Both describe the groups of individuals living in a particular ecosystem. • A population is composed of a single species while a community has more than one population. What is the Difference Between Population and Community – Comparison of Key Differences, Community, Ecosystem, Exponential Growth, Interspecific Interactions, Intra-Specific Interactions, Logistic Growth, Population, Population Density, Population Distribution, Population Dynamics. What is a Population – Definition, Features, Interactions 2. Population. The two observable types of population growths are exponential growth and logistic growth. Hence, this is the main difference between population and community. It would be easy to understand when it is introduced as a collection of populations living in a particular place at a given time. A population consists of all the genes of a particular species, which means the gene pool is represented in the entity of population. 4. There are no pray-predator relationships among individuals in a population while pray-predator relationships occur among individuals in a community. Another major difference between population and community is that a population consists of a single species while a community consists of several species living together. Intra-specific competition occurs when the individuals of the population have to compete with each other for the limited resources in the ecosystem. As above discussed an ecosystem is the diversity of many communities of organisms where they interact with living (biotic) as well as nonliving (abiotic) thing whereas community contains the variety of populations of different species linking with each other in a region. Figure 1: King Penguins at Salisbury Plain. • The number of individuals is higher in a community than in a population of the same ecosystem. Though the individuals that belong to the different species interbreed, a number of ecological relationships occur between them within the community called interspecific interactions. Instead of counting each individual in a population, scientists perform sampling techniques to estimate the population sizes. Here, the number of individuals per unit geographical area of a particular population is the population density. “Carabus auratus with prey” By Soebe – Own work (CC BY-SA 3.0) via Commons Wikimedia, Lakna, a graduate in Molecular Biology & Biochemistry, is a Molecular Biologist and has a broad and keen interest in the discovery of nature related things, What is the Difference Between Population and Community, What are the Similarities Between Population and Community. Since these individuals are of the same species, they usually occupy the same niche in the ecosystem with similar habits and habitats. Furthermore, a population consists of a single species while a community consists of several species living together. Therefore, the size of the population varies over time due to birth, death, immigration, and emigration. 1. The study of the changes in the size, structure, birth rate, growth rate, death rate, and migration rate of a population is known as the population dynamics. Populations are subjected to change with time according to the environmental changes. A group of populations make up a community in a particular ecosystem while a community … All the individuals of a population are morphologically and behaviourly similar. On the other hand, population distribution is the location of individuals within a specific area. One particular community is composed of thousands of interactions and relationships within and among populations. Because of the above, all the individuals in a population are morphologically and behaviorally similar while the individuals in a community can be categorized into groups in terms of morphology and behaviour.

There are difference characteristics about the two levels and the two should be understood separately in order to identify the difference between those. Moreover, it increases under favourable environmental conditions and plentiful resources. This process is known as biocoenosis, the interacting organisms living together in a particular habitat. Moreover, individuals in a population freely interbreed while interbreeding is absent among the different individuals of a community. Community. “How Animal Populations Interact and Change Over Time.” ThoughtCo, Available Here2. Population is a widely used term in many disciplines to refer a closely associated group of one kind. Compare the Difference Between Similar Terms. The success of a particular population could be determined via studying the change of population sizes over a timescale, which could be weeks, months, seasons, years, or decades. Population and community are two different levels of biotic assemblages in any ecosystem.
