Dormancy, Hibernation, and Migration

Which of the following is NOT a reason for hibernation: food scarcity, cold temperatures, or fewer clouds that make rain?

• Food scarcity

• Cold temperatures

• Fewer clouds that make rain

• Lack of sunlight

What is the difference between dormancy and hibernation?

• Dormancy is a state of reduced metabolic activity, while hibernation is a specific type of dormancy characterized by deep sleep.

• Dormancy is a period of inactivity, while hibernation is a seasonal sleep that occurs in winter.

• Dormancy refers to a temporary state of sleep, while hibernation is a permanent state of inactivity.

• Dormancy is a phase of growth, while hibernation is a phase of reproduction.

What is the behavior called when animals move from one region to another in response to seasonal changes?

• Migration

• Hibernation

• Estivation

• Foraging

What adaptations do animals have for migration?

• Increased fat storage and changes in feather or fur.

• Ability to fly at high altitudes.

• Enhanced night vision for nocturnal travel.

• Ability to communicate with other species during migration.

What is the significance of migration in the life cycle of certain species?

• It allows them to find food, breed, and avoid harsh environmental conditions.

• It helps them to adapt to urban environments.

• It enables them to increase their population size rapidly.

• It allows them to hibernate during winter months.

What is the primary purpose of hibernation for animals?

• To survive periods of cold and food scarcity.

• To increase their metabolic rate during winter.

• To migrate to warmer climates.

• To reproduce during the winter months.

What is the role of sunlight in the dormancy of plants?

• Sunlight triggers the process of photosynthesis, which is essential for leaf growth.

• Sunlight causes plants to lose their leaves during dormancy.

• Sunlight has no effect on the dormancy of plants.

• Sunlight helps in the absorption of water from the soil.

How do animals prepare for hibernation?

• They typically eat more to build fat reserves.

• They migrate to warmer climates.

• They increase their activity levels.

• They sleep more during the day.

What physiological changes occur in animals during hibernation?

• Increased heart rate, elevated body temperature, and heightened metabolic rate.

• Lowered heart rate, reduced body temperature, and decreased metabolic rate.

• Stable heart rate, normal body temperature, and increased metabolic rate.

• Decreased heart rate, increased body temperature, and stable metabolic rate.

What happens to trees as winter approaches, particularly in relation to sunlight and temperature?

• Trees lose their leaves.

• Trees grow taller and stronger.

• Trees produce more fruit.

• Trees remain unchanged.
