What is the direction of energy flow in an ecosystem:
Correct answer: A. Always unidirectional
- A. Always unidirectional
- B. Always bidirectional
- C. In any direction
- D. Always down directional
Explanation
In an ecosystem, energy flows in a unidirectional manner, primarily from producers (such as plants) to consumers (such as herbivores, carnivores, and omnivores). This flow occurs through feeding interactions in a food chain or food web.Producers capture energy from sunlight through photosynthesis and convert it into chemical energy. This energy is then passed on to consumers as they eat the producers. Energy is gradually lost as heat at each trophic level, making it a one-way flow. Therefore, option a is correct.

About Ecosystems
An ecosystem consists of organisms interacting with one another and with abiotic factors such as light, water, soil and temperature. The topic covers populations and communities, food chains and webs, trophic levels, ecological pyramids, energy flow, nutrient cycles and ecological succession.
