Question

The creating force of any ecosystem is

• A. Organic fuels, carbohydrates
• B. Biomass
• C. Solar energy
• D. Producers

Answer 1

The correct option is C Solar energy

Nearly all of the energy, that drives ecosystems ultimately comes from the sun.

Solar energy, which is an abiotic factor, enters the ecosystem through the process of photosynthesis. The organisms in an ecosystem, that capture the sun's electromagnetic energy and convert it into chemical energy are called as producers.

Producers include all of the green plants and some bacteria and algae. The primary consumers exclusively feed on producers. They are known as herbivores. Primary consumers only obtain a fraction of the total solar energy about 10% captured by the producers they eat.

The other 90% is used by the producer for growth, reproduction, and survival, or it is lost as heat. Primary consumers are eaten by secondary consumers. Secondary consumers are eaten by tertiary consumers.
