Is the pyramid of biomass always upright in an aquatic ecosystem and how is a pyramid of biomass connected to an ecosystem?
The pyramid of biomass is not always upright in an aquatic ecosystem; it can be either upright or inverted, depending on the specific characteristics of the ecosystem and the dynamics of the food web within it. Let's explore the concept of the pyramid of biomass and its connection to an ecosystem:
It's important to note that the shape of the pyramid of biomass can vary depending on specific ecological conditions, nutrient availability, environmental factors, and the complexity of the food web within an ecosystem. In some cases, the pyramid of biomass may even be irregular or diamond-shaped, reflecting the unique interactions between different organisms and the complexity of energy flow within the ecosystem.
The biomass pyramid of aquatic ecosystem is inverted. Here the biomass of primary producers is much less than the zooplanktons, which is less than the small fish and the big fish having the maximum biomass. The pyramid of biomass in the sea is inverted because the amount of biomass is least at the base of the pyramid and the amount of biomass is maximum at the apex of the pyramid. The pyramid of biomass in sea is generally inverted because the biomass of fishes far exceeds than that of phytoplanktons. Most pyramids are larger at the bottom, but marine biomass pyramids are often inverted. This is because the producers are very small and have limited mass. They also reproduce and die quickly, so there is less biomass at any given time compared to consumers. The energy pyramid is always upright because energy is constantly lost as heat when it travels from one trophic level to the next. This heat escapes into the atmosphere and is never returned to the sun.Aquatic biomass is a reversal of terrestrial biomass, can increase at higher trophic levels. In the ocean, biomass pyramid is an inverted. In particular, the biomass of consumers is larger than the biomass of primary producers. A biomass pyramid is the representation of total living biomass or organic matter present at different trophic levels in an ecosystem. Biomass is calculated as the mass of living organisms present at each trophic level in a given sample size. Pyramid of biomass shows the amount of biomass at each trophic level in an ecosystem while pyramid of energy shows the flow of energy from one trophic level to the next in an ecosystem. This is the key difference between pyramid of biomass and pyramid of energy. Energy pyramids are used to show how much energy is available in each of the different trophic levels. Because the amount of energy is proportional to the amount of matter in an ecosystem, these pyramids can also show how much matter or biomass is available in each trophic level. A pyramid of biomass is a graphical portrayal of biomass present in a unit of the territory of different trophic levels. In addition, it displays the linking among biomass and trophic level estimating the biomass available in each trophic degree of an energy network at a given time.
