Practice questions testing deep understanding of adaptations, population growth curves, and species interactions.
Q1. A biologist studies two different populations of the same species of mouse. Population A lives in a harsh, fluctuating environment with high predation. Population B lives in a highly stable environment with no predators. Predict whether Population A or B is more likely to exhibit an "r-selected" reproductive strategy (producing many small offspring with no parental care) and explain why based on evolutionary survival.
Q2. Assertion (A): The relationship between a clownfish and a sea anemone is an example of Commensalism. Reason (R): The clownfish gains immense protection by living among the anemone's stinging tentacles (benefiting the fish), while the sea anemone is neither harmed nor significantly benefited by the presence of the fish.
