What are the types characteristics features functions and structures of a desert ecosystem grassland ecosystem and aquatic ecosystem?

Answer 1

desert eco-system Flora of Baja California Desert, Cataviña region, Mexico.A large, dry, barren region, usually having sandy or rocky soil and little or no vegetation. Water lost to evaporation and transpiration in a desert exceeds the amount of precipitation; most deserts average less than 25 cm (9.75 inches) of precipitation each year, concentrated in short local bursts. Deserts cover about one fifth of the Earth's surface, with the principal warm deserts located mainly along the Tropic of Cancer and the Tropic of Capricorn, where warm, rising equatorial air masses that have already lost most of their moisture descend over the subtropical regions. Cool deserts are located at higher elevations in the temperate regions, often on the lee side of a barrier mountain range where the prevailing winds drop their moisture before crossing the range.A Closer Look A desert is defined not by temperature but by the sparse amount of water found in a region. An area with an annual rainfall of fewer than 25 centimeters (9.75 inches) generally qualifies as a desert. In spite of the dryness, however, some animals and plants have adapted to desert life and thrive in these harsh environments. While different animals live in different types of deserts, the dominant animals of warm deserts are reptiles, including snakes and lizards, small mammals, such as ground squirrels and mice, and arthropods, such as scorpions and beetles. These animals are usually nocturnal, spending the day resting in the shade of plants or burrowed in the ground, and emerging in the evenings to hunt or eat. Warm-desert plants are mainly ground-hugging shrubs, small wooded trees, and cacti. Plant and animal life is scarcer in the cool desert, where the precipitation falls mainly as snow. Plants are generally scattered mosses and grasses that are able to survive the cold by remaining low to the ground, avoiding the wind, and animal life can include both large and small mammals, such as deer and jackrabbits, as well as a variety of raptors and other birds.aquatic ecosystem aquatic ecosystem is an ecosystem located in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. Marine ecosystems cover approximately 71% of the Earth's surface and contain approximately 97% of the planet's water. They generate 32% of the world's net primary production. They are distinguished from freshwater ecosystems by the presence of dissolved compounds, especially salts, in the water. Approximately 85% of the dissolved materials in seawater are sodium and chlorine. Seawater has an average salinity of 35 parts per thousand (ppt) of water. Actual salinity varies among different marine ecosystems. Marine ecosystems can be divided into the following zones: oceanic (the relatively shallow part of the ocean that lies over the continental shelf); profundal (bottom or deep water); benthic (bottom substrates); intertidalgrassland ecosystemA biological community that contains few trees or shrubs, is characterized by mixed herbaceous (nonwoody) vegetation cover, and is dominated by grasses or grasslike plants. Mixtures of trees and grasslands occur as savannas at transition zones with forests or where rainfall is marginal for trees. About 1.2 × 108 mi2 (4.6 × 107 km2) of the Earth's surface is covered with grasslands, which make up about 32% of the plant cover of the world. In North America, grasslands include the Great Plains, which extend from southern Texas into Canada. The European meadows cross the subcontinent, and the Eurasian steppe ranges from Hungary eastward through Russia to Mongolia; the pampas cover much of the interior of Argentina and Uruguay. Vast and varied savannas and velds can be found in central and southern Africa and throughout much of AustraliaGrasslands occur in regions that are too dry for forests but that have sufficient soil water to support a closed herbaceous plant canopy that is lacking in deserts. Thus, temperate grasslands usually develop in areas with 10-40 in. (25-100 cm) of annual precipitation, although tropical grasslands may receive up to 60 in. (150 cm). Grasslands are found primarily on plains or rolling topography in the interiors of great land masses, and from sea level to elevations of nearly 16,400 ft (5000 m) in the Andes. Because of their continental location they experience large differences in seasonal climate and wide ranges in diurnal conditions. In general, there is at least one dry season during the year, and drought conditions occur periodically

Answer 2

Desert ecosystem: Characterized by low rainfall, extreme temperature variations, and sparse vegetation adapted to drought conditions. Common features include cacti, succulents, and hardy animal species like snakes and lizards. Functions include soil stabilization, water conservation, and unique plant adaptations such as deep root systems or water storage tissues.

Grassland ecosystem: Characterized by vast open spaces with grasses as the dominant vegetation. Common features include grazers like bison or antelope and burrowing animals like prairie dogs. Functions include carbon sequestration, support for biodiversity, and habitat for native bird species.

Aquatic ecosystem: Characterized by the presence of water bodies such as oceans, lakes, rivers, and wetlands. Common features include aquatic plants, fish, invertebrates, and aquatic mammals like dolphins. Functions include nutrient cycling, oxygen production, and providing habitat for a diverse range of species. Structures can include coral reefs, kelp forests, and estuaries.

Answer 3

An ecosystem, a habitat,and a community alike by an habitat is made by an ecosystem.
