Biomes

By Jackie Kaplan

tropical rain forest
Tropical Rain Forest
  • Average rainfall of 50 to 260 inches yearly
    • Often more than 100 inches
  • Temperatures generally range from 68*F to 93*F
  • 4 layers of strata
  • Mostly found near the equator
  • Mostly trees, but a variety of vine species and shrubs
  • Insects, mammals, birds, amphibians and reptiles, but insects are the most abundant
savanna
Savanna
  • Winter- About 4 inches of rainfall

Summer- Average rainfall of 15 to 25 inches of rainfall

  • Warm temperature year round, that rarely drops below 70 even in the winter
  • Rolling grasslands
  • Found on either side of the equator at the edge of tropical rainforests
  • Animal and plant life depends on the location of the savannas
  • Shrubs and isolated trees
  • Generally large herds of mammals live on savannas
deserts
Deserts
  • Hot deserts- About 15 cm yearly

Cold deserts- About 15-26 cm yearly

  • Temperature of Hot and dry deserts range from 68*F to 77*F
  • The maximum temperature of Hot deserts ranges from 110*F to 120*F
  • Cold deserts range from 28*F to 39*F in winter and from 70*F to 79*F in summer
  • Deserts are usually large areas of land with sand and little plant and animal life due to extreme temperature conditions
  • Hot and dry deserts are found mostly near the Tropic of Cancer and Tropic of Capricorn, and cold deserts are found mostly in artic areas
  • Vegetation is rare in hot and dry deserts, and in cold deserts about 10% is plants mostly deciduous or contain less spiny leaves
  • In hot and dry, and cold deserts only animals that are burrowers can survive to escape from extreme temperature conditions
  • Also in hot and dry deserts there are small nocturnal carnivores, insects, arachnids, birds and reptiles
chaparral
Chaparral
  • Very hot and dry, meaning little to no rainfall
  • Drought and fires happen quite often
  • Winter- Around 50*F

Summer- Around 104*F

  • A variety of terrain such as rocky hills, flat plains, and mountain slopes
  • The chaparral is found on each continent in little areas
  • Plants with adaptations of small, hard leaves that hold moisture
  • Animals that have adapted to the hot weather of the chaparral, mainly grassland and desert species
temperate grassland
Temperate Grassland
  • Little rainfall typically between 10 to 20 inches yearly, a lot of droughts and fires occur, but enough rainfall for grasses and some small trees to survive
  • Temperature depends on location
  • Rich mix of grasses and forbs and underlain by the world’s most fertile soil
  • Found in middle latitude, towards the middle of continents
  • Hundreds of species of plants live in the grasslands
  • Also many types of animals live in the grasslands depending on which type
temperate deciduous forest
Temperate Deciduous Forest
  • Average yearly temp is 50*F
  • There are 4 distinct seasons
  • Average rainfall of 30 to 60 inches yearly
  • Very fertile soil
  • Locate mostly in the northern hemisphere
  • A large variety of trees, flowers shrubs, mosses, etc.
  • Animals are generally either nut and acorn feeders, or omnivores
taiga coniferous forest
Taiga (Coniferous Forest)
  • Winter- Temperatures range from

-65*F to 30*F

Summer- 20*F to 70*F

  • Annual precipitation is about 12-33 inches yearly
  • Forest with many trees and mountains
  • Located in North America and Eurasia, overlying areas that were formerly glaciers
  • Not a lot of species of plants in the taiga due to extreme conditions, most plants are coniferous trees
  • Animals of the taiga tend to be predators
tundra
Tundra
  • Vast treeless land that covers 20% of earth’s surface
  • -18*F annually
  • Earth’s coldest and driest biome
  • 6-10 inches of precipitation yearly, mostly snow
  • Located in the northern hemisphere, encircling the north pole and extending south to the coniferous forests of the taiga
  • Barely any plants, the common plants are shrubs, sedges, lichens, and grasses
  • There are a lot of animals in the tundra, not many species but they are abundant
  • They are animals that feed on the lichens and plants of the tundra
