Day 8-
Rachel and I got to talking and we discovered that the nitrogen cycle is very important to organisms in a tropical rainforest.
Plants and animals need nitrogen for growth and reproduction. Herbivores specifically need it to be able to contain amino acids, nucleic acids, and proteins.
 Although 78% percent of gas in the atmosphere is nitrogen, this nitrogen is not usable. Nitrogen has to be fixed before it can be usable. There are multiple ways it can be fixed.
 In a rainforest there are plants that have nitrogen-fixing bacteria on their roots.
Another way to make nitrogen usable is from lightning. When lightning strikes it breaks nitrogen molecules which allows for atoms to combine with oxygen.
Both of these ways make nitrogen fixed and usable for plants and animals.
