Which of the following scenarios best illustrates Liebig's Law of the Minimum?
Which of the following scenarios best illustrates Liebig's Law of the Minimum?
- An animal adjusts its behavior to avoid extreme temperatures during the hottest part of the day.
- A plant species thrives in a nutrient-rich environment, displaying vigorous growth and reproduction.
- The distribution of a fish species is limited by the availability of oxygen, even when other resources are abundant. (correct)
- Different plant species in a community compete for sunlight, with taller plants overshadowing smaller ones.
How does the surface area-to-volume ratio affect an organism's heat exchange with its environment?
How does the surface area-to-volume ratio affect an organism's heat exchange with its environment?
- A larger surface area-to-volume ratio increases heat exchange with the environment. (correct)
- The surface area-to-volume ratio has no significant impact on heat exchange.
- A larger surface area-to-volume ratio decreases heat exchange with the environment.
- A smaller surface area-to-volume ratio increases heat exchange with the environment.

Which of the following strategies is an example of tolerance, rather than avoidance, in response to environmental stress?
- A bird migrating to warmer climates during the winter months.
- A plant growing in a saline soil accumulating solutes in its cells to maintain osmotic balance. (correct)
- A desert lizard seeking shelter under a rock during the hottest hours of the day.
- An insect entering a state of diapause to survive unfavorable conditions.
