    Migration to a warmer place with more food. Birds fly to areas with abundant food and warmth.

26. Which need is met when a porcupine grows sharp quills?

    Protection from predators. Sharp spines deter animals from attacking or eating them.

27. What need does a camel meet with a hump?

    Energy storage for times with little food. Fat in the hump provides energy when food is scarce.

28. What need is helped when a duck has webbed feet?

    Moving in water to find food and stay safe. Webbed feet push more water for better swimming.

29. Which need is helped when a turtle can pull into its shell?

    Protection from predators. Hard shell shields soft body from danger.

30. What need do cactus spines help meet?

    Saving water and protection from animals. Sharp spines keep animals away and reduce water loss.

31. What need is helped when a turtle has a hard shell?

    Protection from predators. The shell acts as armor against predators.

32. Which change helps a camel meet its needs: a hump or a short neck?

    A hump. Humps store fat for energy, neck length doesn't help survival.

33. Which change helps an animal meet its needs: camouflage color or bright flashing color to hide?

    Camouflage color. Blending in helps animals hide from predators.

34. Which need is met when a chameleon changes color to match its surroundings?

    Protection by camouflage. Matching colors hide chameleons from both predators and prey.

35. Which need is helped when a polar bear has white fur that matches snow and ice?

    Staying safe by hiding (camouflage). White fur blends with snow so predators can't see them.

36. What need is helped when a bird has a beak shaped to crack seeds?

    Getting food. The special beak shape helps crack open seeds for eating.

37. What need does a duck meet with webbed feet?

    Movement in water to find food and stay safe. Webbed feet push water like paddles for swimming.

38. What change helps a squirrel meet its need for food during winter?

    Storing nuts and seeds for later. Squirrels collect food in fall to eat when none is available.

39. Which change helps a duck meet its needs: webbed feet or tiny wings?

    Webbed feet. Webbed feet help ducks swim, tiny wings don't help survival.

40. Which change helps a fish meet its needs: gills or lungs?

    Gills. Gills extract oxygen from water, lungs need air.

41. Which need is helped when a plant has deep roots in a dry place?

    Getting water. Long roots reach water deep underground in dry soil.

42. Which need is helped when squirrels store nuts before winter?

    Having food later. Storing food ensures survival when none can be found.

43. What need do gills help a fish meet?

    Breathing oxygen from water. Gills have special parts that take oxygen from water.

44. What is the need met when a rabbit changes to a white coat in winter?

    Protection by camouflage from predators. White fur blends with snow, making rabbits harder to spot.

45. Which need is helped when a fish has gills?

    Breathing in water. Gills take oxygen from water so fish can breathe underwater.

46. Which change helps a bird meet its needs: a beak or paws?

    A beak. Beaks are shaped for eating, paws are for walking.

47. Identify how webbed feet help a duck meet its needs.

    Swimming to find food and escape danger. Webbing between toes helps push water for efficient swimming.

48. Identify how a thick shell helps a turtle meet its needs.

    Protection from predators and injury. Hard shells shield soft bodies from attacks and harm.

49. What need is helped when an animal has sharp teeth or a strong beak?

    Getting and eating food. Sharp teeth tear meat; strong beaks crack seeds.
