Gerwitz New 20/21 Post-test Unit 3: Energy & Matter in Organisms

Explore energy and matter in organisms with this 5th-grade science worksheet. Learn about photosynthesis, food chains, and more!

1.) The diagram includes a producer and a consumer. What do the arrows represent? Matter is transferred from the flower, to the bird, to the sun. Matter is transferred from the sun, to the flower, to the bird. Energy is transferred from the sun, to the flower, to the bird Energy is transferred from the flower, to the bird, to the sun. 2.) Gail puts a green plant in a closed wooden box. She gives it good soil and plenty of water. What will happen to the plant? It will die because living things need oxygen It will die because it will not get any sunlight It will grow slowly because it also needs plant food It will grow fast because it has good soil and water. 3.) A bee collects nectar from a flower. The nectar is taken back to the beehive, where it is made into honey. The honey is used as food for the entire beehive. Where does the energy of the honey originally come from. Bee Flower Sugar Sun 4.) The picture shows the steps that happen during photosynthesis.What is happening at Step 4 in the picture? Sugar is entering the leaf, and water vapor is exiting. Oxygen is entering the leaf, and sugar and oxygen are exiting. Carbon dioxide is entering the leaf, and oxygen is exiting. Water vapor and oxygen are entering the leaf, and carbon dioxide is exiting. 5.) Sort these organisms into producers and consumers. Producers Grass Flowers Algea Trees Consumers antelope baboon lion rabbit 6.) Russ puts three bean plants on a windowsill. He waters the plants daily, measuring in milliliters (mL).The plants are watered the following amounts daily:Plant A – 0 mL,Plant B – 10 mL,Plant C – 25 mL,Plant D – 50 mL.Russ measures the height of the plants every week. This table shows his results in centimeters (cm).Which best describes how much water young bean plants need every day? 0 mL 10 mL 25 mL 50 mL 7.) Fill in the blanks with the correct word Food provides an organism with the matter and energy needed for the growth and repair of body parts. 8.) Match each term to whether it is needed for photosynthesis or produced by photosynthesis. Needed for Photosynthesis Carbon Dioxide Sunlight Water Produced by Photosynthesis Oxygen Sugar (Glucose) 9.) Choose the words that correctly complete the sentence. Plants need air which they take in through stomata. Plants also need water which they absorb through their roots. If plants do not get enough water, their leaves will wilt. If plants do not get any air, they will die. 10.) What is the process that plants use to produce food? Sunlight Chloroplast Photosynthesis Carbon Dioxide 11.) A rabbit, grass, and a fox live in a habitat. What is the movement of energy through the organisms in the habitat? Type these words in order by the transfer of energy:Grass - Fox - Sunlight - Rabbit - Mountain Lion Sunlight Grass Rabbit Fox Mountain Lion 12. ) True or False: Deer transfer energy to predators. True False 13.) True or False: Deer get energy from eating plants that produce energy by performing photosynthesis. True False 14.) True or False: Deer get energy from performing photosynthesis. True False 15.) The diagram shows a process occurring in a leaf.Which of these best describes the diagram? the different layers within leaves of plants the process of photosynthesis how plants use the sun to stay warm how plants use energy to grow and move 16.) Students are doing an investigation using an aquarium to see what would happen to the plants and animals in an ecosystem that did not get enough sunlight. They use the same type, number, and size of plants and fish in each tank. Each tank is given a different number of hours of sunlight each day. What should they measure? the temperature of the water the growth of plants and animals how much food they feed the plants how much water they put in the tank 17.) Organisms in ecosystems interact with one another and with nonliving things. Each has a role. Match the things that interact in ecosystems to their roles. Leaf Producer Bird Predator Beetle Prey Sunshine Source of Energy 18.) Kevan’s class did an experiment on plants in class. The results are shown in the table.Which question was Kevan’s class testing in this experiment? Do plants need air to grow? Do plants need soil to grow? How much water do plants need a week? How many hours of sunlight do plants need a day? Directions: Read the passage then answer the questions that follow. Tristan has two identical plants. He plants one outside in the ground. The other is growing indoors without direct light. Tristan predicts the weight of the carbon dioxide and water taken in by the plant and the oxygen given off by the plant.Tristan notices that a rabbit family has been eating the outdoor plant and that small insects are eating the indoor plant. He sees a fox hunting rabbit, but nothing is eating the insects.The diagrams show Tristan's Plant 19.) Suppose the plant has 2 calories per gram. How many grams of the plant would the rabbit need to eat a day to get 200 calories? Write your answer as a number. 20.) Both plants are growing, but the outdoor plant seems to be growing faster. Which factor is most likely causing the outdoor plant to grow faster? less soil more air less water more sunlight 21. ) What are the two substances that are most important for the growth of the plants? 22.) How does the diagram show these two substances that plants need? 23.) Explain how the weight of a plant can show that matter is moving into plants. Use the diagram as an example.
