Ecology Biomes

• Mr. DeGuzman
• Biology A

3
What affects climate?

• Climate in an area is affected by two main things
• Direct sunlight (heat)
• Precipitation

4
Biomes

• There are two main types of biomes
• Land
• Aquatic (water)
• We will speed through both today

5
Land Biomes

• Land biomes
• Tropical Rain forest
• Tropical Dry Forest
• Tropical Savanna
• Desert
• Temperate Grassland
• Temperate Woodland and Shrubland
• Temperate Forest
• Northern Coniferous Forest
• Boreal Forest or Taiga
• Tundra

Aquatic biomes

• There are 3 main types of aquatic biomes.
• Can you guess what might be the difference in the
  water for each biome?
• Salt content
• The 3 main types of aquatic biomes
• Freshwater
• Marine (saltwater)
• Estuaries

Tundra

• Tundra
• Located near the poles
• Treeless biome covered by moss, lichens, and
  grasses
• Permafrost a layer of permanently frozen subsoil

Boreal Forest

• Boreal Forest or Taiga
• Covered by coniferous (cone bearing) trees.
• Bears, wolves, moose, elk are some of the typical
  animals

• Plants change during the seasons (leaves change
  color)

Grasslands

• Grasslands
• Most of the rainfall occurs in one part of the
  season
• Hot summers, cold winters

Tropical Rain Forest

• Tropical rain forest
• Receive 200-400 centimeters of rain a year
• Constant temperature.
• Home of the most types of animals than any other
  biome. Many colorful

Deserts

• Deserts
• Less than 25 cm of rain falls a year
• Both plants and animals must be able to retain
  moisture.
• Birds, lizards, snakes, insects are typical
• Cactus and sagebrush sparsely cover the area

• Includes all of the ocean
• Marine biomes are divided into 4 subcategories
• Intertidal zone
• Neritic zone
• Open-sea zone
• Deep-sea zone

Estuaries

• Estuaries are the boundaries between freshwater
  and saltwater.
• Since it is a mix of the two, a variety of
  organisms can be supported.
• Examples of estuaries
• Delta, swamp, lagoon
