This document describes the major land biomes on Earth, including forests, grasslands, deserts, and tundra. Forest biomes include temperate deciduous forests, coniferous forests, and tropical rainforests. Grasslands include temperate grasslands, savannas, and tundra biomes include polar tundra and alpine tundra. Each biome is defined by characteristic climate conditions like temperature and rainfall as well as the types of plants and animals found there.

1. Land Biomes
Por: Isa O y Aleja

2. Introduction:
 Differentecosystems are home to
different kinds of organisms, certain ones.
There are different kinds of certain places
and the scientific name is ¨Biomes¨, Which
means: A large region characterized by a
specific type of climate and certain types
of plants and animal communities.

3. This map shows some of the
major land biomes on Earth.

4. Forest Biomes:
 Temperate Deciouous Forest
 Caniferous Forest
 Tropical Rain Forest

5. Temperate Deciduous Forest
 Characteristics:
 In forests, plants growth happends in layers. The leafy
tops of the trees reach high above the forest floor, where
the leaves can get sunlight.
 Woody shrubs catch the light that filters trhough the
trees.
 Ferns and mosses are scattered across the firest floor.
Flowering plants often bloom in early spring, before the
trees grow new leaves.
 The word deciduous comes fron the Latin word taht
means ¨ to fall off¨

6. Average
Yearly Rainfall:
75-125 cm
Average
tempetures:
S: 28°C
W: 6°C

7. Coniferous Forest:
 Characteristic:
 These Conifer leaves are adapted to conserve
water.
 A coniferous forest is home to many insects and to
birds that eat those insects.
 Hervivores that live in thise forest include deer,
moose, porcuponines, and squirrels.

8. Average Yearly Rainfall:
35-75 cm
Average Temperatures:
S: 14°C
W: -10°C

9. Tropical Rain Forest
 Characteristics:
 Trees from a continuous green roof, or canopy
that may exted 60 m above the forest floor.
 Woody vines climb the tree trunks to reach
sunlight.
 Little light reaches the ground. Low-growing
plants in the rain forest don´t need a lot of light.

10. Average Yearly
Rainfall:
Up to 400 cm
Average
Temperatures:
Day: 34°C
Night:20°C

11. Grasslands
 Temperate Grasslands
 Savannas

12. Temperate Grasslands:
 Characteristics:
 Temperate grasslands plants includes grasses and
other flowering plants.
 Temperate Grasslands have few trees.

13. Average yearly rainfall:
25-75 cm
Average Tempetures:
S: 30°C
W: 0°C

14. Savannas:
 Characteristics:
 A grassland that often has scattered trees and
taht is found in tropical and subtropical areas
where seasonal rains, fires, and drought happend.
 During dry seasons, savanna grasses dry out and
turn yellow.

15. Average Yearly Rainfall:
150 cm
Average tempetures:
Dry: 34°C
Wet: 16°C

16. Desert:
 Characteristics:
 A region that has little or no plant life, kong
periods without rain and extreme temperatures;
usually found in hot climates.
 Deep-rooted plants can reach groundwater as
deep as 30 cm.
 Some flowering plants bloom, bear seeds, and die
within a few weeks after a heavy rain.
 Most living things have something special to
survive in the desert.

17. Average Yearly
Rainfall:
Less than 25 cm
Average Tempetures:
S: 38°C
W: 7°C

18. Tundra:
 A treeless plain found in the Artic, In the Sntartic, or
on the tops of mountains that is characterized by
very low winter temperatures and short, cool
summers.
 Polar Tundra
 Alpine Tundra

19. Polar Tundra:
 Permafrost is the layer of soil beneath the surface.
Soil stays frozen all the time.
Alpine Tundra
o Find at the top of tall mountains, above an
elevation called the tree line. Trees ca not grow
there

20. Rain: 30-50 cm
S: 12°C W: -26°C
Alpine Tundra
Polar Tundra
