There is a gradual decrease in number, biomass and energy of organisms from the production level to the consumer level.
1. Pyramids of Number:
It represents the number of individuals in various trophic levels of food chain per unit area at any given time
2. Pyramid of Biomass:
ADVERTISEMENTS:
The word biomass means the total weight of living matter per unit areas at a given time. In every ecosystem, the biomass decreases from the producer’s level to the consumer level.
Grass → Mouse → Snake → Hawk
Plants Rabbit Fox → Lion
3. Pyramid of Energy:
In every ecosystem, the energy flows from the producer level to the consumer level. At each trophic level substantial portion of energy is lost. Hence the amount of energy decreases from the producer level to the consumer level.
