The World’s Biomes and Ecological Organization.
Yea!
Background…
• Ecology is the study of living things in their environment and how they affect each other.
Background…
• Ecological Organization– Living things can be studied at six different
levels:
• INDIVIDUAL:– An organism belonging to a particular species.
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.
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.
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.
Background…
• Ecological Organization
• BIOME:– More on this in a minute….
Background…
• Ecological Organization
• BIOSPHERE:– The sum of Earth’s biomes.– The living part of the planet.– Extends from just above to just below Earth’s
surface.
Biomes
• A group of ecosystems with similar climates and organisms. – Ecosystem - All the living and non-living
things that interact in an area
Biomes
• Biomes are the regions of our planet which are best be defined by their climate, plant life and animal life.
Biomes
• What is the most important factor in forming or creating a biome?
– C.D.
Biomes
• Climate!– Temperature and rainfall determine a biome.
• Why?
– C.D.– Level sticks
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.
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

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

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

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.

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 it’s Ice…’Nuff said.
• Penguins and polar bears
Biomes
• Freshwater – Standing water
• Ponds and lakes
– Flowing water• Streams and Rivers
Biomes
• Marine – We have a whole presentation on that.
