About 80% of the air in our atmosphere is made of nitrogen. All living things need nitrogen; it is a key element in DNA, RNA, and proteins. Your body gets the nitrogen it needs from food. But how does the nitrogen get from the air into the food that we eat? In order for plants and animals to be able to use nitrogen, N2 gas must first be converted to more a chemically available form. Review the picture of the nitrogen cycle.
In order for plants and animals to be able to use nitrogen, N2 gas must first be converted to more a chemically available form. Review the picture of the nitrogen cycle. One type of organism is responsible for "fixing" nitrogen so other organisms can use the element. What organism is this?

Need this store of protein: 

The seed consists of three components: embryo, endosperm (sometimes perisperm), and seed-coat. Both endosperm and embryo are the products of double fertilization, whereas the seed-coat develops from the maternal, ovular tissues. The seed habit is a significant advancement in the evolution of higher plants.

Answer with explaination:

 An attempt to document and identify all biological species living in some defined area, usually a park, reserve, or research area. The numbers of species on earth is rapidly diminishing, knowing what species are around will give us an idea of what we're losing, how our actions are affecting the environment.
