Producers - Biotic Components
Producers also called autotrophs are largely green plants that can make food from simple inorganic materials. Food refers to complex organic compounds such as carbohydrates, fats and proteins. Green plants accomplish food making through the process of photosynthesis. In this process, green plants use carbon dioxide, water and some minerals, to produce carbohydrates first and later various other-organic compounds such as fats and proteins. Oxygen is given off by plants as a by product of photosynthesis. During photosynthesis, radiant energy of sunlight is converted into chemical energy and is stored in the chemical bonds of the compounds made by the plants.
