Ecology Unit

Studying life, on the broad scale.

Mr. Roes

Living Environment


The Earth.

A whole lot of it.

That’s the scope of focus for

our unit on ecology.

“The earth is what we all have in common.”

~Wendell Barry


What is ecology
What is Ecology?

  • Ecology is the study of the interactions between organisms and their surroundings.

  • How could you describe what you see here?


Where are all those organisms
Where are all those organisms?

  • The area of the earth where all of the living organisms are found is called the biosphere.

  • Where are the living things found?


Biomes
Biomes

  • We divide up the biosphere into six different types of biomes.

    • Tropical Rainforest

    • Savannah/ Grasslands

    • Desert

    • Temperate Deciduous Forest

    • Boreal Forest

    • Tundra


A biome is an area or a group of areas with a similar climate. Usually, a biome will have the same dominant communities.


Ecosystems
Ecosystems

  • An ecosystem is a collection of all of the organisms that live in a particular place, together with their physical environment.


Community
Community

  • All of the organisms in an ecosystem.

    A community is the total group of organisms living in a distinct area. In a community, there can be hundreds or thousands of different species of organisms, but we don’t include anything nonliving.


Population
Population

The grand total of all of the individuals of a certain species living in one area.

Like communities, populations never include nonliving things!


Organism
Organism

One individual living creature.

In ecology, individual organisms are typically the smallest unit of study focused upon.


The biosphere
The Biosphere

The total area of our planet where life can be found.


Savannah

Tundra

Desert

Grasslands

A biome is an area or a group of areas with a similar climate. Usually, a biome will have the same dominant communities.


Working with a partner organize the following factors in your packet
Working with a partner, organize the following factors in your packet.

The area has four seasons

throughout the year.

Dall Sheep live here.

Grasses and shrubs grow

during the summer

The area doesn’t

Receive much sunlight

Shrubby plants grow

in areas with soil.

Lichen readily grow

on exposed rocks.

The climate is

cold .

There is only a very

thin layer of soil

There are especially

harsh winters here

There is a high

speed of erosion

Arctic squirrels live here

and eat the seeds of

grasses and sedges.

The summer and fall

seasons can become dry

Very fast winds are common

The location is at a high altitude.




Ecosystems1
Ecosystems

  • Why were those ecosystems so different?

  • What forces shaped them to their current states?


Ecosystems2
Ecosystems

  • We can divide the forces that shape an ecosystem into two groups: Biotic and Abiotic.

    • Biotic—Any of the living factors that affect an organism in its environment.

    • Abiotic—The nonliving chemical and physical properties of an environment.
