This is described as the location of an organism withinside the meals chain. Energy waft withinside the atmosphere includes 10% of the electricity withinside the decrease trophic level being transferred to the following trophic degree.
- In this situation grass belongs to the primary trophic degree.
- Energy of grass (degree 1)=250c Kcal Level 2 = 10/100 * 25000Kcal = 2500 Kcal.
- Level 3 = 10/100 * 2500Kcal = 250Kcal
- Level 4=10/100*25=2.5 Kcal.
