Answer:
D:) sunlight
Explanation:
Sunlight is one of the resources that are available in limited quantity in water bodies as compared to the land habitats since sunlight can penetrate up to a certain depth in water. However, land habitats have ample of sunlight available for plants. During early colonization of land habitats, dense forests were not present on land which in turn made even more sunlight available to the land plants of all height. Sunlight is one of the required factors to support plant growth and development.
The genetic equilibrium represents the condition of a genotype or an allele in the genetic pool of a particular population, where there are no changes in the frequency in the successive generations. This basically means that the population has managed to reach the peak of its evolution for the environment in which it leaves, so there's no evolutionary pressure for changes.
In order for the genetic equilibrium to be maintained for prolonged period of time, the population should not face any evolutionary pressure that will cause changes in it. In essence, this means that the environment in which the population lives should remain exactly the same as it is for longer period of time, so the population will have no need to change its appearance or behavior.
Answer:
C Volcanic activity releasing carbon into the atmosphere.
Explanation:
The statement that best describes the cycling of carbon between the atmosphere and geosphere among the options is volcanic activity that leads to releasing carbon into the atmosphere.
Volcanic activities has to do with the activity of the geological layer of the earth that leads to the emission of gases, eruption of lava or the combination of the two.
When a volcanic activity leads to the release of carbon related gases such as carbon dioxide into the atmosphere, carbon is being circulated between the geosphere (the earth) and the atmosphere (the air).
Hence, the correct option is C.

I’m not sure about what the article says , but from my knowledge:
1. Only a small percent of the sea has been discovered. As marine studies progress and discover more and more areas, they realize there is more than their estimate. Plus, the population is constantly changing.
2. As of now, it’s believed that there is around 1 to 9 million species in coral reefs
3. This is because it houses an incredible amount of different species. And is structurally a perfect area for sea animals to live and thrive.
