The primary function of the chloroplasts in a plant is to convert light
from the sun into glucose and energy in a process that is known as
photosynthesis. This energy is then used by the plant cells for
incredibly important functions such as growth and repair, so the chloroplasts are amongst the most necessary parts of any plant.
Planting the same crop in the same place each year zaps nutrients from the earth and leaves soil weak and unable to support healthy plant growth. Because soil structure and quality is so poor, farmers are forced to use chemical fertilizers to encourage plant growth and fruit production.
Answer: <em>Photosy</em><em>nthesis</em>
Adenosine triphosphate (also called ATP) is used by the cell as fuel to
pump sodium out of the cell during the process of active transport. It
carries energy to the areas of the body where it is needed. It is
necessary for many of the cell's functions and is an important part of
metabolism.
The process by which <em>two species evolve</em> as a <em>response</em> to <em>changes in one another over time</em> is called, "coevolution" thus the correct answer is that it is an example of <u><em>COEVOLUTION</em></u>
