what is a ecosystem
a biological community of interacting organisms and their physical environment.
consumer
a person who purchases goods and services for personal use
food chain
a hierarchical series of organisms each dependent on the next as a source of food
topographic factors
Topographic factors such as elevation, slope angle, slope aspect, general curvature, plan curvature, and profile curvature are considered as the main causes of landslides. In order to determine the dominant topographic factors in landslide mapping analysis, a study was conducted and presented in this paper.
species evenness
Species evenness is a description of the distribution of abundance across the species in a community. Species evenness is highest when all species in a sample have the same abundance. Evenness approaches zero as relative abundances vary.
what is a biotic
relating to or resulting from living things, especially in their ecological relations.
autotroph
an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide
food web
biodiversity
the variety of life in the world or in a particular habitat or ecosystem.
5 things driving extinction
what is a abiotic
heterotroph
an organism deriving its nutritional requirements from complex organic substances
energy pyramid
Description. An energy pyramid, also known as a trophic or ecological pyramid, is a graphical representation of the energy found within the trophic levels of an ecosystem. The bottom and largest level of the pyramid is the producers and contains the largest amount of energy.
species biodiversity
the variety of living species
carnivore
an animal that feeds on flesh
what is a producer
a person, company, or country that makes, grows, or supplies goods or commodities for sale
scavenger
an animal that feeds on carrion, dead plant material, or refuse
climatic factors
Climatic factors are the temperature of the region/climatic warming, duration of ablation season, proportion of winter and summer precipitation, etc. From: Understanding Present and Past Arctic Environments.
genetic diversity
Genetic diversity is the biological variation that occurs within species. It makes it possible for species to adapt when the environment changes. Genetic diversity is particularly important under rapid environmental change, such as in the Baltic Sea.
herbivore
an animal that feeds on plants.
what is a decomposer
an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
trophic level
edaphic factors
The edaphic factor includes the physical, chemical, and biological properties of soil that result from biologic and geologic phenomena or anthropogenic activities. Discontinuities in the edaphic factor contribute to the intriguing patterns of diversity we see in the biotic world.
species richness
Species richness is simply the number of species in a community. Species diversity is more complex, and includes a measure of the number of species in a community, and a measure of the abundance of each species. Species diversity is usually described by an index, such as Shannon's Index H'.
