Transcript of Scientific understandings of outdoor environments

Scientific understandings of outdoor environments
Interrelationships between biotic and abiotic components
Biotic = Living plants and animals
Abiotic = Non-living components of the natural environments (rocks, sunshine, water, soils etc.)
Components tasks
1. In your Glossary write definitions for both 'Biotic' and 'Abiotic' components
So they're the components.. but how do they interact in these environments?
1. Class example.. including an abiotic component
Scientific understandings of specific outdoor environments, including:
- Interrelationships between abiotic and biotic components
Key Knowledge Point:
2. Draw up and complete the following table specifically for 3 of the environments we have studied this term (3 separate tables)
2. Go to http://www.gould.org.au/foodwebs/kids_web.htm and figure out your own
3. Draw up a food web or chain for one of the ecosystems present in the environment you have been studying this term.
What issues can arise with these components?
A change of vegetation in a forest results in the removal of habitat for animals which in turn impacts food levels and breeding cycles of some animals.
Cloud cover can limit interactions between biotic and abiotic components. An increase in cloud cover can limit sunlight, reducing the ability for plants to grow
What other links can you make between biotic and abiotic components of your environment?
Even the webs are webbed together..
Every biotic component relys on an abiotic component to survive and grow
No subsystem can exist in isolation - aquatic, land fauna, flora..
..Hence even minimal human impacts having drastic and widespread effects
Complete the forest food web tasks
Copy the following tables into your books
