Biome, the largest geographic biotic unit, a major community of plants and animals with similar life forms and environmental conditions. It includes various communities and is named for the dominant type of vegetation, such as grassland or coniferous for
The marine and freshwater biome types represent the most important examples of biomes since water is the main constituent of all living organisms. It is a major biomolecule of life. Additionally, a great number of living species live in marine and freshwater. Oceans have a great effect on the...
fauna and flora. The term is often limited to denote terrestrial habitats, e.g. tundra, coniferous forest, grassland. Oceans may be considered as a single biome (the marine biome), though sometimes this is subdivided, e.g. coral reef biome. There is no sharp distinction between adjacent bi...
Biodiversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth. A common measure of this variety, called species richness, is the count of species in an area. Biodiversity encompasses the genetic variety within
(4) In 2011, the Census of Marine Life estimated about 8.7 million eukaryote species on Earth. (5) Unfortunately, many of the living things (probably over five billion species) that ever lived on Earth became extinct. Watch this vid about the origin of life on Earth:...
Terrestrial ecosystem is a term for those ecosystems that are land-based. They are different from the second type of ecosystem, marine ecosystems.What is a Terrestrial Ecosystem? An ecosystem in biology is defined as a system that consists of biotic or living things that interact with each other...
“biome”, naming a “characteristic microbial community” in a “reasonably well-defined habitat which has distinct physio-chemical properties” as their “theatre of activity” (Table1). This definition represents a substantial advancement of the definition of a microbial community, as it defines ...
In terrestrial ecosystems, the role of photosynthesis is mainly filled by plants, while plankton (microscopic organisms) fills this role in marine ecosystems. This is an extremely important biotic factor, as many ecosystems are defined by what producers reside in them. For example, tropical ...
Carbon cycle is a process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.
What is the definition of a precipitation map? Precipitation Precipitation is basically water in a solid or liquid form that is produced when atmospheric water vapor condenses and falls. The common forms of precipitation are snow, rain, hail, and sleet. ...
