How is sun the ultimate source of biomass?

Answer 1

Common sources of biomass are (1) agricultural wastes, such as corn stalks, straw, seed hulls, sugarcae leavings, bagasse , nutshells, and manure from cattle, pultry , and hogs; (2) wood materials, such as wood or bark, sawdust , timber slash, and mill scrap; (3) municipal waste, such as waste paper and yard clippings; and (4) energy crops, such as poplars, willows, switchgrass, alfalfa , prairie bluestem, corn (starch) , and soybean (oil).

Answer 2

With very minor exceptions (thermal vent organisms) the sun is the ultimate source of energy for living organisms, because green plants derive their energy from sunlight, and everything else derives its energy either from eating those green plants, or from eating other organisms which eat green plants (or you can have a sequence of whatever length, organisms that eat organisms that eat organisms etc., that eat green plants).

Answer 3

The sun is the ultimate source of biomass because it provides the energy needed for photosynthesis. Plants absorb sunlight and convert it into chemical energy through photosynthesis, which is then transferred through the food chain to support the growth of all living organisms on Earth. Without the sun's energy, the process of photosynthesis would not occur, and biomass production would not be possible.

Answer 4

Biomass doesn't come from the sun, but it does get its energy from the sun.
