Question

Explain standing crop in an ecosystem. Draw a pyramid of biomass when a small standing crop of phytoplanktons supports a large standing crop of zooplankton in the sea.

Answer 1

Each trophic level has a certain mass of living material at a particular time called as the standing crop. The standing crop is measured as a mass of living organisms or the number in a unit area. The biomass of a species is expressed in terms of fresh or dry weight.

Inverted pyramid of biomass is a small standing crop of phytoplanktons support a large standing crop of zooplanktons.

Answer 2

Pyramids Of Biomass  

Explanation:

1. A standing crop is a giving material at a particular time.
2. A pyramid is a standing crop that indicates how much biomass is present in each trophic lable at any one time. only about 10% energy available within one trophic label is transferred to the organism at the next tropic label.
3. Pyramids of biomass is always inverted such as phytoplanktons, Zooplankton, and fishes.
4. In a terrestrial ecosystem, the maximum biomass occurs in producers and there is a progressive decrease in biomass from the lower to higher trophic levels.  
5. The pyramids of biomass In a terrestrial ecosystem is upright.
6. It pyramids represented the amount of potential food available at each trophic label.
