What is the difference between an individual and an ecosystem?
A community is the set of all living organisms that develop their life cycles in a certain area or territory. That is to say, in the same ecological environment, delimited by mainly physical characteristics; for example, a lake, a forest, a savannah, etc. Logically, each population is made up of an independent organism, which fulfills its vital functions on its own, but which in turn depends on all the other inert factors (water, soil, salts, temperature, pressure, etc.).
All the living beings in this environment are called biological or biotic factors; and the inert factors of this environment with which the living beings that live there are related are called abiotic.
Ecosystem is the set formed by the biological components (biotic factors) of the community and the inert factors (without life or abiotic factors) that influence these living beings and that condition their way of life, their adaptations and their mutual relations. For example, a lagoon where frogs, mosquitoes, shrimp, fish, which depend on water, oxygen, temperature, etc., coexist.
What is a community in an ecosystem
In ecology, a community is a group or association of populations of two or more different species occupying the same geographic area at the same time, also known as a biocenosis. The term community has a variety of uses. In its simplest form it refers to groups of organisms in a specific place or time, e.g., “the fish community of Lake Ontario before industrialization.”
Community ecology has its origins in European plant sociology. Modern community ecology examines patterns such as variation in species richness, equity, productivity, and food web structure (see community structure); it also examines processes such as predator-prey population dynamics or succession.
Niche partitioning reduces competition between species. Such that species can coexist as they suppress their own growth more than they limit the growth of other species. Competition within a species is greater than competition between species. Intraspecific competition is greater than interspecific competition.
Individual, population, community, ecosystem examples
In the nutrient cycling diagrams, everything seems to work in an ideal and stable way, and nutrients move through the ecosystem “smoothly”. Unfortunately, human activity has hindered some of the processes that have induced major alterations in their trajectories.
For example, the extensive use of phosphorus fertilizers on crops has led to an enormous increase in the extraction of phosphate rocks for processing. Fertilizers are applied to farmland in excessive quantities and their reincorporation into the soil has been neglected, which means that they are “carried” by water currents and eventually end up in the sea. There they accumulate on the bottom and only a little is incorporated by the algae in suspension in the water and are eventually transferred to the fish, which, in turn, when eaten by some seabirds, can be deposited as guano on the islets. But in reality, they are not reincorporated into the ecosystem and do not circulate. This makes phosphorus sources increasingly scarce for terrestrial ecosystems and agriculture, and in the future we are expected to have a shortage of phosphorus.
What is an ecosystem?
An ecosystem is a system that consists of a set of living organisms and the physical environment.
