Ecological units refer to specific levels or degrees of organization within ecological systems. The units that are most commonly used and discussed within ecological systems are those at the levels of individuals, populations , communities , and ecosystems . [ 1 ]
The higher levels of this scheme are often referred to as an ecological organisation concept, or as the field, hierarchical ecology. Each level in the hierarchy represents an increase in organisational complexity , with each "object" being primarily composed of the previous level's basic unit. [ 2 ]
If a country does not have enough ecological resources within its own territory to cover its population's footprint, then it runs an ecological deficit and the country is termed an ecological debtor. Otherwise, it has an ecological reserve and it is called a creditor. [1] To a significant degree, biocapacity correlates with access to water ...
A pyramid of biomass shows the relationship between biomass and trophic level by quantifying the biomass present at each trophic level of an ecological community at a particular time. It is a graphical representation of biomass (total amount of living or organic matter in an ecosystem) present in unit area in different trophic levels.
Ecosystem classifications are specific kinds of ecological classifications that consider all four elements of the definition of ecosystems: a biotic component, an abiotic complex, the interactions between and within them, and the physical space they occupy. Biotic factors of the ecosystem are living things; such as plants, animals, and bacteria ...
The planned ecological succession in the rainforest and strategies to protect the area from harsh incident sunlight and salt aerosols from the ocean worked well, and a surprising amount of the original biodiversity persisted. [29] Biosphere 2 in its early ecological development was likened to an island ecology. [30]
Ecosystem ecology is philosophically and historically rooted in terrestrial ecology. The ecosystem concept has evolved rapidly during the last 100 years with important ideas developed by Frederic Clements, a botanist who argued for specific definitions of ecosystems and that physiological processes were responsible for their development and persistence. [2]
Ecological classification or ecological typology is the classification of land or water into geographical units that represent variation in one or more ecological features. . Traditional approaches focus on geology, topography, biogeography, soils, vegetation, climate conditions, living species, habitats, water resources, and sometimes also anthropic factors.
