Hydrogen (H), derived almost entirely from water, is one of the 17 essential nutrients necessary for plant growth. Hydrogen, along with carbon and oxygen, are the three primary elements plant use in the largest amounts, and they perform as the building blocks for plant growth.otassium (K) is one of the essential nutrients and is taken up in significant amounts by crops. Potassium is vital to photosynthesis, protein synthesis and many other functions in plants. Itâs classified as a macronutrient, as are nitrogen (N) and phosphorus (P). Plants take up K in its ionic form (K +).
Plants are essential for any ecosystem. They provide all the energy for the ecosystem, because they can get energy directly from sunlight. They use a process called photosynthesis to use energy from the sun to grow and reproduce. They also must get nutrients from the soil.Those nutrients get into the soil when decomposer s break down waste and dead materials. Plants require space to grow and reproduce.ince all the energy in your ecosystem comes from plants, you'd better have a lot of them. There are several different kinds of plants, and not all animals can eat all kinds of plants. Grasses are only edible to herbivores. That is because the plants contain kinds of fiber that many omnivores cannot digest efficiently.
