  2. Ecosystem - Wikipedia

    en.wikipedia.org/wiki/Ecosystem

    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 ...

  3. Marginal distribution (biology) - Wikipedia

    en.wikipedia.org/wiki/Marginal_distribution...

    Abiotic and biotic factors may work together in determining the range of a species. An example might be some obligate seeder plants where the distribution is limited by the presence of wildfires, which are needed to allow their seed bank to germinate, and also use dispersal of their seeds mediated by ants.

  4. Montane ecosystems - Wikipedia

    en.wikipedia.org/wiki/Montane_ecosystems

    The biome, called "Montane grasslands and shrublands", often evolved as virtual islands, separated from other montane regions by warmer, lower elevation regions, and are frequently home to many distinctive and endemic plants which evolved in response to the cool, wet climate and abundant sunlight.

  5. Grassland - Wikipedia

    en.wikipedia.org/wiki/Grassland

    Grassland in all its form supports a vast variety of mammals, reptiles, birds, and insects. Typical large mammals include the blue wildebeest, American bison, giant anteater, and Przewalski's horse. [21] The plants and animals that live in grasslands are connected through an unlimited web of interactions.

  6. Temperate grasslands, savannas, and shrublands - Wikipedia

    en.wikipedia.org/wiki/Temperate_grasslands...

    Temperate grasslands, savannas, and shrublands are terrestrial biomes defined by the World Wide Fund for Nature. [1] The predominant vegetation in these biomes consists of grass and/or shrubs . The climate is temperate and ranges from semi-arid to semi-humid.

  7. Ecosystem diversity - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_diversity

    Ecosystem diversity addresses the combined characteristics of biotic properties which are living organisms (biodiversity) and abiotic properties such as nonliving things like water or soil (geodiversity). It is a variation in the ecosystems found in a region or the variation in ecosystems over the whole planet.

  8. Biocoenosis - Wikipedia

    en.wikipedia.org/wiki/Biocoenosis

    Biotic communities vary in size, and larger ones may contain smaller ones. Species interactions are evident in food or feeding relationships. A method of delineating biotic communities is to map the food network to identify which species feed upon which others and then determine the system boundary as the one that can be drawn through the ...

  9. Habitat - Wikipedia

    en.wikipedia.org/wiki/Habitat

    The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while ...
