Migration is best described as which of the following?

• A. Daily movements within a single habitat.
• B. Seasonal movement between habitats to find food, breeding sites, or favorable climates; can be long-distance.
• C. Permanent residency with no movement.
• D. Moving only during the night to avoid heat.

Answer: (B)

Migration involves periodic, often long-distance travel from one habitat to another in response to changing resources or conditions. This seasonal movement lets animals access food, find suitable breeding sites, or seek favorable climates, and it can cover great distances. It’s different from staying in one place permanently or just moving around within the same area for daily foraging. It also isn’t defined by moving at night to avoid heat, which is a timing pattern rather than a seasonal, cross-habitat journey. Examples include birds that fly to different regions each year and herd species that shift ranges with the seasons to follow rainfall or greener grazing spots.
