the answer is A. Individual
The units used by the biomass pyramid are individual units. Because the biomass pyramid calculates mass and sequences from each individual living creature ranging from large to small such as whales, elephants, cats. chicken, rat, ant, to bacteria.
<h2>Further explanation
</h2>
The biomass pyramid illustrates the total weight of organisms that occupy each trophic level. To measure biomass at each trophic level, the average weight of organisms at each level is measured then the number of organisms at each level is estimated.
In ecology, biomass is the mass of biological organisms living in an area or ecosystem at a certain time. Biomass in ecology can refer to the biomass of species, which is the mass of one or more species, or community biomass which is the mass of all species in a community.
Biomass is grouped into four groups:
- Mainland Biomass
- Ocean Biomass
- Bacterial Biomass
- Global Biomass
