Linnaeus presented early ideas found in modern aspects to human ecology, including the balance of nature while highlighting the importance of ecological functions (ecosystem services or natural capital in modern terms): "In exchange for performing its function satisfactorily, nature provided a species with the necessaries of life" [10]: 66 The ...
An example of this could be that of the marine ecosystem which can be an umbrella term for all organisms living in oceanic conditions. [7] However, a habitat in the Gulf of Maine varies widely that the one of the Great Barrier Reef , despite both of them falling under the marine ecosystem term.
For example, ecosystems can be quite different if situated in a small depression on the landscape, versus one present on an adjacent steep hillside. [ 9 ] : 39 [ 10 ] : 66 Other external factors that play an important role in ecosystem functioning include time and potential biota , the organisms that are present in a region and could ...
A bear with a salmon. Interspecific interactions such as predation are a key aspect of community ecology.. In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage.
The relationship between ecosystem complexity and stability is a major topic of interest in ecology.Use of ecological networks makes it possible to analyze the effects of the network properties described above on the stability of an ecosystem.
Ecosystem services are ecologically mediated functional processes essential to sustaining healthy human societies. [6] Water provision and filtration, production of biomass in forestry, agriculture, and fisheries, and removal of greenhouse gases such as carbon dioxide (CO 2) from the atmosphere are examples of ecosystem services essential to public health and economic opportunity.
Ecological literacy (also referred to as ecoliteracy) is the ability to understand the natural systems that make life on earth possible. To be ecoliterate means understanding the principles of organization of ecological communities (i.e. ecosystems) and using those principles for creating sustainable human communities.

[20] The parasite either feeds on the host, or, in the case of intestinal parasites, consumes some of its food.
