4 multiple-choice questions marked as you go, and 4 written questions with worked solutions. All on Adaptations, interdependence and competition.
Organisms that live in extreme environments, such as high-pressure deep-sea vents or high-temperature volcanic springs, are known as extremophiles. These organisms have adapted to survive in conditions where others would perish. Which of the following is a functional adaptation likely found in such an organism?
Organisms have functional adaptations that help them survive. Which of the following is an example of a functional adaptation mentioned in the syllabus?
Which of the following describes a functional adaptation that allows an organism to survive in an extreme environment?
Organisms exhibit different types of adaptations to survive. A scientist observes a species of desert animal that produces very concentrated urine and only emerges from its burrow at night.
How would these two adaptations be classified according to the syllabus?
Explain how functional adaptations differ from structural adaptations in an organism, and provide one example related to reproduction as mentioned in the syllabus.
Write your answer out first, then check it against the worked solution.
Contrast the biological processes of imprinting and habituation as types of animal behavior that may be observed in a stable ecosystem.

Explain how a species of bacteria could eventually become resistant to a specific antibiotic in a hospital environment where that antibiotic is frequently used.
Write your answer out first, then check it against the worked solution.
Organisms have evolved various adaptations to survive in their specific habitats.
a) Define extremophiles and give an example of an environmental condition they are adapted to survive in.
b) Explain how structural adaptations differ from behavioural adaptations, providing one specific example for each in an animal of your choice.
c) Plants in a woodland often compete for limited resources. Identify three specific factors that plants compete for and explain how being better adapted to capture one of these factors provides a survival advantage.
