In the primary (growing) plant cell wall, the major carbohydrates are cellulose, hemicellulose and pectin. The cellulose microfibrils are linked via hemicellulosic tethers to form the cellulose-hemicellulose network, which is embedded in the pectin matrix.

They tend to be at the start of a food chain and as energy passes through the food chain more energy is lost via respiration, faeces etc.
The answer is 150000000.
The amount of bacteria found in 100 milliliters of water will be 150000000.
Hope this helps!
The basis of classification of
Linnaeus’ system is sexual reproduction. The
only "natural" taxon in Linnaeus' system is the species. Species defined
as a population with viable, fertile reproduction are separated from
interbreeding with other species.
