Title: The%20World
1The Worlds Biomes and Ecological Organization.
2Background
- Ecology is the study of living things in their
environment and how they affect each other.
3Background
- Ecological Organization
- Living things can be studied at six different
levels - INDIVIDUAL
- An organism belonging to a particular species.
4Background
- 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.
5Background
- 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.
6Background
- 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.
7Background
- Ecological Organization
- BIOME
- More on this in a minute.
8Background
- Ecological Organization
- BIOSPHERE
- The sum of Earths biomes.
- The living part of the planet.
- Extends from just above to just below Earths
surface.
9Biomes
- A group of ecosystems with similar climates and
organisms. - Ecosystem - All the living and non-living things
that interact in an area
10Biomes
- Biomes are the regions of our planet which are
best be defined by their climate, plant life and
animal life.
11Biomes
- What is the most important factor in forming or
creating a biome? - C.D.
12Biomes
- Climate!
- Temperature and rainfall determine a biome.
- Why?
- C.D.
- Level sticks
13Biomes
- 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.
14Biomes
- 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
15Tropical Rain Forest Biomes
16Tropical Rain Forest Biomes
17Temperate rainforest Biomes
18Temperate Rainforest Biomes
19Biomes
- Desert
- An area that receives less than 25cm of rain each
year.

22Biomes
- Grasslands
- An area that receives between 25cm and 75cm of
rain each year. - The main vegetation is grass or type of grass
plants.

25Biomes
- 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).

28Biomes
- 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.

31Biomes
- Tundra
- Extremely cold and very dry
- Most soil exist as permafrost.
- Frozen soil

34Biomes
- Mountains and Ice
- Mountains pass through several biomes as you
travel from base to peak - Ice - well its IceNuff said.
- Penguins and polar bears
35Biomes
- Freshwater
- Standing water
- Ponds and lakes
- Flowing water
- Streams and Rivers
36Biomes
- Marine
- We have a whole presentation on that.
