Which picture correctly shows the direction that energy flows in a food chain? (4.2.A.c) a A b B c C d D 13 A student wants to make a food chain using the organisms shown. Which list shows the correct order of organisms in the food chain? (4.2.A.c) a flower --> insect --> mouse --> snake --> hawk b hawk --> snake --. mouse --> insect --> flower c insect --> flower --> mouse --> snake --> hawk d mouse --> snake --> insect --> hawk --> flower 14 The chart below shows a food that each animal likes to eat. Which animal listed in the chart would be at the top of its food chain in its environment? (4.2.A.c) a fox b insect c snake d hawk 15 Observe the food chain below. What would likely happen to the snake if the plants were removed from the food chain? (4.2.A.d) a The snake population would increase, because there would be more frogs. b The snake population would remain the same and not change at all. c The snake population would increase, because there would be fewer frogs. d The snake population would decrease, because there would be fewer frogs. 16 Look at this picture. Which of these would most likely happen to the rabbit population if it did not rain for a year? (4.2.A.d) a It would get smaller because the grass would die. b It would get larger because the coyotes would move away. c It would get larger because the coyotes would eat something else. d It would not change because the rabbits would find another plant to eat. 17 Look at this simple food chain. Which of these would most likely happen if the coyotes eat too many rabbits? (4.2.A.d) a The rabbits will move to a new area, causing the coyote population to increase. b The number of rabbits will decrease, causing the coyote population to decrease. c The number of rabbits will decrease, causing coyotes to change their feeding habits. d The rabbits will learn to hide from the coyotes, causing the rabbit population to increase.
