Thinking and Investigating 1. What is adaptation? Give two examples of adaptation that you observed in your habitat
study. One example should relate to an animal and one to a plant. For each example explain how you think the adaptation allows the organism to survive in its specific habitat.
2. What is competition? Give two examples of competition that you observed in your habitat study. Explain how you used your observations to investigate competition within your chosen study area.
3. What is interdependence? Give an example of interdependence that you observed while carrying out your habitat study. Give examples of interdependence that you would expect to observe in (a) a polar ecosystem (b) a marine ecosystem (c) a tropical rainforest.
4. A ranger in a national park observes a decline in the number of buttercups in a wild meadow. Suggest how a habitat study could be used to investigate this issue.
5. A scientist is asked to study the numbers of frogs in a large marshy area. Outline how they could conduct this study under the following headings: (a) Planning
(b) Choosing study sites (c) Choosing a suitable time of year to conduct the study (d) Equipment used (e) Presentation of findings How do you think that the number of frogs in the marsh would be influenced by: (i) adaptation, (ii) competition and (iii) interdependence?
