Unit 2: Organisms and their environment
In this unit students study environmental factors common to all habitats and investigate structural and physiological adaptations of organisms to particular ecological niches. Plant growth responses are also investigated. Behavioural and reproductive adaptations are used to study individual and group behaviour of animals. Components, relationships and energy flows within ecosystems are studied. Techniques used to monitor environmental change and maintain ecosystems are investigated. Students are required to conduct fieldwork.
Outcome 1
On completion of this unit the student should be able to explain and analyse the relationship between environmental factors, and adaptations and distribution of living things.
Outcome 2
On completion of this unit the student should be able to design, conduct and report on a field investigation related to the interactions between living things and their environment, and explain how ecosystems change over time.
