The marine biome Online exhibits : The world's biomes The marine biome Marine regions cover about three-fourths of the Earth's surface and include oceans, coral reefs, and estuaries. Marine algae supply much of the world's oxygen supply and take in a huge amount of atmospheric carbon dioxide. The evaporation of the seawater provides rainwater for the land. Oceans The largest of all the ecosystems, oceans are very large bodies of water that dominate the Earth's surface. The intertidal zone is where the ocean meets the land — sometimes it is submerged and at other times exposed, as waves and tides come in and out. The pelagic zone includes those waters further from the land, basically the open ocean. The benthic zone is the area below the pelagic zone, but does not include the very deepest parts of the ocean (see abyssal zone below). The deep ocean is the abyssal zone. Coral reefs Coral reefs are widely distributed in warm shallow waters.
rainforest picture The desert biome Online exhibits : The world's biomes The desert biome Deserts cover about one fifth of the Earth's surface and occur where rainfall is less than 50 cm/year. Although most deserts, such as the Sahara of North Africa and the deserts of the southwestern U.S., Mexico, and Australia, occur at low latitudes, another kind of desert, cold deserts, occur in the basin and range area of Utah and Nevada and in parts of western Asia. Most deserts have a considerable amount of specialized vegetation, as well as specialized vertebrate and invertebrate animals. Soils often have abundant nutrients because they need only water to become very productive and have little or no organic matter. There are relatively few large mammals in deserts because most are not capable of storing sufficient water and withstanding the heat. Desert biomes can be classified according to several characteristics. The seasons are generally warm throughout the year and very hot in the summer. Canopy in most deserts is very rare.

Australian Desert Plants Australian desert plants are clever survivors. Australia is the world’s driest inhabited continent with 70% of its landmass being deserts or semi-deserts. It is a harsh country for plants to live – it is extremely dry and it gets periods of drought that can last for years. It is extremely hot, with temperatures in 50s (°C) during the summer so if it does rain, evaporation is quick. The soils are ancient, rich in salt and extremely infertile. How can plants handle all this, and what plants are found in Australian deserts? Ausralian desert landscape, by AllPosters. Trees and Shrubs Some of the trees found in Australian deserts are the beautiful Ghost Gum (Corymbia sp.) which is almost iconic with its smooth silvery white bark; Mulga (Acacia aneura), Sandalwood (Santalum spicatum); Northern Cypress Pine (Callitris glaucophylla); Sandhill Wattle (Acacia ligulata); and Western Myall (Acacia papyrocarpa).

Tropical Rainforest Plants in Australia There are many different kinds of tropical rainforest plants in Australia. Tropical rainforests are some of the species-richest ecosystems in the world. They grow in areas with the best conditions for plant growth in the world – with year-around warm temperatures, plenty of sunlight and rainfall. Poster by AllPosters. Despite the fact that their soils are poor on nutrients, they support so many species that they have been compared to coral reef ecosystems. Tropical Rainforest Plants: Tall Trees The most successful plants in the tropical rainforests are the tall trees. Tropical Rainforest Plants: Buttresses and Fig Trees These tall trees often have buttress roots, because the rainforest ground is often very moist, and just like mangroves, rainforest trees need to keep parts of their roots above the ground to get oxygen. Tropical Rainforest Plants: Different Types of Ferns Another group of common tropical rainforests plants are ferns.
Australian Animals | Facts | List | Native | Endangered | Introduced Why are Australian Animals Different? Unique and Strange Animals in Australia The reason Australia has such unique and unusual animals (and plants) is that it was isolated from the rest of the world for over 60 million years. Separated by vast oceans, Australian plants and animals evolved independently of those in other parts of the world. Interestingly many Australian fauna fill similar niches in the local environment to animals elsewhere in the world.
