Answer: Asexual reproduction causes less competition for resources.
Explanation:
Answer:
a. two plant species flowering at different times.
Explanation:
<em>The only option that is not a post-zygotic reproductive isolation mechanism would be option a, when two plant species flower at different times.</em>
Post-zygotic reproductive isolation mechanisms are those mechanisms that act to ensure that the product of fertilization remains invalid. This is as opposed to pre-zygotic isolation mechanisms that act to prevent fertilization and hence, formation of zygotes.
In option b, c, d and e; the zygote has been formed already and all the forces are just acting to ensure that it remains invalid. whereas in option a, there is no fertilization yet.
<u>Two plant species flowering at different times will ensure that there is no cross pollination between the two species. Without pollination, there cannot be a zygote formation.</u>
Hence, the correct option is a.
<span>Plants take up carbon dioxide from the air and nutrients from the soil. This is an example of interactions between biosphere, atmosphere and geosphere. The answer is letter B. Bioshphere is the representation of any living organism on earth such as plants and animals. Even the tiniest organism that cannot be seen is considered a part of biosphere. Atmosphere is the blanket of gases that wraps around the earth. We may not see it but we can feel it. Geosphere is the land itself, the earth as a whole. From the core,to mantle and to crust. So in the example given, plants represent the biosphere, carbon dioxide form air represents the atmosphere and soil represents geosphere.</span>
