An ecosystem comprises the geography, temperatures, rainfall, plants and animals in a specific area. These features include the physical, biological and chemical aspects of a specific habitat. Each of the types of ecosystems have various abiotic features, such as sunlight, soil moisture, rainfall and temperatures. Biotic features of an ecosystem include interrelationships among predators, prey and detrivores--organisms that help to break down decaying or dead organic matter. Polar ecosystems are located on the top and bottom of Earth. These ecosystems often have flat surfaces covered by ice for much of the year. The precipitation is typically snow, although it is possible to see hail or sleet on warmer days. The animals in polar ecosystems are specially adapted to extreme cold. Polar animals include penguins, polar bears, seals and arctic birds. Mountain Zones Mountain ecosystems exist at high altitudes and frequently have limited vegetation, although bushy plants may be evident. The landscape is rocky, but they have some of the most beautiful ecosystem images on Earth. Temperatures tend to be low due to the height of the mountains. Precipitation tends to be in the form of snow in the higher regions, but mist and rain are possible as well. The tundra ecosystem is similar to the polar ecosystem. Often polar regions are referred to as tundra zones. Tundra zones are characterized by permafrost, or frozen ground, and limited vegetation. Long periods of light and darkness alter...

Animals Living in Polar Regions Climatic conditions in the polar region are always on the extreme side. There is extreme cold and most of the areas are covered with snow. The sunrise and sunset persist for 6 months. The winters are so cold that the 0c. The animals living in these conditions include the polar bear as well as penguin. So how do they adapt to these conditions? Adaptations of Polar Bear • Their white fur gets camouflaged against the white background of snow protecting it from predators and also helps them catch their prey. • Two thick layers of fur act as an insulator protecting them from the surrounding harsh climate. • The polar bear carries out physical activities like swimming in order to keep warm • In order to avoid getting overheated they move slowly and rest often. • A strong sense of smell helps them in catching a prey • Can remain submerged underwater closing its nostrils Adaptations of Penguins • Its white colour helps it blend in with the white background • Thick skin and a lot of fat protect it from cold • They huddle together in groups to keep themselves warm • They have webbed feet and they streamline their body while swimming which makes them good swimmers Other Animals Living in Polar Regions The other animals living in polar regions include a variety of fishes, reindeers, seals, whales, foxes and birds. While fish are able to remain underwater for long periods of time and survive the cold weather, the birds cannot do that. They migrate to war...

taiga, also called boreal forest, The taiga, which is also known as the boreal (meaning northern) Pinus), Picea), Larix), Abies)—and to a lesser degree by some deciduous genera such as Betula) and Populus). These trees reach the highest latitudes of any trees on Origin During the final period of maximum cold glaciers began to retreat gradually about 18,000 years ago, species of the taiga began to move northward in Europe and North America. In eastern and central North America the northward movement of the forest was relatively steady and gradual. An exception to this progression occurred about 9,000 years ago in western Because so much of Earth’s water was bound up in ice at this time, sea levels were lower than they are today, and this allowed migrations of various terrestrial species to occur. Many areas that are now islands were then connected to the nearby mainland; e.g., the Distribution The taiga regions of Pinus sylvestris). The position of the taiga generally is controlled by the degree of warmth experienced during the forest-tundra. The closed-canopy forest is the southernmost portion of the taiga. It contains the greatest richness of species, the warmest soils, the highest productivity, and the longest growing season within the boreal zone. North of the closed-canopy forest is the Get a Britannica Premium subscription and gain access to exclusive content.

The tropical regions of the world encompass the areas from the Tropic of Cancer (latitude 23 degrees 26 minutes North) in the Northern Hemisphere to the Tropic of Capricorn (latitude 23 degrees 26 minutes South) in the Southern Hemisphere. Bisected by the equator, these regions contain tremendous diversity in plant and animal species. Approximately 50 percent of known plant species are thought to originate in the tropics, giving it the highest plant diversity of any zone in the world. Over 14,000 known plant species reside within the Amazon region alone. Many familiar everyday products such as coffee and vanilla derive from tropical plants, and one mention of gaudy macaws and screeching monkeys can bring to mind the tropics. But they represent only a portion of the spectacular range of species in those regions. TL;DR (Too Long; Didn't Read) The tropical regions of the world house a tremendous amount of diverse plants and animals. While the tropics teem with vibrant animals such as parrots and monkeys, and popular food plants such as coffee and vanilla, many other species abound, and others have yet to be discovered. Tropical Plant Food Resources From everyday foods such as chocolate and sugar to exotic spices, fruits and vegetables, plants from tropical regions enhance people’s diets. Beverages such as coffee, cocoa (derived from cacao), tea and kava derive from tropical plants. Coffee alone is considered one of the most valuable tropical exports in the world. Vanilla is d...

Polar region • Polar bears and penguins live in the polar region • Because of surrounding frigid air masses, the climates at the north and south poles are polar. • The hottest months in this climatic zone average less than 10 degrees Celsius. • This is lower than the average temperature in tropical zones during the coldest months. • Their adaptations include a white look that serves as concealment against predators on snow and ice. Tropical rainforests • Tropical rainforests are home to a vast assortment of flora and animals due to the frequent warmth and rain. • Among the most frequent organisms found in rainforests are monkeys, apes, red-eyed frogs, gorillas, tigers, elephants, leopards, lizards, snakes, birds, and insects. • The tropical wet evergreen forest may be found in areas where has been more than 200 cm of rain and temperatures range from 15 to 30 degrees Celsius. • They make up around 7% of the earth's surface. • They're mainly located around the equator.

What Animals Live In The Tropical Rainforest? Tropical rainforests range between the Tropic of Cancer and the Tropic of Capricorn (in places with high annual precipitation), and extend for much of the Earth's circumference. These areas are rich in biodiversity, with as much as half of all known species of flora and fauna residing under their dense canopy. Of that impressive census, there are some iconic animals that instantly spring to mind. Here are eleven such specimens that reside in the tropical rainforests of the world.

The stand-out spots are similar to the leopards of Africa and Asia, but a small dot in the center is the key point of differentiation. The jaguar is the biggest cat in the Americas and the third biggest in the world (behind lions and tigers). These magnificent carnivores are solitary but highly-effective night hunters, both on land and in the water. They have even been known to attack caimans. Jaguars are classified as Near Threatened on the International Union for Conservation of Nature's Red List. Since the 1880s, they have lost nearly half of their territory and continue to face threats from poachers and retaliatory killings by cattle ranchers. Jaguars rely on the Amazon Basin and some parts of Central America, for their survival. Read More Gorillas A gorilla female and i...
