A potential source of nitrogen in a sandy soil environment might be the bacterium, Rhizobium, which inhabits the root nodules of leguminous plants. Which of these statements is true, and should prevent Rhizobium or other root-inhabiting nitrogen-fixers from contributing nitrogen to the soils for bryophytes?

A) Mosses evolved before there were substantial amounts of nitrogen in Earth's atmosphere.
B) Mosses have no roots.
C) Moss gametophytes lack stomata.
D) Among land plants, only legumes are known to establish symbiotic relationships with members of other kingdoms.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
