Explain energy flow in ecosystem
Answers
Answer:
Energy flow is the flow of energy through living things within an ecosystem. All living organisms can be organized into producers and consumers, and those producers and consumers can further be organized into a food chain. Each of the levels within the food chain is a trophic level.
Answer:
1. Energy flow in the ecosystem occurs by the food chain from producer to consumers.
2. The producers synthesize food and stores the energy from the sun. E.g., green plants. They are called autotrophs.
3. Then energy is transferred from producers to consumers, called heterotrophs.
4. Primary consumers are called herbivores.
5. Herbivores are eaten up by secondary consumers, called carnivores.
6. Thus, energy is transferred within an ecosystem by the prey-predator relationship.
7. At the apex of the food chain omnivores (thrives on autotrophs as well as heterotrophs) are present.
8. When the producers and consumers of the food chain are dead, their energy is utilized by detrivores (organisms feeding on dead bodies). E.g., termites, vultures, etc
9. The decomposers break down dead organisms and return the nutrients to the soil. They are known as saprophytes. E.g., bacteria, fungi.
