In ecology, biomass refers to the accumulation of life that is possibly living matter. Ecology (from Greek grc οἶκος oikos, "house(hold" and grc -λογία -logia) is the scientific study of Life is a state that distinguishes Organisms from non-living objects such as non-life and dead organisms being manifested by growth through Metabolism [2] That is, it is the total living biologica (usually measured per square metre or square kilometre). This means that only 30% of the weight of any creature is counted, the rest being water.
The most successful animal, in terms of biomass, is the Antarctic krill, Euphausia superba, with a biomass of probably over 500 million tons, roughly five times the total biomass of humans. Antarctic krill ( Euphausia superba) is a Species of Krill found in the Antarctic waters of the Southern Ocean. Human beings, humans or man (Origin 1590–1600 L homō man OL hemō the earthly one (see Humus The entire earth contains about 75 billion tons of biomass, or 0. 00000000126% of the total mass of the Earth. EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001 Humans comprise about 100 million tons (0. 13%) of the Earth's biomass[3], domesticated animals about 700 million (1. Domestication (from Latin domesticus) refers to the process whereby a Population of Animals 0%), and crops about 2 billion tons or 2.

The total biomass of bacteria is estimated to equal that of plants [4].
Biomass may also be a measure of the dried organic mass of an ecosystem. An ecosystem is a natural unit consisting of all plants animals and micro-organisms( Biotic factors in an area functioning together with all of the non-living physical ( As the trophic level increases, the biomass of each trophic level decreases. In Ecology, trophic dynamics is the system of trophic levels ( Greek trophē, food which describe the position that an organism occupies That is, producers (grass, trees, scrubs, etc. An autotroph (from the Greek autos = self and trophe = nutrition is an Organism that produces complex Organic compounds from simple ) have a much higher biomass than animals that consume them (deer, zebras, insects, etc. A heterotrophs, or chemoorganotrophy ( Greek heterone = (another and trophe = nutrition is an Organism that requires ). The level with the least biomass is the highest predators in the food chain (foxes, eagles, etc. ) Biomass is also influenced by net primary productivity (NPP).
