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.

B I don't belive plant life is that important to this question
the fourth option
Charles's law states that the volume increases with the temperature so the fourth option should be correct
Answer:
B
Explanation:
By combining drip and flood irrigation. Drip irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. The goal is to place water directly into the root zone and minimize evaporation.
Flood irrigation is a practice in which an entire field is covered with water, while furrow irrigation adds water through furrows adjacent to crop beds. In flood irrigation systems, soils experience highly anoxic periods which promote denitrification processes.
Answer:
Proton and neutron.
Explanation:
The atoms consists of three sub atomic particles - proton electron, and neutron. The proton and neutron are present inside the nucleus and electrons revolve around the nucleus.
The number of proton is equal to the number of electron in the neutral stage of atom. The atomic mass of an element can be calculated by the sum of number of neutrons and the number of protons. Hence, the subatomic particle - proton and neutron contribute to the mass of hydrogen.
Thus, the correct answer is option (b) and (d).
