Question

On the basis of biomass draw a pyramid of terrestrial ecosystem

Answer 1

Hello!!

Pyramid of biomass for terrestrial ecosystems (grasslands, forests) the biomass generally decreases at each higher trophic level from plants via herbivores to carnivores. This is evident from the fact that the terrestrial producers'

Thanks!

Answer 2

Pyramid of biomass:

• A biomass pyramid is the model of cumulative living biomass or organic material existing at various trophic levels in the ecosystem.
• Biomass is assessed as the abundance of habitation organisms surviving at every trophic level in a provided specimen size. It can be illustrated as dry weight in grams or kilo calories per unit territory. A bomb calorimeter is adopted to analyze biomass.

• The trophic level is the special territory where a habitation organism existed in a food cycle.
• In a biomass pyramid, the producers' primary trophic level is at the bottom, accompanied by herbivores named primary consumers and then carnivores are understood as secondary consumers and tertiary consumers at the prime.
• The biomass pyramid demonstrates the advancement of energy from producers to dependents. So it indicates an understanding that only 10 per cent of the total energy assigns is transferred to the subsequent trophic level and the rest is either used for metabolic systems or excreted out.
