However, for some species, such shark - osmoconformers - this is false: they are affected by the salinity. in general I would conclude that This is false: the marine salinity DOES affect the fish (and other organisms) living there.
Answer: Organisms interact with the nonliving parts of their ecosystem to get food, energy, and other resources that help them survive. The nonliving parts of the ecosystem are called abiotic factors. Sunlight: Sunlight provides energy that plants and certain bacteria absorb to make their own food.
The most common phenotype or allele for a gene in a population is referred to as the wild-type. The wild type denotes to the phenotype of the classic form of a species as it arises in Mother Nature. In the beginning, the wild type was inattentive as a creation of the standard normal allele at a locus in difference to that created by a non-standard mutant allele.
