flow of energy quick check
answers know
The flow of energy refers to the transfer of energy from one organism to another in an ecosystem. It typically starts with the sun, which is the primary source of energy for most ecosystems. The sun's energy is captured by plants through photosynthesis, converting it into chemical energy.
The plants, also known as producers, are then consumed by primary consumers, such as herbivores. These herbivores obtain energy by consuming the plants.
Next, energy flows to secondary consumers, which are typically carnivores that feed on herbivores. Secondary consumers obtain energy by consuming primary consumers.
Finally, energy is transferred to decomposers, which break down dead organic matter and return nutrients to the ecosystem. Decomposers, such as bacteria and fungi, release energy locked in dead or decaying organisms.
Overall, the flow of energy moves through different trophic levels in an ecosystem, starting with the sun and ending with decomposers.
