Terrestrial ecosystems occupy 55,660,000 mi 2 (144,150,000 km 2), or 28.26% of Earth's surface. [5] Major plant taxa in terrestrial ecosystems are members of the division Magnoliophyta (flowering plants), of which there are about 275,000 species, and the division Pinophyta (conifers), of which there are about 500 species.
Terrestrial gamma-ray flash, a burst of gamma rays produced in Earth's atmosphere; Terrestrial locomotion, evolutionary adaptation from aquatic types of locomotion; Terrestrial plant, a plant that grows on land rather than in water or on rocks or trees; Terrestrial planet, a planet that is primarily composed of silicate rocks, and thus "Earth-like"
The goat is a terrestrial animal.. Terrestrial animals are animals that live predominantly or entirely on land (e.g. cats, chickens, ants, most spiders), as compared with aquatic animals, which live predominantly or entirely in the water (e.g. fish, lobsters, octopuses), and semiaquatic animals, which rely on both aquatic and terrestrial habitats (e.g. platypus, most amphibians).
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 ...
[60] [61] The largest extant terrestrial animal is the African bush elephant (Loxodonta africana), weighing up to 12.25 tonnes [60] and measuring up to 10.67 metres (35.0 ft) long. [60] The largest terrestrial animals that ever lived were titanosaur sauropod dinosaurs such as Argentinosaurus , which may have weighed as much as 73 tonnes, and ...
One way of mapping terrestrial (land) biomes around the world. A biome (/ ˈ b aɪ. oʊ m /) is a distinct geographical region with specific climate, vegetation, and animal life. It consists of a biological community that has formed in response to its physical environment and regional climate. [1] [2] Biomes may span more than one continent.
A biogeographic realm is the broadest biogeographic division of Earth's land surface, based on distributional patterns of terrestrial organisms. They are subdivided into bioregions, which are further subdivided into ecoregions. A biogeographic realm is also known as "ecozone", although that term may also refer to ecoregions.
Terrestrial ecoregion, land ecoregions, as distinct from freshwater and marine ecoregions. Terrestrial ecosystem, an ecosystem found only on landforms. Terrestrial locomotion, movement among animals adapted from aquatic to terrestrial environments. Terrestrial planet, a planet that is composed primarily of silicate rocks or metals.
