What does biomass refer to in an ecological context?

• A. The total mass of organic material in a defined area
• B. The energy stored in consumers
• C. The efficiency of energy transfer
• D. The number of species in an ecosystem

Answer: (A)

Biomass refers to the total mass of organic material in a defined area, particularly in the context of living organisms within an ecosystem. It represents the accumulated mass of all living (or recently living) biological material, which is primarily made up of plants and animals. In ecology, understanding biomass is crucial because it provides insights into the flow of energy through an ecosystem. Higher biomass in a particular area typically indicates a greater availability of energy for consumers within that ecosystem, as plants convert sunlight into organic matter through photosynthesis. The concept of biomass is essential for studying ecosystem productivity, as well as for assessing environmental health and sustainability. By measuring the biomass of a defined area, ecologists can gauge the amount of energy available to different trophic levels, which helps illustrate how energy flows and is utilized within food webs.
