  2. Ecological classification - Wikipedia

    en.wikipedia.org/wiki/Ecological_classification

    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.

  3. Biogeography - Wikipedia

    en.wikipedia.org/wiki/Biogeography

    Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area. [1] Phytogeography is the branch of biogeography that studies the ...

  4. Geobiology - Wikipedia

    en.wikipedia.org/wiki/Geobiology

    A classic example of co-evolution is the evolution of oxygen-producing photosynthetic cyanobacteria which oxygenated Earth's Archean atmosphere. The ancestors of cyanobacteria began using water as an electron source to harness the energy of the sun and expelling oxygen before or during the early Paleoproterozoic .

  5. Natural environment - Wikipedia

    Wildlife includes all non-domesticated plants, animals and other organisms. Domesticating wild plant and animal species for human benefit has occurred many times all over the planet, and has a major impact on the environment, both positive and negative. Wildlife can be found in all ecosystems.

  6. Biome - Wikipedia

    Physiognomy: sometimes referring to the plants' appearance; or the biome's apparent characteristics, outward features, or appearance of ecological communities or species - including plants. Biome: a grouping of terrestrial ecosystems on a given continent that is similar in vegetation structure, physiognomy, features of the environment and ...

  7. Earth science - Wikipedia

    en.wikipedia.org/wiki/Earth_science

    Geology is broadly the study of Earth's structure, substance, and processes. Geology is largely the study of the lithosphere, or Earth's surface, including the crust and rocks. It includes the physical characteristics and processes that occur in the lithosphere as well as how they are affected by geothermal energy. It incorporates aspects of ...

  8. Tropical rainforest - Wikipedia

    en.wikipedia.org/wiki/Tropical_rainforest

    Rainforests are home to half of all the living animal and plant species on the planet. [7] Two-thirds of all flowering plants can be found in rainforests. [ 5 ] A single hectare of rainforest may contain 42,000 different species of insect, up to 807 trees of 313 species and 1,500 species of higher plants. [ 5 ]

  9. Lake ecosystem - Wikipedia

    en.wikipedia.org/wiki/Lake_ecosystem

    The vast majority of bacteria in lakes and ponds obtain their energy by decomposing vegetation and animal matter. In the pelagic zone, dead fish and the occasional allochthonous input of litterfall are examples of coarse particulate organic matter (CPOM>1 mm). Bacteria degrade these into fine particulate organic matter (FPOM<1 mm) and then ...
