Task – Providing information about biomass; two examples of studies or research into biomass. Why is pyramid of biomass important in illustration than pyramid of numbers?
Information about biomass – A biomass is a measure of the amount of living material present such as the biomass of plants in a rainforest or of worms in the soil. Biomass is expressed in units such as gm-2. These units reflect both the mass and the size of the sample. Because the amount of water in living organisms is very variable, samples are often dried, in which case the term dry biomass is used. It is not essential, however, to use dry biomass. There are some circumstances where it is far more sensible and convenient to consider fresh or live biomass. Pyramids of biomass may be expressed in terms of biomass at each trophic level.
