Living organisms and their environments
Why this, why now
This unit explores ecosystem organisation, biotic and abiotic factors, material cycling, and the role of decomposers. It covers methods for identifying species and measuring their distribution. Emphasis is on selecting appropriate techniques, accurate measurements, sampling, and fieldwork practices.
