Tropical rain forest l.jpg
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 l.jpg

  • 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 l.jpg

  • 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 l.jpg

  • 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 l.jpg
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 l.jpg
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 l.jpg
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 l.jpg

  • 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
