1. Biomes
By Jackie Kaplan

2. 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

3. 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

4. Deserts Hot deserts- About 15 cm yearly
Cold deserts- About 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

5. 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

6. 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

7. 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

8. Taiga (Coniferous Forest)
Winter- Temperatures range from
-65*F to 30*F
Summer- 20*F to 70*F
Annual precipitation is about 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

9. 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
