Scrat [10]

Agriculture negatively affects reef ecosystems because the soil and the sea have a direct interaction of substances and minerals that can be altered with the intensification of agriculture.

<h3>What is agriculture?</h3>

Agriculture is a human activity that is based on planting seeds in the ground so that they develop and form plants that have uses such as food or others.

This is one of the oldest activities of humanity and has allowed communities to develop and create trading systems, wooden constructions, navigation, among others.

<h3>What impact does agriculture have on the reefs?</h3>

Agriculture generally takes place in coastal areas or near rivers because the composition of the soil must have certain minerals necessary for plants to grow.

Additionally, the components of the soil go underground to the sea and provide the water with different substances that contribute to marine life. However, the use of pesticides and other agricultural chemicals could reach the sea through runoff and affect the reefs.

Answer:

<u>Isotonic</u>

Explanation:

If the solute concentration of the cell and that of its surrounding medium are the same there will be no net flow of water in either directions. In this case, the external solution is said to be isotonic to the cell.
