What is biomass distribution?
(C) Distribution of biomass between producers (autotrophs, mostly photosynthetic) and consumers (heterotrophs without deep subsurface) in the terrestrial and marine environments. The size of the bars corresponds to the quantity of biomass of each trophic mode.

What percentage of biomass is humans?

What percentage of biomass is insects?
Of the 550 gigatons of biomass carbon on Earth, animals make up about 2 gigatons, with insects comprising half of that and fish taking up another 0.7 gigatons. Everything else, including mammals, birds, nematodes and mollusks are roughly 0.3 gigatons, with humans weighing in at 0.06 gigatons.
How do humans affect biomass production?
According to the a 2011 biomass census compiled by Vaclav Smil, human activity over the last 5,000 years has reduced total global biomass by about 50 percent, from over 1,000 Gigatons of Carbon at the dawn of agriculture to the current 545 GtC. The decline, through wild harvesting and habitat conversion, continues.
What are types of biomass?
Biomass feedstocks include dedicated energy crops, agricultural crop residues, forestry residues, algae, wood processing residues, municipal waste, and wet waste (crop wastes, forest residues, purpose-grown grasses, woody energy crops, algae, industrial wastes, sorted municipal solid waste [MSW], urban wood waste, and …
