This is a typical grassland food web. it is also a small picture of an important cycle on earth: the carbon cycle. describe how the carbon gets into this food web.
a) bacteria and fungi, the decomposers, recycle carbon from dead organisms.
b) carbon is found in the grass and is passed from one level to the next in this food web.
c) all living things give off carbon dioxide as a by-product of respiration and it is released into the atmosphere.
d) plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar.

One of the newest applications of cell technology is called cybrid embryos. this process involves replacing the nuclear material of an animal cell with human nuclear material. how might this process affect public policies about research by using stem cells? the same policies and concerns about the use of human embryonic stem cells would most likely apply. the embryos would most likely be treated like traditional animal embryos and regulated accordingly. the process of forming cybrid embryos would most likely be banned by government regulators. the embryos would be treated as regular cells because they are not fully human in origin.
