If you consider the all the living things found in an
ecosystem, as a pyramid of biomass, then photosynthetic organisms(producers) would be
found on the bottom of the pyramid. This indicates that this trophic level contains the
largest amount of biomass. All other levels above this one, rely on the previous level
before it. Therefore, there will always be a greater amount of autotrophs(green plants)
because due to photosynthesis, they are capturing sunlight directly and converting this
energy into the chemical energy of glucose. As herbivores, in the next level of the
pyramid eat the plants, they will obtain food energy. However, their biomass will be
less because they are feeding on the plants below which have a greater amount of
organisms. Also, herbivores lose energy when some of it is converted to
heat.

Relate the term “Biomass” to a photosynthetic organism. How does the organism produce more biomass?
