The world s biomes and ecological organization

The World’s Biomes and Ecological Organization.

Yea!


Background

Background…

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


Background1

Background…

  • Ecological Organization

    • Living things can be studied at six different levels:

  • INDIVIDUAL:

    • An organism belonging to a particular species.


Background2

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.


Background3

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.


Background4

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.

  • BIOME:

    • More on this in a minute….


Background6

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

Biomes

  • A group of ecosystems with similar climates and organisms.

    • Ecosystem - All the living and non-living things that interact in an area


Biomes1

Biomes

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


Biomes2

Biomes

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

    • C.D.


Biomes3

Biomes

  • Climate!

    • Temperature and rainfall determine a biome.

  • Why?

    • C.D.

    • Level sticks


Biomes4

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.


Biomes5

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

Biomes6

Biomes

  • Desert

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

Biomes7

Biomes

  • Grasslands

    • An area that receives between 25cm and 75cm of rain each year.

    • The main vegetation is grass or type of grass plants.

Biomes8

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).

Biomes9

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.

Biomes10

Biomes

  • Tundra

    • Extremely cold and very dry

    • Most soil exist as permafrost.

      • Frozen soil

Biomes11

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


Biomes12

Biomes

  • Freshwater

    • Standing water

      • Ponds and lakes

    • Flowing water

      • Streams and Rivers


Biomes13

Biomes

  • Marine

    • We have a whole presentation on that.
