The term "population" is used to describe organisms of a single species that live together in the same area. Populations combine to form communities, and communities merge with abiotic factors to create an ecosystem.Continue Reading
A population of animals is capable of breeding due to their close proximity and genetic compatibility. The combined genes from each parent dictate the characteristics of the offspring. Favorable genes that help the animal survive increase in frequency, while less desirable genes appear less frequently over time.
Populations interact with other populations to form food chains and food networks. Each population serves a role in the ecosystem, such as decomposing dead organisms or preying on species and helping control its numbers.Learn more about Biology
There are many reasons that classifying organisms is important, such as helping understand the genetic relationships between different groups and species, helping with wide studies of organisms and helping to develop new biological sciences such as biogeography. Each of the groups and sets are created by studying the differences and similarities found in species and organisms known.Full Answer >
Carl Linnaeus grouped organisms by the binominal system, a system he invented for separating animals and plants into a genus name and a species name. Linnaeus is called "the Father of Taxonomy" for his work in species classification.Full Answer >
Viruses are named scientifically similarly to organisms; they are referred to by genus and species name. Above these, two classification systems, supplemental to each, create a taxonomy for viruses.Full Answer >
The four steps or conditions necessary for natural selection to occur are that more organisms are born than can survive, characteristics vary within a species, variations are inherited, and differences in reproduction and survival are due to variations. All four of these conditions must occur for natural selection to happen.Full Answer >
