Slide Show #1

Getting Started… (p.4)

• Close your eyes and imagine that you are standing in a forest.

• Now, list at least 5 things that you “see”.

• Next, describe the local conditions (eg. land features, temperature, etc.) of your forest setting.

Getting Started (con’t)

We will know identify those parts of your ecosystem as Living or Non-Living.

• How would you define a living thing?• A living thing is something that shows or has

shown the signs of life. That is, anything that is either alive or dead is classified as a living thing.


• From your thought web, what signs of life do all of the living things have in common?• All living things:

• Grow• Reproduce• Move• Take in or produce food• React to things in their environment• Have cells• Have a special chemical make-up


• How would you define a non-living thing?• A non-living thing is something that will never show

the signs of life.• Examples:

• What is the difference between a rock and a dead rabbit ?• A rock NEVER showed the signs of life and never will.

A dead rabbit, however, was once alive and therefore showed the signs of life.

• To distinguish between these, scientists classify living things as either dead or alive. So, the dead rabbit is actually a living thing!


• From your forest list, classify each thing as either living (L) or non-living (NL). Share your results with the class.

Living Non-Living

Using your forest lists, describe how the living things interact with each other, the non-living things, and the local conditions. An example is done for you.

Local Conditions

A bird builds a nest in a tree.

A bird perches on a rock.

Some birds fly south in the winter (too cold).


• What we have described is a forest ecosystem.

• an ecosystem is a group of interacting living and nonliving things.

Section 1.1: Types of Ecosystems

• Read pages 8-9 in your text.• An organism is…

• any living thing.• Example:

• Adaptations are…• Inherited characteristics that help organisms survive

in their environment.• Example:

• An habitat is..• The particular place that an organism lives.• Example:

Types of Ecosystems (con’t)Abiotic and Biotic Parts of the Environment (p.8)

• Biotic Factors are…• The living parts of an organism’s environment.• Example:

• Abiotic Factors are…• The non-living parts of an organism’s

environment.• Example:

• Identify the biotic and abiotic parts of this pond ecosystem.

Types of Ecosystems (con’t)Studying Ecosystems (p.9)

• An ecosystem is not defined by its geographic size; they can be very small (e.g., a rotting log) or very massive (e.g., Atlantic Ocean).

• Therefore, there are many, many different ecosystems throughout the province, country and world.

Types of Ecosystems

Examples of ecosystems within Newfoundland and Labrador. Include:

(i) ocean and coastline

(ii) forest

(iii) freshwater

(iv) arctic
