Plants need nitrates to develop green leaves. Nitrogen, potassium and phosphorus are the three major nutrients plants need to grow successfully. In particular, nitrogen is responsible for foliage development. Plants use nitrogen in the form of nitrates, which is nitrogen mixed with oxygen. They usually absorb nitrates from the soil.
Animals get nitrogen by eating plants and other animals. Just like animals, plants require nitrogen to grow and survive. But they do not get nitrogen by consuming proteins like animals do. Plants get nitrogen from water and from the soil. They get nitrogen by absorbing it in the form of nitrates and ammonium.Nitrates are the major source of nitrogen for aquatic plants.nimals get nitrogen by eating plants and other animals.
