Biomes (Terrestial)
An Interdependent system of plants, animals and land
Large regions with similar Ecosystems
Tundra Taiga Desert Savanna Grassland Temperate forest Temperate rain forest Tropical rain forest

Biomes of the World
Biomes: Characterized by their
dominant vegetation & also by animals adapted to that environment
Distribution of biomes is determined mostly by temperature & rainfall

![Page 6: What Are Biomes?. Biomes (Terrestial) An Interdependent system of plants, animals and land Large regions with similar Ecosystems Tundra Taiga Desert Savanna](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bfc71a28abf838ca7947/html5/thumbnails/6.jpg)
Tropical Rainforests
Occur near the equator Warm temperatures Days 11 – 12 hours
long Rainfall is variable Very biodiverse (up to
300 species of trees) Poor soil

Tropical Rainforest
![Page 8: What Are Biomes?. Biomes (Terrestial) An Interdependent system of plants, animals and land Large regions with similar Ecosystems Tundra Taiga Desert Savanna](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bfc71a28abf838ca7947/html5/thumbnails/8.jpg)
Savannas
Grasslands with scattered trees
Can be temperate or tropical
Grasses main vegetation
Animals include: giraffes, zebra, antelope, baboons, lions, cheetahs
![Page 9: What Are Biomes?. Biomes (Terrestial) An Interdependent system of plants, animals and land Large regions with similar Ecosystems Tundra Taiga Desert Savanna](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bfc71a28abf838ca7947/html5/thumbnails/9.jpg)

Deserts
Hot during the day, cold at night
Under 30 cm of rain per year
Large deserts found near 30o N and 30o S latitude
![Page 11: What Are Biomes?. Biomes (Terrestial) An Interdependent system of plants, animals and land Large regions with similar Ecosystems Tundra Taiga Desert Savanna](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bfc71a28abf838ca7947/html5/thumbnails/11.jpg)
Deserts
Desertification: conversion of other biomes (especially savannas) to deserts
Is a major ecological problem
Plants include yucca & cactus
Animals include snakes, birds, insects, lizards, rodents
![Page 12: What Are Biomes?. Biomes (Terrestial) An Interdependent system of plants, animals and land Large regions with similar Ecosystems Tundra Taiga Desert Savanna](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bfc71a28abf838ca7947/html5/thumbnails/12.jpg)
Chaparral
Region of dense spiny shrubs
Mild, rainy winters & long, hot, dry summers
Vegetation is adapted to periodic fires
Animals include deer, fruit eating birds, seed eating rodents, lizards, & snakes
![Page 13: What Are Biomes?. Biomes (Terrestial) An Interdependent system of plants, animals and land Large regions with similar Ecosystems Tundra Taiga Desert Savanna](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bfc71a28abf838ca7947/html5/thumbnails/13.jpg)

Temperate Grasslands
Are mostly treeless except along rivers & streams
Keys to persistence of grasslands: seasonal drought, fires & grazing by large mammals
Amount of annual rainfall determines the height of the grassland vegetation
![Page 15: What Are Biomes?. Biomes (Terrestial) An Interdependent system of plants, animals and land Large regions with similar Ecosystems Tundra Taiga Desert Savanna](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bfc71a28abf838ca7947/html5/thumbnails/15.jpg)
Temperate Deciduous Forests
Grow in latitudes between 35o and 50o
Areas must have sufficient moisture to grow trees
Deciduous: leaf bearing trees (ex: oak, maple, cherry, hickory)
Cold winters, hot summers
![Page 16: What Are Biomes?. Biomes (Terrestial) An Interdependent system of plants, animals and land Large regions with similar Ecosystems Tundra Taiga Desert Savanna](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bfc71a28abf838ca7947/html5/thumbnails/16.jpg)
Temperate Deciduous Forests
High precipitation year round
Trees have a distinct annual rhythm
Rich soil Animals include deer,
bear, squirrels, raccoons, birds, insects
![Page 17: What Are Biomes?. Biomes (Terrestial) An Interdependent system of plants, animals and land Large regions with similar Ecosystems Tundra Taiga Desert Savanna](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bfc71a28abf838ca7947/html5/thumbnails/17.jpg)
Taiga: Coniferous Forests
Conifers: cone bearing trees (ex: pine, spruce, fir)
Taiga: northern coniferous forests
Taiga is cold, but many coniferous forests are temperate

Tundra
Near the North Pole Little vegetation, but
mostly mosses, lichens, & small shrubs
Very cold Permafrost: layer of soil
that remains permanently frozen
![Page 20: What Are Biomes?. Biomes (Terrestial) An Interdependent system of plants, animals and land Large regions with similar Ecosystems Tundra Taiga Desert Savanna](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bfc71a28abf838ca7947/html5/thumbnails/20.jpg)
Tundra
Very little precipitation, but swampy in the summer
Animals include: artic fox and hare, insects (in summer), musk oxen, caribou
