechanical isolation, behavioral isolation, and mating seasons.
Whereas, postzygotic isolation prevents the formation of fertile offspring. This phenomenon leads to production of an hybrid offspring from different species and this is a form of speciation in nature.
Mechanisms of postzygotic isolation include hybrid inviability, hybrid breakdown, and hybrid sterility.
