Question

An ecological pyramid of biomass is a representation of the ecosystems :

• A. Energy flow through each trophic level
• B. Tissue at each trophic level
• C. Populations in each food web
• D. Biological material in relation to abiotic material

Answer 1

The correct option is B Tissue at each trophic level

A biomass pyramid is the representation of total living (cell or tissue) biomass or organic matter present at different trophic levels in an ecosystem.

A biomass pyramid is a diagram that compares the biomass of different trophic levels within an ecosystem. It shows the mass of producers that are needed to support primary consumers, the mass of primary consumers required to support secondary consumers.

A biomass pyramid shows the total mass of the organisms that each trophic level occupies in an ecosystem. This can be referred to as tissue mass present at each trophic level.

So, the correct option is, 'tissue at each trophic level'.
