Which can explain the energy stored in one ecosystem?
Food web. Hint: Pyramid of energy is the stored biomass in an ecosystem of each trophic level. The energy of each level is stored as biomass. Biomass decreases at each ascending level of the food chain.
What is the main source of energy in an ecosystem Why?
The primary source of energy for almost every ecosystem on Earth is the sun.
Where and how does energy enter an ecosystem?
Energy enters the ecosystem via sunlight as solar energy. Primary producers (a.k.a., the first trophic level) turn that solar energy into chemical energy via photosynthesis. Common examples are land plants, photosynthetic bacteria and algae.
Where does the rest of the energy go?
The rest of the energy is passed on as food to the next level of the food chain. The figure at the left shows energy flow in a simple food chain. Notice that at each level of the food chain, about 90% of the energy is lost in the form of heat.
How is energy lost in a food chain?
Not all the energy is passed from one level of the food chain to the next. About 90 per cent of energy may be lost as heat (released during respiration), through movement, or in materials that the consumer does not digest. The energy stored in undigested materials can be transferred to decomposers.
In what form does energy enters and leave the ecosystem?
Energy enters and leaves the ecosystem in the form of Solar energy. Energy leaves the ecosystem through heat.
