Energy Flow in Ecosystems: Energy Flow In Ecosystems Worksheet Pdf Answers

Energy flow in ecosystems refers to the transfer of energy from one organism to another within an ecosystem. It begins with the capture of sunlight by plants, known as producers, through photosynthesis. This energy is then passed on to consumers, which include herbivores, carnivores, and omnivores, and ultimately to decomposers.

Energy flows through different trophic levels, which represent the feeding relationships within an ecosystem. Producers occupy the first trophic level, followed by primary consumers (herbivores), secondary consumers (carnivores), and tertiary consumers (top predators). At each trophic level, a significant portion of the energy is lost as heat, resulting in a decrease in the amount of energy available at higher trophic levels.

Decomposers, such as bacteria and fungi, play a crucial role in energy flow by breaking down dead organisms and returning nutrients to the ecosystem. This process releases energy that can be utilized by other organisms.
