What do these pictures have in
common?

Activity
Get into 4 groups. Each member must perform, but elect a team leader. He is going to help guide
you. Designate a task to each member of your team.
•
Chose a picture:group 1- swamp
group 2- desert
group 3- arctic
group 4- coral reef
•
Using the materials provided
Chose 1 animal that lives there and build the home it would live in, eg. An ants lives in an ant hill.
This place where the organism lives is called its habitat.
Is this organism the only one of its kind there? Are there others?
_______________________________________________
If there are others of its kind, this is called a species. The number of this species is called the
population. Populations interact to form habitats.
Are there other organisms that live in this environment? If yes, what organisms?
_______________________________________________.
Add these organisms to your project. (you may have to either cut out, build or place the organism
in position)
This is now called an ecosystem. An ecosystem is
Place your ecosystem at various positions in the lab. This is now called a Biome. Biomes are a
number of ecosystems where several habitats exist, such as Earth.
In the habitat are there only living organisms? If No, list some other non-livings things (called
Abiotic factors) that the living things (biotic) need to survive.
______________________________________________________________________________
Add/build as many of these in your habitat/ecosystem.
Are there any other factors that you know affects the lives of these living organisms but cannot
draw or build it? ______________________________________________________________
• Because these organisms are living in a
habitat and no two organisms can live in
the same habitat, relationships develop:
• Mutualism
• Parasitism
• commensalism

A Habitat is _________________________________
It may consist of __________ and non-living factors.
Living organisms are called ___________ and non-living are called
____________.
4. These non-living factors affect the survival of the living organisms. These
factors are:
___________________________________
A habitat can make up an_____________ such that a number of
P___________ live in that ecosystem.
5. Ecosystems can exists as neighbours to make _________.
6. If an ecosystem is like a linked chain, and any of the components that make
up an ecosystem is removed, what do you expect will happen?

7. From your ecosystem establish examples for each type of relationships that
exist.
Mutualism –
Parasitism –
Commensalism –
8. Identify the biotic and abiotic factors in your model.
