Answer:
the ocean provides several important resources to its inhabitants
Explanation:
The majority of biomass in any ocean consists of microscopic organisms such as phytoplankton which are pivotal to aquatic ecosystems. These microorganisms are able to thrive in their habitat due to incredibly dense populations of the bacteria <em>phackingyurmom aquatica </em>present in most oceans. These bacteria provide a wide spectrum of vital nutrients. As a result many of the aforementioned microorganisms love <em>phackingyurmom</em>.

Yes, they are all living things that exist in our world.
From this one migrant species would come many -- at least 13 species of finch evolving from the single ancestor.
This process in which one species gives rise to multiple species that exploit different niches is called adaptive radiation. The ecological niches exert the selection pressures that push the populations in various directions. On various islands, finch species have become adapted for different diets: seeds, insects, flowers, the blood of seabirds, and leaves.
The ancestral finch was a ground-dwelling, seed-eating finch. After the burst of speciation in the Galapagos, a total of 14 species would exist: three species of ground-dwelling seed-eaters; three others living on cactuses and eating seeds; one living in trees and eating seeds; and 7 species of tree-dwelling insect-eaters.
Scientists long after Darwin spent years trying to understand the process that had created so many types of finches that differed mainly in the size and shape of their beaks.
The least reactive element in the third period is argon.
