NEET BIOLOGY

Detailed explanation-1: -Nutrients in streams are essential for the growth of algae and macrophytes (aquatic plants) that are an important food source for many small invertebrates and fish. The main nutrients in waterways come in the form of inorganic nutrients (simple chemicals) called nitrogen (N) and phosphorus (P).

Detailed explanation-2: -A river runs through it Nutrients, such as nitrogen and phosphorus, occur naturally, but most of the nutrients in our waterways come from human activities and sources-fertilizers, wastewater, automobile exhaust, animal waste.

Detailed explanation-3: -The essential nutrients in drinking water are calcium, magnesium, sodium and potassium. Each of these minerals raises the pH and alkalinity of drinking water, making it more healthy and alkaline.

Detailed explanation-4: -Phosphorus and nitrogen are the primary nutrients found in lakes and ponds. Aquatic plants absorb nutrients through roots down in the sediments or leaves. A reduced amount of these major nutrients is considered a limiting factor that can impact healthy plant and wildlife growth.
