Question

Which of the following is an example of a biotic component in an ecosystem?

Options

• Minerals and atmospheric gases

• Sunlight and temperature

• Green plants, algae, and cyanobacteria

• Soil and water

Answer 1

Biotic components are living organisms within the ecosystem. Green plants, algae, and cyanobacteria are examples of producers, which are biotic components that synthesize food via photosynthesis. In contrast, abiotic components such as sunlight, temperature, soil, water, and minerals are non-living physical and chemical factors.
