The answer is; D
The angle at which the sun rays strike the earth at the equator is more or less 90 degrees while you move towards the poles, it much less than this. This means that the unit of sunlight per surface area received at the equator is higher than that at the poles. This is why the equator is always warmer than the poles.
Answer:
how changes in biodiversity impact an ecosystem
Explanation:
Water hyacinth is a free-floating perennial aquatic plant. This plant is native to tropical and sub-tropical South America. As an invasive species, when it grows in the new environment causes severe ecological or economic harm. By growing where it not native, it can spread extremely fast, blanketing a water surface in a very short period of time. It can limit boat traffic, swimming, and fishing, and it can deprive native plants and animals of sunlight and oxygen, thus reducing the local biodiversity.
This is how an ecosystem effects biodiversity impact. When a biological species grows in the new environment, It can affect the biodiversity or environment that can affect the biological species.
