Define “environmental pressure” and provide two examples. (2 marks)
Question 2 ⭐️⭐️
Explain how a prolonged drought might affect the abundance of plant species in an ecosystem. (3 marks)
Question 3 ⭐️⭐️⭐️
Which of the following is the best example of an environmental pressure leading to a change in species diversity? (1 mark)
a) A species of bird migrating to a new habitat with a similar climate.
b) A predator population decreasing due to lack of prey.
c) A new pesticide reducing insect populations in an agricultural area.
d) A species of fish developing a mutation that changes its color.
Question 4 ⭐️⭐️⭐️
Analyze the impact of industrial pollution on aquatic species diversity and abundance. (4 marks)
Question 5 ⭐️⭐️⭐️🔥
Evaluate the role of natural disasters, such as wildfires, in shaping species diversity and abundance in terrestrial ecosystems. (6 marks)
Adaptations
Inquiry question: How do adaptations increase the organism’s ability to survive?
Question 6 ⭐️
Define structural, physiological, and behavioral adaptations, and provide one example of each. (2 marks)
Question 7 ⭐️⭐️
Explain how the thick fur of polar bears helps them survive in cold environments. (3 marks)
Question 8 ⭐️⭐️⭐️
Which of the following is an example of a physiological adaptation? (1 mark)
a) A bird migrating to a warmer climate in winter.
b) A lizard basking in the sun to increase body temperature.
c) A camel storing fat in its hump to survive without food for long periods.
d) A frog’s bright coloration warning predators of its toxicity
Question 9 ⭐️⭐️⭐️
Compare and contrast how desert plants and deep-sea fish have evolved adaptations to survive in their respective extreme environments. (4 marks)
Question 10 ⭐️⭐️⭐️🔥
Evaluate the significance of convergent evolution in the development of adaptations, using marsupial and placental mammals as examples. (6 marks)
Theory of Evolution by Natural Selection
Inquiry question: What is the relationship between evolution and biodiversity?
Question 11 ⭐️
Which of the following best defines biodiversity? (1 mark)
a) The variety of living organisms in a specific area

c) The genetic makeup of individuals in a population
d) The interaction between different species in an ecosystem
Question 12 ⭐️⭐️
How does natural selection contribute to the evolution of new species? Provide an example. (3 marks)
Question 13 ⭐️⭐️⭐️
Explain how the process of speciation can lead to increased biodiversity over time. (4 marks)
Question 14 ⭐️⭐️⭐️
Describe how genetic variation within a population contributes to the evolution of species and impacts biodiversity. (5 marks)

Inquiry question: What is the evidence that supports the Theory of Evolution by Natural Selection?
Question 16 ⭐️
Define natural selection and give one example of it occurring in nature. (2 marks)
Question 17 ⭐️⭐️
Which of the following provides evidence for the theory of evolution? (1 mark
a) The fossil record showing changes in species over time
b) The distribution of species based on climate
c) The fact that all organisms are made of cells
d) The similarities in size and shape of unrelated species
Question 18 ⭐️⭐️⭐️
Discuss the role of homologous structures in supporting the theory of evolution, providing an example.
(4 marks)
Question 19 ⭐️⭐️⭐️
Which of the following is evidence of evolution by natural selection?
a) The distribution of species across continents.
b) The presence of vestigial structures in organisms.
c) The similarity in DNA between species.
d) All of the above.
