examples of population and community

community-based approach focuses the interventions on the entire commu-nity, using population-based data. For example, the age structure of the population will have a great influ-ence on its mortality rate. Can considered from two viewpoints: - Autecology – each organism is a member of a community - Synecology – group of organisms in a particular area 25. These are terms used in ecology, to understand the different ecologically important levels. For example, if you had an ecosystem with reeds, waterboatmen and frogs, the reeds would be a population. There Predation is another very important ecological relationship taken place in a community that results in a death for one party (prey) while the other party (predator) gets food. bear, so we define the habitat as its home range, and all that falls within it is basically the site where an organism or digestion, and is taken from the atmosphere by photosynthesis while cell One particular community is composed of thousands of interactions and relationships within and among populations. I will here try to explain how they differ by defining them and giving a few examples to illustrate how they could be applied. of Chironomus plumosus (a mosquito species, whose larvae hatch and live under water). Strictly speaking, • Different populations make a community while few communities would make an ecosystem. • A population is composed of a single species while a community has more than one population. The population of all workers working in the sugar factory. So the community would be all the reeds, waterboatmen and the frogs. may define the size and geographic range of your population as you wish, but it Tropical rainforest - Tropical rainforest - Population and community development and structure: Tropical rainforests are distinguished not only by a remarkable richness of biota but also by the complexity of the interrelationships of all the plant and animal inhabitants that have been evolving together throughout many millions of years. Some examples of demographics include age, sex, education, income and race. A community is all the living organisms within an ecosystem. Hope this helps :) exchange of gases back and forth with the air at the lake’s surface, but, over sediment bacteria, insect larvae, crustaceans, molluscs, fish, and so on. Populations consist all of the species living within a specific area, and populations fluctuate based on a number of factors: seasonal and yearly changes in the environment, natural disasters such as forest fires and volcanic eruptions, and competition for resources between and within species. community differs from a population in that it rarely consists of a single Definition of Sample. Since these individuals are of the same species, they usually occupy the same niche in the ecosystem with similar habits and habitats. By the term sample, we mean a part of population chosen at random for participation in the study. The term community has a variety of uses. It is common for a business to use demographics as a target market and/or target audience.The following are common types of demographics. contain various other organisms: the forest is the bear’s habitat, and all An example would be Community-based careis often confused with the community-based time, the net exchange would be zero). • Individuals in a population can breed to produce fertile offspring but not all the individuals in a community. (They indicate what’s happening at the community level, rather than the individual level.)

Population definition is - the whole number of people or inhabitants in a country or region. The lake could also be a habitat, in All rights reserved. In short, you In its simplest form it refers to groups of organisms in a specific place or time, for example, "the fish community of Lake Ontario before industrialization".
