ORGANISM DISTRIBUTION
Why do organisms live in different areas?
Organisms are distributed across different habitats dependant on environmental factors.

- Temperature
- Availablity of water
- Availablity of oxygen and carbon dioxide
- Availablity of nutrients
- Amount of light
These factors lead to different areas hosting different amounts of the same organism.
The two ways to study distribution are-
- Measuring the amount of an organism in an area using quadrats and then drawing a comparison with the amount in another area
- Studying how distribution changes across an area by placing quadrats across a transect
Using Quadrats
1) Place a 1m*1m square quadrat on…
