It starts with the sun then autotrophs, or organism that makes its own food, such as grass, uses the energy from the sun to make food. Then heterotrophs, or organisms that can't make its own food, such as a zebra obtains energy by eating the grass and another heterotroph such as a lion obtains energy by feeding on the zebra.

Its food chain
The flow of energy through an ecosystem is described as one-way or linear. This means that energy enters the ecosystem and passes through it without being recycled. Energy enters in the from of light (via photosynthesis) and leaves as heat. Heat is not used as a source of energy by living organisms. Chemical compounds can be recycled, so their movement is cyclical in an ecosystem. The same atoms are used over and over again, so your body will contain atoms that were in the bodies of dinosaurs, for example.

The bottom layer of pyramid that represents ecosystem producers is the ecological pyramids. The top layers represent consumers. In the energy pyramid the bottom levels have more energy than the top levels.
thank u
The typical movement of energy through an ecosystem is upward. This means that food flows through the different animals that eat each other.
Its food chain
An example of the transfer of energy is the food chain. This is different from movement of basic elements in the ecosystem because energy gets used, not just moved.
Energy is not recycled, it flows in and out in a unidirection. Chemical energy enters as light energy and is produced by producers and leaves the ecosystem as heat.
How does energy flow through an ecosystem?

how about food chain it hapens every hr you know
two major process 1 = cycling of nutrient 2= chemical energy (food)
