Biomass refers to the total mass of living organisms within a specific area or ecosystem. It includes all living organisms like plants, animals, and microorganisms. Biomass can be measured in terms of weight or energy content.
A. How much an ecosystem weighs: This is incorrect. Biomass does refer to the weight of living organisms in an ecosystem, but it includes all organisms, not just the ecosystem itself.
B. How much energy is made by the producers in a certain area: This is the correct definition. Biomass represents the energy stored in the organic matter produced by plants (producers) through photosynthesis. This energy is then transferred through the food chain to other organisms.
C. How much energy is made by the consumers in a certain area: This is incorrect. Biomass does not refer to the energy produced by consumers (animals that eat other organisms) in an area but rather to the energy produced by the producers.
