Read the question carefully. Re-read if necessary ! Examine every answer choice before you choose your answer. Always double check your work. X - out wrong answers by using process of elimination. Look closely at charts, graphs, maps, and pictures.

Let’s review before the test with a few quick questions. This will help you to recharge before you take the Science test today. 1.Take out a sheet of paper and number it from Use the “RELAX” strategy and write down your answer to each question on your paper. 3.When you are done, check your answers to see how well you did!

1. Use the information below to answer the following: Sheep Challenge Evolution A species of sheep lives on the Scottish island of Hirta. Hirta has plenty of grass for the sheep to eat, and no natural predators of the sheep live on the island. Some sheep have dark wool, and some have light wool. The sheep with dark wool tend to be much larger and stronger than the sheep with light wool. However, researchers have found that in the last 20 years, the sheep with light wool have increased in number. Usually, strength and size help animals survive and breed. A new sheep predator is introduced to the island. Which change to the sheep population will most likely occur first? A. a decrease in the population of sheep with dark wool B. a decrease in the population of sheep with light wool C. an increase in the population of sheep with dark wool D. an increase in the population of sheep with light wool

2. Use the information and the diagram below to answer the following: Partial Forest Food Web The movement of energy and matter through some organisms in a forest ecosystem is shown in this food web. Which food chain best shows the flow of matter in organisms in the food web? A. tick → mouse → red oak B. grass → deer → blue jay C. cranberry bush → deer → coyote D. blue jay → caterpillar → cedar waxwing

3. The diagram below shows some of the feeding relationships in a desert food web. Answer the question below. Which of the following trophic levels is not shown in this diagram? a. producers b. decomposers c. primary consumers d. secondary consumers

4. Which biome is characterized by low temperatures and low amounts of rainfall? a. tundra b. desert c. temperate deciduous forest d. tropical rain forest

5. Which of the following symbiotic relationships is considered parasitic? a. ticks feeding on a dog b. bees transporting pollen from flowers c. pilotfish swimming under sharks d. birds eating the insects from the back of a hippopotamus

6. Single-celled organisms can reproduce and create cells exactly like themselves without combining genes from two different parent cells. When they do this, they use a type of a. asexual reproduction. b. gamete formation. c. natural selection. d. sexual reproduction.
