At the top of the body of a water, there is a lot of light from the sun, which also means a lot of solar energy. This allows for a fruitful photosynthesis.
In contrast, at the bottom of the water, there isn't as much, or sometimes any, sun light. Because of this the organisms at the bottom of the body of water
<span>D. must rely on other means than photosynthesis

Answer:
A process of change in a population through genetic variation.
Explanation:
Evolution is the process of change in heritable characteristics of populations of organisms over several generations as it allow natural selection in it.
Genetic variation which refers to differences in gene frequencies is an important force in evolution which relies of natural selection to cause an increase or reduce gene frequencies in a population. Evolution lead to changes in genetic material of populations over time which make them to develop genes that will allow them to adapt to their environment for survival and reproduction.
Answer: whats the answer choices?
The muscles moved quickly to defend themselves against this new predator by thickening their shells
The correct answer is option D, that is, it will increase the amount of carbon in the soil and increase the amount of carbon dioxide discharged by decomposers.
One of the ways to manage the garden is to utilize mulch, the mulch minimizes the contact between the soil and the organic matter so that the species will consume more time to dissociate it. The mulch will decompose and its nutrients will be discharged to the soil, however, it takes place very gradually, and enhances the organic matter in the soil.
If the mulch is left in the garden for a year, then the soil will be conserved and supplied with nutrients and this process will retain carbon in that garden. The sources of mulch can be leaves, grass, straw, or composted garden waste.
