Energy flows through an ecosystem in one direction, which is called the food chain. It's like a pyramid. At the bottom are producers. The producers contain the most energy gotten from the sun. The next are primary consumers. Consumers obtain energy by eating the producers The next layer are the secondary consumers. There may be another layer of consumers if there is enough energy in the system.
Sunlight --> producers (100% of the energy) --> primary consumers (10%)---> secondary consumers (1%)
The decomposers return some nutrients to the system are are active at all levels.
As you move up each level the energy decreases.
For example:
Kcal = Kilocalorie (energy) For example:
Grass, a producer produces 1,000 Kcal
The grass is eaten by mice or rats, the primary consumer and gets 100 Kcal
The mice or rat are eaten by ferrets, the secondary consumer and gets has 10 Kcal.
The ferrets are then eaten by owls, the apex consumer gets 1 Kcal which may not be enough to support the owls.
It can not go any further.
In an ecosystem the energy flow depends on the 10% law.That is when energy is being transferred from producers to consumers and from consumers to herbivores carnivores ,etc. only 10 %energy stored in the previous level is taken and used by the next Trophic Level.
energy flow (E) can be defined as the sum of metabolic production (P) and respiration (R), such that E=P+R.
Below is the energy flow in the ecosystem: sun - Producer - Consumer - Decomposers - Inorganic nutrient pool.

Energy pyramid
From the sun to plants to herbivores to carnivores to the earth.
Energy in an ecosystem flows in whats called the 10% rule. Meaning, as you move up the pyramid 10% of energy is lost.
usually plants or micro-organisms with similar capabilities.
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.

How does energy flow through an ecosystem?
It shows the flow of Energy from source to usage and tracks all the losses in between.
An energy flow diagram is normally a flow diagram showing the energy gains and energy losses of a given process. This type of diagram is often used to show the efficiency of a given system or lack thereof.
