Step-by-step explanation

1) Precipitation is a form of water from the atmosphere. It is a term in meteorology, and includes rain, snow, sleet, ice pellets dew, frost, and hail. These form by condensation from atmospheric water vapor, and fall under gravity. 

2) Effluent discharge is liquid waste, other than waste from kitchens or toilets, surface water or domestic sewage.

3) Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. 

4) Pollution is the introduction of harmful materials into the environment. These harmful materials are called pollutants. Pollutants damage the quality of air, water, and land.

5) Fertilizer is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply one or more plant nutrients essential to the growth of plants.

6) An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt). 

7) A habitat identifies as the array of resources, physical and biotic factors, present in an area that allow the survival and reproduction of a particular species.

8) Groundwater is the water found underground in the cracks and spaces in soil, sand and rock. 

9) Eutrophication, the gradual increase in the concentration of phosphorus, nitrogen, and other plant nutrients in an aging aquatic ecosystem such as a lake turning it into a marsh or bog.

10)  Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts.
