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.Know More
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

Biologists have developed a specific system for classifying all living organisms which is based on dividing all known organisms into groups according to common features which scientists believe are biologically significant. This system, known as the Classification of Living Things, gradually isolates each living organism into the following groups: Kingdom, Phylum, Class, Order, Family, Genus, and Species.Full Answer >
Vacuoles vary in function between organisms and even within the same cell, but the most frequent use is the storage of water or nutrients. A vacuole is really a general-purpose, empty membrane organelle that is filled with whatever the cell needs to keep separate from the rest of the cytoplasm. As such, different vacuoles also store waste or even toxins, and some organisms have other uses for them.Full Answer >
