Which of the following ecological pyramids is generally inverted

In an aquatic ecosystem, the pyramid of biomass is generally inverted. The gross primary productivity of an ecosystem is tons organic matter and amount used in respiration is 50 tons. Calculate the net primary productivity of the ecosystem. Xerarch succession - plant succession starting bare ground or rock, pioneer species are lichens and mosses.

Pyramid of biomass in a sea. Pyramid of numbers in grassland. Pyramid of energy. Pyramid of biomass in a forest. Define ecological pyramids.

Ecological pyramids are the way to show the structure of ecosystems, the term was first described by Charles Elton in s in the pioneering studies of ecosystem. In his studies, he noted that larger organisms higher in food chains were less abundant than smaller ones in lower trophic levels. Ecological pyramids show the relative amounts of various parameters such as number of organisms, energy, and biomass across trophic levels. They can also be called as trophic pyramids or energy pyramids. A graphical representation of trophic structure and function of an ecosystem, starting with producers at the base and successive trophic levels forming the apex is called as an ecological pyramid.

All living things require energy in one form or another. Energy is required by most complex metabolic pathways often in the form of adenosine triphosphate, ATP , especially those responsible for building large molecules from smaller compounds, and life itself is an energy-driven process. Living organisms would not be able to assemble macromolecules proteins, lipids, nucleic acids, and complex carbohydrates from their monomeric subunits without a constant energy input. It is important to understand how organisms acquire energy and how that energy is passed from one organism to another through food webs and their constituent food chains. Food webs illustrate how energy flows directionally through ecosystems, including how efficiently organisms acquire it, use it, and how much remains for use by other organisms of the food web. Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously living organisms by heterotrophs.
