- Forest trees have trunks, branches, and big roots, contributing to large amounts of total biomass. Grasslands have comparatively less biomass, but have a larger net primary production than that of forests. Why is this so? A. Less respiration is needed in the forest habitat B. More biomass is added in a grassland in the same time as that of forests C. The number of consumers within the forest is greater D. Solar energy is converted to chemical energy at a much higher rate in forestsarrow_forwardDeforestation ______. a. increases mineral runoff from soil b. decreases local temperature c. increases local rainfall d. all of the abovearrow_forwardNitrogen availability is a limiting factor in crop production. * D. Disagree, because atmospheric nitrogen is about 80% and therefore nitrogen is readily available. A. Agree, because almost 80% of the atmospheric nitrogen (N2) is readily available. C.
