2). I dont know this one. All i can say is that the protein in a grain of wheat is stored in the endosperm (storage part of a seed). Also it is stored in the form of starch.
8). Seeds are high in calories because a seed is a capsule containing the young sporophyte (plant). The young plant needs nutrients to begin to survive and grow before it can begin to photosynthesize on its own. The primary meristem (part of the plant that grows first) grows downward and begins to form the roots before the cotyledons (leaves) grow above surface. These seeds are good for humans because they are higher in fat concentration than carbos and can be used for various products like the oils.
9). Well if the temperature increased it would most likely increase the carbon cycle production. Carbon and other greenhouse gases would be more plentiful probably. Im not too sure about that one.
