The radiant energy of the sun enters into the ecosystem through the photosynthetic activity of plants (producers). Ultimately disappears in space as heat energy, which never returns to the source. This phenomenon is referred to as the flow of energy which is the unidirectional flow of energy governed by different biogeochemical cycles.
In a difficult-to-digest nut shell, energy transfer through an ecosystem is restricted by the ability of primary producers to convert solar energy, and the ability of consumers to take in the energy they obtain as biomass. Ultimately, only 10 percent of energy is transferred from one trophic level to the next.
Energy flow in an ecosystem is defined as the movement or transfer of energy from one trophic level to another in an ecosystem. The energy that is passed is in the form of chemical energy. Energy flow is the phenomenon that is responsible to sustain life on this planet. All the biotic components in this ecosystem need energy for their survival.
The sun is the main source of energy in our ecosystem. But less than half of the sun’s energy is used by plants for photosynthesis i.e. 50% of this energy is photosynthetically active radiation (PAR). Plants convert radiant energy to fixed energy and pass it on to other organisms.
Energy enters ecosystems as sunlight and is transformed into usable chemical energy by producers such as land plants, algae and photosynthetic bacteria. Once this energy enters the ecosystem via photosynthesis and is converted into biomass by those producers, energy flows through the food chain when organisms eat other organisms.
Describe energy relationships within ecosystems, including the fixation of solar energy by primary producers and the passage of that fixed energy through other components of the ecosystem. Explain why the trophic structure of ecological productivity is pyramid-shaped and why ecosystems cannot support many top predators.
Energy Flow and the 10 Percent Rule
Therefore, in order to sustain life, energy must be available within an ecosystem. The initial source of energy for almost every ecosystem on Earth is the sun: Solar energy is converted into biomass by primary producers and is then transferred between trophic levels from one consumer to the next up the food chain.
6 Energy Flow in Ecosystem: Energy Flow Models
The solar energy is captured by the green plants and transformed into chemical energy and bound in glucose as potential energy during the process of photosynthesis. In this stored form, other organisms take the energy and pass it on further to other organisms. The flow of energy in ecosystem follows first and second law of thermodynamics.
