Students should be able to describe different levels of organisation in an ecosystem from individual organisms to the whole ecosystem |
|
What are the different levels of organisation in an ecosystem from individual organisms to the whole ecosystem? |
|
|
|
Students should be able to describe the importance of interdependence and competition in a community. |
|
What is the importance of interdependence and competition in a community? |
|
|
|
Students should be able to, when provided with appropriate information suggest the factors for which organisms are competing in a given habitat |
|
What factors are organisms competing for in a given habitat? |
|
|
|
An ecosystem is the interaction of a community of living organisms
(biotic) with the non-living (abiotic) parts of their environment. |
|
What is an ecosystem? |
|
|
|
To survive and reproduce, organisms require a supply of materials from their surroundings and from the other living organisms there. |
|
What do organisms require to survive? |
|
|
|
Plants in a community or habitat often compete with each other for light and space, and for water and mineral ions from the soil. |
|
What do plants compete for? |
|
|
|
Animals often compete with each other for food, mates and territory.
|
|
What do animals compete for? |
|
|
|
Within a community each species depends on other species for food,
shelter, pollination, seed dispersal etc. If one species is removed it can affect the whole community. This is called interdependence.
|
|
What do species within a community depend on each other for? Habitats of Hamble:
Students go to designated spots around the school (give students a stop watch and a time limit), e.g. behind Durban. At each location students are to note down the different organisms living there and what they compete for. How would the removal of one species impact the other species living here?
OR
Habitats of the World:
Set up stations around the classroom with a different habitat at each (e.g. arctic, rainforest, savannah, etc.)
At each station have a large photo of the environment and some example food webs. Students are to note down the different organisms living there and what they compete for. How would the removal of one species impact the other species living here? |
|
|
|
A stable community is one where all the species and environmental factors are in balance so that population sizes remain fairly constant. |
|
What is a stable community? |
|
|
|
Students should be able to extract and interpret information from charts, graphs and tables relating to the interaction of organisms within a community. Extract and interpret information from charts,
graphs and tables.(MS) |
