Nutrition is the process by which living organisms obtain and utilize nutrients for energy, growth, and maintenance. Different organisms have different modes of nutrition. Autotrophs, like plants, produce their own food through photosynthesis, using sunlight, water, and carbon dioxide. Heterotrophs, like animals, obtain their food by consuming other organisms. Understanding these nutritional strategies is crucial for comprehending the interconnectedness of ecosystems and the flow of energy through them.
