Nitrogen fixation<span>. </span>Nitrogen fixation<span> is a </span>process<span> by which </span>nitrogen<span> in the Earth's atmosphere is converted into ammonia (NH</span>3<span>) or other molecules available to living organisms. Atmospheric </span>nitrogen<span> or molecular dinitrogen (N</span>2<span>) is relatively inert: it does not easily react with other chemicals to form new compounds</span>
When the ocean produces oxygen through the plants (phytoplankton, kelp, and algal plankton) that live in it. These plants then produce oxygen as a byproduct of photosynthesis, which is a process that converts carbon dioxide and sunlight into sugars that the organisms can use for energy then and later on.

Biodiversity occurs within self sustaining ecosystems
The elephant cell will have 20 chromosomes.
Cells undergo interphase before getting to the mitotic phase. At the S phase of the interphase, the amount of DNA in the cell is double by replication. However, the number of chromosomes remains intact.
Thus, the cell gets to the mitotic phase with the same number of chromosomes that is usually present in normal vegetative cells of the animal.
