The plants and other green organisms produce the food for the web. But they need to use some of the energy for growth and for reproduction.
That leaves about 10% for the next level. That level also needs energy for growth and reproduction, so that leaves 1% for the third level.
Since this works this way, each level is smaller and smaller. The number at each level competes for food with the others in that level.
So there is only one type of hawk on the top level, for example. The larger number of producers (first level), the more species on the next levels.
If the first level is low in numbers, there will be fewer in the levels above. Some poor ecosystems have only 3 levels. The very best have 5.
It starts with the light energy from the Sun, used by the plants/producers/organisms containing chlorophyll through photosynthesis to make food.
Plants capture solar energy from photosynthesis
The transfer of energy in an ecosystem is what is shown in a food chain. The 1st level consumer eats the producer. The 2nd level consumer eats the 1st level consumer and so on.
Energy is transferred by oxidation reduction reactions.in this energy is stored in form of bonds when these bonds break down it transfers in ecosystem and help in body activities...........
by the by cycle.
by energy transfer
Energy must be transformed within ecosystems so that it is made available to other organisms. Energy is produced by producing organisms at the lowest trophic level, and then moves up to higher trophic levels to other consuming organisms.
The producers have a limited source of energy
Ecosystems do not have to be completely the same throughout, they can have regional variations. So an ecosystem within an ecosystem is much like a neighborhood within a city.
actually, i dont know but i guess that they get energy from ..........

the food chain
Energy must be transformed within ecosystems so that it is made available to other organisms. Energy is produced by producing organisms at the lowest trophic level, and then moves up to higher trophic levels to other consuming organisms.
Everything from climate to the food chain affects the efficiency of energy transfer in an ecosystem. The smallest changes, such as an animal becoming extinct, can have a very dramatic impact on the energy within an ecosystem.
Energy is transferred to, within and from living organisms by light, heat, movement, electricity and chemical changes.

it begins the energy in the food chain of an ecosystem. It goes from the sun to the producers to the consumers
The producers have a limited source of energy
Heat energy is transferred from warmer objects to cooler objects.
