Which organism would most likely come after the snake in the food chain?
  1. Pictograph - Larva
  2. Pictograph - Eagle

Grade 5 Adaptations and Behavior
The main purpose of an adaptation is to
  1. help an animal survive.
  2. get food.
  3. provide a habitat.
  4. change the animal's appearance.
Grade 5 Skin, Skeleton, and Muscles
The bones in the spine are
  1. cartilage.
  2. little bones.
  3. ribs.
  4. vertebrae.
Grade 5 Food Chains and Webs
Imagine that pollution caused all the plants in an aquatic food chain to die. Would this affect the population of the largest fish?
  1. Yes, because the largest fish need to eat plants to supplement their diet.
  2. Yes, because all the food energy in the chain begins with the plants.
  3. No, because the largest fish are big enough to survive a change in the ecosystem.
  4. No, because only the smallest fish depend on the plants for survival.
Grade 5 Cell Structure and Function
How can a student distinguish a plant cell from an animal cell?
  1. If the cell has a cell wall, it must be from a plant.
  2. If the cell has cytoplasm, it must be from a plant.
  3. If the cell has a nucleus, it must be from an animal.
  4. If the cell has a cell membrane, it must be from an animal.
Grade 5 Cell Structure and Function

  4. cell membrane
Grade 5 Cell Structure and Function
What part of a plant cell controls the activity of the cell?
  1. cell membrane
  2. nucleus
  3. chloroplast
  4. cell wall
Grade 5 Cell Structure and Function
A cell is the
  1. storage space.
  2. tiny unit of a living thing.
