Energy flow in ecosystem
What is energy flow?
Food’s chemical energy is the primary source of energy for all living beings. This energy is sent down the food chain to various trophic levels.
The energy flow in ecosystem
One of the primary variables that support the survival of such a large number of organisms is the energy flow in ecosystem. Solar energy is the principal source of energy for practically all species on the planet. It’s amusing to learn that we only receive about half of the sun’s effective radiation on Earth. When we talk about effective radiation, we’re talking about the kind of light that plants can employ to perform photosynthesis.
The earth’s atmosphere normally reflects the majority of the sun’s radiation that falls on it back into space. The Photosynthetically Active Radiation is the name given to this effective radiation (PAR).
Overall, earth obtains roughly 40 to 50 percent of our energy from Photosynthetically Active Radiation, with plants using just 2-10 percent of it for photosynthesis. As a result, this percentage of PAR benefits the entire planet because plants are the ecosystem’s producers, and all other organisms are either directly or indirectly reliant on them for existence. The energy flow in ecosystem is transferred through the food chain and web. Plants, as producers, collect sunlight through their chloroplasts and convert a portion of it into chemical energy through the process of photosynthesis.
