A community differs from a population in that it rarely consists of a single species, but most often includes all various sorts of organisms, simply because it contains all living creatures in the area, including microbes, fungi, animals and plants. A species comprises the biggest possible gene pool. Under favorable environmental conditions and plentiful resources, the number of individuals in a population increases rapidly. There are several types of. Species and population are two basic levels of classification of organisms in ecology. Define species, population and community. A species refers to individual organisms that can reproduce and produce fertile offspring. Briefly explain how each attribute shapes population dynamics. Population: Two populations of the same species can interbreed with each other. The carrying capacity of the environment is the number of individuals that the resources can support. +5. Species consist of a similar type of individuals who are capable of interbreeding with each other. Speciation occurs when the variations are intolerable enough to make two incompatible groups of individuals who cannot interbreed with each other. Species A species is a group of organisms that can breed together to produce fertile offspring populations are all the organisms of one species in a habitat at a given time Define abiotic and ecosystem. They are sometimes called levels of organization in ecology. The other higher levels of classification include community and ecosystem. Based on the feeding behavior, a particular population may continue three types of symbiotic interactions with other populations or with the environment. If the number of individuals in a species is increased up to the carrying capacity of the environment, a population of that particular species is called as a K-selected species. N.p., n.d. Population: A population is a group of organisms who belong to a particular species, living and interbreeding at the same place at a certain time. Populations are categorized based on the growth characteristics of the species in a particular habitat as K-selected species and r-selected species.
