10 biomes

  1. 1. The 10 Major BiomesBy: Ale Young and ----- ---------
  2. 2. Tropical Rainforest: Dominant WildlifeMany of the animals in the rainforest are adapted tolive in trees and may be brightly colored like manybutterflies and birds. Many also have loud vocalizationslike the jaguar or parakeet.Examples of Wildlife in the Rainforest are: sloths,anteaters, toucans, piranhas, anacondas, monkeys, andparrots.
  3. 3. Tropical Rainforest: Dominant Plants• Broad-leaved evergreen trees; ferns; large woody vines and climbing; orchids and bromeliads.• The curved leaves of forest trees have adapted to allow water to run off quickly to avoid growth of fungus and bacteria in the warm, wet tropical rainforest.
  4. 4. Tropical Rainforest: Abiotic Factors and Geographical Distribution• Abiotic factors: hot and wet year round; has a annual rainfall of more than 250 centimeters and has average humidity between 77 and 88%.• Tropical Rainforests are found in parts of South and Central America, Southeast Asia, parts of Africa, southern India, and northeastern Australia.
  5. 5. Tropical Dry Forests
  6. 6. Tropical Dry Forests: Dominant wildlifeTropical Dry Forests usually inhabit animals such as tigers, elephants, Indian rhinoceros,monkeys, termites and reptiles such as snakes and monitor lizardsAs a response to the environment, some of the reptiles burrow into the ground andpreform hibernation during drought seasons.
  7. 7. Tropical Dry Forests: Plants• Some plants that are adapted to live in tropical dry forests are trees that form a dense canopy during the wet season; drought- tolerant orchids; aloes and different types of palms.• A helpful adaptation that many plants have is an extra, waxy coating over the leaves to slow water evaporation during drought season.
  8. 8. Tropical Dry Forest: Geographic Distribution and Abiotic Factors.• Abiotic Factors- generally warm year-round; alternating wet and dry seasons; rich soil subject to erosion. Occasional risk of drought for plants.• Geographic Distribution- parts of Africa, South and Central America, Mexico, India, Australia and tropical islands.
  9. 9. Tropical Savanna
  10. 10. Tropical Savanna: AnimalsSome of the predators in the tropical savanna are lions, cheetahs, hyenas, andjackals.Examples of herbivores are elephants, giraffes, antelopes, and zebras.Other creatures that live in the tropical savanna are baboons, eagles,ostriches, weaver birds, and termites.
  11. 11. Tropical Savanna: Plants• Most of the plant life consists of tall grasses; sometimes drought-tolerant and fire resistant trees or shrubs. Thick roots helps absorb more water in areas of the savanna where the ground is dry.
  12. 12. Tropical Savanna: Abiotic factors & Geographic distribution• Abiotic Factors: warm temperatures; seasonal rainfall; compact soil; frequent fires set by lightning.• Geographic distribution: large parts of eastern Africa, southern Brazil, northern Australia.
  13. 13. Desert
  14. 14. Desert: Dominant Wildlife• Main Predators- Mountain Lions, gray foxes, and bobcats• Herbivores- mule deer, desert bighorn sheep, and kangaroo rats.• Other wildlife- bats, owls hawks, roadrunners, ants, beetles, wasps, rattlesnakes.• Major adaptations animals have for the desert include storing water and releasing very little, tolerate hypothermia, and dissipate heat.
  15. 15. Desert: Plants• Some of the most common desert plants are cacti, creosote bush and other plants with short growth cycles.• Plant leave behind seeds when they die as an adaptation to keep their species from dying out.
  16. 16. Desert: Abiotic Factors & Geographic Distribution.• Abiotic factors: Low precipitation; variable temperatures; soils rich in minerals but poor in organic materials.• Geographic distribution: Africa, Asia, the Middle East, United States, Mexico, South America, and Australia.
  17. 17. Temperate Grassland
  18. 18. Temperate Grassland: Dominant Wildlife• Predators- coyotes, badgers, wolves, and grizzly bears.• Herbivores- mule deer, pronghorn antelopes, rabbits, prairie dogs, and humanly introduced cattle.• Other wildlife- hawks, owls, bobwhites, prairie chickens, mountain plovers; snakes, ants and grasshoppers.• Numerous excavating animal species, when removing the ground, modify the mineral content of the soil and help vegetation in that area grow.
  19. 19. Temperate Grassland: Plants• Plants include lush grasses, herbs, and mostly drought, fire, and cold resistant plants.• We live in an area of temperate grassland.
  20. 20. Abiotic Factors and Geographic Distribution• Abiotic factors: warm to hot summers; cold winters; moderate, seasonal precipitation; fertile soils; occasional fires.• Geographic Distribution: central Asia, North America, Australia, central Europe, and upland plateaus in Africa.
