briefly explain how water conservation helps control water pollution.
Answer:
It will reduce the cost and energy used to treat the water
Explanation:
Water conservation can help control water pollution by reducing the amount of water that needs to be treated and processed. When less water is used, less polluted water is generated from households, industries, and agricultural activities.
What is water conservation?Water conservation reduces the amount of wastewater that needs to be treated and discharged into natural water bodies, such as rivers and lakes. Additionally, conservation measures such as using low-flow fixtures, fixing leaks, and reducing water-intensive activities can help reduce the amount of energy needed to treat and transport water, which also reduces the carbon footprint and associated pollution from energy generation. Overall, water conservation is an effective way to reduce the demand for water resources and minimize the pollution that results from water use and treatment.
Hence, water conservation can help control water pollution by reducing the amount of water that needs to be treated and processed. When less water is used, less polluted water is generated from households, industries, and agricultural activities.

describe what happens to nutrients and matter in a biogeochemical cycle
Answer: Nutrients move through the ecosystem in biogeochemical cycles. A biogeochemical cycle is a circuit/pathway by which a chemical element moves through the biotic and the abiotic factors of an ecosystem. It is inclusive of the biotic factors, or living organisms, rocks, air, water, and chemicals. Energy flows through an ecosystem and is dissipated as heat, but chemical elements are recycled. The ways in which an element—or compound such as water—moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle.
Explanation:
Nutrients and matter in a biogeochemical cycle move through various spheres including the atmosphere, biosphere, hydrosphere and lithosphere.
Nutrients move through the ecosystem in the nutrient cycle or biogeochemical cycles. This cycle is a pathway by which a chemical element moves or recycles through the biotic and abiotic factors of an ecosystem.
It is inclusive of the biotic factors, or living organisms such as plants animals, and others, as well as abiotic or nonliving such as air, soil, and water.it moves through abiotic and biotic elements such as water moves through water body to the atmosphere by evaporation and moves back to earth and hydrosphere by rain and also used by living organisms.Thus, Nutrients and matter in a biogeochemical cycle move through various spheres including the atmosphere, biosphere, hydrosphere and lithosphere.
