The process of separating organisms by their similarities and differences is known as classification or taxonomy. Organisms are grouped based on shared characteristics to determine their relationships and evolutionary history. This helps scientists better understand biodiversity and create a system for organizing and naming different species.
That group of organisms of a certain species in one area at a given time is known as a population. A population consists of individuals of the same species that can interbreed and share a common gene pool.
This is called genetic divergence. Over time, accumulated genetic differences between populations can lead to the formation of new species through a process known as speciation. This can occur through various mechanisms such as natural selection, genetic drift, and isolation.
Those are invasive species.
The organisms of all species in a given area are collectively known as a community. They interact with each other and their environment within the same habitat.
Naming and classifying of organisms is known as taxonomy. It involves organizing organisms into hierarchical categories based on their similarities and differences. The system used for naming organisms is called binomial nomenclature, where each organism is given a unique two-part scientific name consisting of its genus and species.
Species
Competition: intraspecifically (between members of the same species) or interspecifically (between members of different species).
There are approximately 120 known species of archaebacteria in the world. These organisms are known for their ability to thrive in extreme environments.

They are called bellwether species, also known as sentinel species.
Organisms are classified based on their evolutionary relationships and shared characteristics. This classification system, known as taxonomy, groups organisms into hierarchical categories such as kingdom, phylum, class, order, family, genus, and species. The goal is to reflect the evolutionary history and genetic relatedness among different organisms.
That group of organisms of a certain species in one area at a given time is known as a population. A population consists of individuals of the same species that can interbreed and share a common gene pool.
These organisms are known as pioneer species because they are the first species present; pioneer species must be hardy and strong, just like human pioneers.
Every known organism is classified and named under the system of taxonomy, which organizes living organisms into hierarchical groups based on their characteristics and evolutionary relationships. The scientific names given to organisms consist of a genus and species name, known as binomial nomenclature, to provide a universal and precise way to identify and differentiate between species.
Parasites
A species is a group of closely related organisms. Organisms belong to the same species if they can mate and produce fertile offspring. A lion and tiger are not the same species because they can make a liger, but it will not be fertile.
