Biotic Component > Producers

The living organisms of an ecosystem, including producers, consumers and decomposers, which interact with one another and maintain ecological balance, are called biotic components.

Organisms that manufacture their own food from simple inorganic substances using sunlight through photosynthesis are called producers.

• Biotic components encompass all living organisms in an ecosystem – namely producers, consumers, and decomposers – that interact to sustain ecological balance.
• Producers are organisms capable of manufacturing their own food from simple inorganic substances, serving as the foundational energy source for the ecosystem.
• Terrestrial producers (such as trees, shrubs, and grasses) drive land-based ecosystems by synthesising food using sunlight through photosynthesis.
• Aquatic producers (such as phytoplankton, algae, and aquatic plants like Hydrilla) perform the same photosynthetic role within water-based ecosystems.
• Chemosynthetic producers (such as sulphur bacteria) operate in extreme habitats like deep-sea vents, uniquely utilising chemical energy instead of sunlight to produce food.
