The Worlds Biomes and Ecological Organization.

• Yea!

2
Background

• Ecology is the study of living things in their
  environment and how they affect each other.

3
Background

• Ecological Organization
• Living things can be studied at six different
  levels
• INDIVIDUAL
• An organism belonging to a particular species.

4
Background

• Ecological Organization
• POPULATION
• A group of organisms of the same species living
  together in a specific area.
• The total count of individuals within a group.

5
Background

• Ecological Organizations
• COMMUNITY
• Made up of populations of different species
  living together in the same area.
• These organisms usually interact and depend on
  each other.

6
Background

• Ecological Organizations
• ECOSYSTEM
• A system in which biotic (living) organisms
  interact with each other and their abiotic
  (nonliving) environment.
• Abiotic environments include things such as
  sunlight, soil, moisture, temperature,and
  nutrients.

7
Background

• Ecological Organization
• BIOME
• More on this in a minute.

8
Background

• Ecological Organization
• BIOSPHERE
• The sum of Earths biomes.
• The living part of the planet.
• Extends from just above to just below Earths
  surface.

9
Biomes

• A group of ecosystems with similar climates and
  organisms.
• Ecosystem - All the living and non-living things
  that interact in an area

10
Biomes

• Biomes are the regions of our planet which are
  best be defined by their climate, plant life and
  animal life.

11
Biomes

• What is the most important factor in forming or
  creating a biome?
• C.D.

12
Biomes

• Climate!
• Temperature and rainfall determine a biome.
• Why?
• C.D.
• Level sticks

13
Biomes

• How many Biomes are there?
• Scientists argue on the exact number, or
  different types of biomes in existence.
• We are going to lump them into about 9.

14
Biomes

• Rain Forest Biomes
• A forest that receives more than 2.5 meters (8
  feet) of rain each year.
• Tropical
• Warm regions, close to the equator
• Temperate
• Land along the northwest coast of the US

• Desert
• An area that receives less than 25cm of rain each
  year.

22
Biomes

• Grasslands
• An area that receives between 25cm and 75cm of
  rain each year.
• The main vegetation is grass or type of grass
  plants.

25
Biomes

• Deciduous Forest
• Has at least 50cm of rain each year.
• Forests in which the trees lose their leaves each
  year.
• Deciduous means "temporary" or "tending to fall
  off" (deriving from the Latin word decidere, to
  fall off).

Biomes

• Boreal Forest
• Has at least 50cm of rain each year.
• Forests contains Coniferous Trees
• Seeds in cones and leaves shaped as needles
• Winters are very cold.

31
Biomes

• Tundra
• Extremely cold and very dry
• Most soil exist as permafrost.
• Frozen soil

Biomes

• Mountains and Ice
• Mountains pass through several biomes as you
  travel from base to peak
• Ice - well its IceNuff said.
• Penguins and polar bears

35
Biomes

• Freshwater
• Standing water
• Ponds and lakes
• Flowing water
• Streams and Rivers

36
Biomes

• Marine
• We have a whole presentation on that.
