Nuitrition in plants Nutrition is an essential part of life for all living organisms. Autotrophs and heterotrophs obtain their nutrition in different ways. Autotrophs, such as plants, obtain their nutrition by photosynthesis, while heterotrophs, such as animals, must consume other organisms to obtain their nutrients. Photosynthesis is the process in which plants use light energy from the sun to turn carbon dioxide and water into glucose and oxygen. This process provides the necessary energy for plants to grow and thrive. Heterotrophic organisms rely on other sources of nutrition such as other plants or animals to get the nutrients they need to survive. Both autotrophic and heterotrophic modes of nutrition are essential for sustaining life on Earth. Types of nutrition Nutrition is the process of obtaining energy and essential nutrients from food. It is an important factor in the growth and development of living organisms. Nutrition can be divided into two main types: autotrophic
