Energy Pyramid and the 10% Law: a 3D model for Class 10 Science, covering Green plants capture about 1% of the sunlight that falls on their leaves and turn it into food energy., A food chain is the line along which energy passes: grass → grasshopper → frog → snake → eagle., Each step of a food chain is a trophic level: producers, then first, second and third-level consumers., The 10% law: only about 10% of the energy at one level reaches the next; the rest is used up or lost as heat., Because so little passes on, food chains rarely have more than three or four steps..

Green plants capture about 1% of the sunlight that falls on their leaves and turn it into food energy.
A food chain is the line along which energy passes: grass → grasshopper → frog → snake → eagle.
Each step of a food chain is a trophic level: producers, then first, second and third-level consumers.
The 10% law: only about 10% of the energy at one level reaches the next; the rest is used up or lost as heat.
Because so little passes on, food chains rarely have more than three or four steps.
Energy flows one way, from the sun to producers to consumers; it never returns to the sun.
Many food chains cross and join into a food web, because most animals eat more than one kind of food.
Removing one species disturbs the web: its prey increase and its predators must turn to other food.
