October 28th, 2014 4C Habitat Unit Test Questions 1. What is a habitat? A place where animals and plants live. A habitat has everything that a living thing needs to survive. 2. What is a community? A group of plants, animals, people living in the same area or have something in common. 3. What is a population? The number of living things in a specific area. 4. AN OMNIVORE is a living thing that eats both plants and animals. One example of this is a BEAR. 5. A CARNIVORE is a living thing that eats only animals. One example of this is a LION. 6. A HERBIVORE is a living thing that eats only plants. One example of this is a DEER. 7. What is the difference between a producer and a consumer? Producer: a living thing that makes its own food. This is a type of plant. Consumer: a living thing that cannot make its own food so it must hunt for food. 8. What is the difference between a prey and a predator? Give me 1 example for each.

DECOMPOSERS break down plants and animals into nutrients. Two examples of these are BACTERIA and FUNGI. 11. Why are decomposers important? Decomposers are important because they make nutrients for the soil. Healthy soil is important for plants to grow. Without plants there would be a problem with many food chains. 12. What is a food chain? How is energy part of a food chain? Energy is passed from one living thing to the next each time that an animal is eaten. For example, when the rabbit eats the grass it gets energy from the grass. When the eagle eats the rabbit it gets all the energy that the rabbit had. The energy continues to be passed for the whole food chain. 13. Make one example of a food chain and label all of the parts: producer, consumer, herbivore, omnivore, carnivore and decomposer. You do not have to draw the animals, you can just write the animal name. Students should have examples of food chains in their copy books. 14. Look at the 2nd animal in the food chain that you just made. Explain what would happen to the food chain if this animal became extinct from this habitat. If this animal was removed from the food chain it would affect the lives of the rest of the animals that come after it. For example, if the eagle eats the rabbit but the rabbits become extinct in the habitat, the eagle will be affected. It will have to find something new to eat in that habitat or it will die. 15. What is a structural (physical) adaptation? Copy book October 28th, 2014 4C 16. Give 1 example of a structural adaptation. A polar bear has fur on the bottom of its paws so that it does not slip on the ice. 17. CHLOROPHYLL is the green material in plants that allow them to produce their own food. 18. EXTINCTION is when the living thing used to exist but no longer does. One example of this type of animal is __________________. 19. ENDANGERED is when a living thing is very close to not existing anymore but there are still some left on earth.
