Science Revision Worksheet Grade 5 …… Name: _____________ Fill in the blanks: 1. Water evaporates from the leaves of a plant and returns to the atmosphere in a process called ________________________. 2. The ________________cycle is a continuous circulation between the soil, organisms, and air. 3. Rain water that flows over Earth's surface is called. This water gathers in lakes and rivers. 4. A models how energy is transferred in an ecosystem. 5. The source of all energy in a food chain is the. 6. A model of how food chains are connected is called a. 7. A __________________________ eats other organisms for energy. Choose the correct answer: 1. A model of how food chains are connected is called a_______________: a. Food chain b. B. Food web c. C. Energy flow d. D. Energy pyramid 2. All living things use energy and release gas as a waste product. What cycle explains the circulation of these gases? a. Water cycle b. Oxygen-Carbon cycle c. Nitrogen cycle d. Phosphorus cycle 3. Which part of the water cycle includes water vapor gas changing to a liquid? a. Precipitation b. Evaporation c. Condensation d. Transpiration 4. How do animals get nitrogen that is stored in the soil? a. Animals do not take in the nitrogen stored in the soil. b. Bacteria change the nitrogen into a gas that the animals breathe. c. Plants absorb the nitrogen from the soil and animals can eat the plants. d. The animals can eat the soil and absorb the nitrogen through their digestive system. 5. Mr. Hernandez's science class learned that green plants use sunlight, water, and carbon dioxide to make their own food and release oxygen in the process. How can the class explain how animals complete the oxygen-carbon cycle? a. Animals take in the oxygen, but do not release gas as they use energy. b. Animals take in carbon dioxide and use it to make food. c. Animals take in oxygen and release nitrogen as waste. d. Animals take in oxygen and as they use energy, carbon dioxide is released as waste. 6. Which are necessary for plants to produce energy? Select all that apply. a. sunlight b. carbon dioxide c. sugar d. water 7. Why are producers the first organisms in a food chain? a. They prey on all other organisms. b. They receive energy directly from the Sun. c. They are not consumed by other organisms. d. They break down dead plant and animal matter.  8. How does conserving the amount of water we use affect the water cycle? Circle all that apply. a. limits the amount of water we remove from natural waterways b. allows natural water levels to remain at healthy levels c. adds pollution to nearby waterways 9. Animals can directly use nitrogen stored in the soil. a. True b. False 10. Animals take in oxygen and release nitrogen as waste. a. True b. False 11. The water cycle includes water evaporating into water vapor which can form clouds. a. True b. False Answer the following 1. How do producers affect an entire ecosystem? _________________________________________________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ 2. Write an explanation about the role that bacteria play in the nitrogen cycle. ____________________________________________________________________________________ ____________________________________________________________________________________ ____________________________________________________________________________________ 3. James is observing a lake. He wonders how the water in the lake is included in the water cycle. Place the stages of the water cycle in order, starting with the water in the lake. Large water droplets fall to the ground from the clouds. Water vapor cools and condenses on dust particles forming clouds. Energy from the sun causes the water in the lake to evaporate. Water droplets combine in the clouds to form larger droplets. 1) 2) 3) 4) 4. The arrows in a food chain represent the flow of energy and nutrients from one organism to another. Jonathan created this model of organisms that live in the ocean. a. Describe what the arrows in the model represent. _______________________________________________________________________________ _______________________________________________________________________________ b. Identify the original source of energy for the killer whale. ______________________________________________________________________________ ______________________________________________________________________________ c. Identify the predator. _______________________________________________________________________________ d. Identify the first Consumer: ______________________________________________________________________________
