1 U3 L5 Managing Resources Study Guide Ecologist Section Date KEY Directions: Use Unit 3 Lesson 5, Managing Resources, to answer the questions. 1. Define Renewable Resource. Include an example. A natural resource that can be replaced as quickly as it is used. Exs: water, trees, fish 2. Define Nonrenewable Resource. Include an example. A natural resource that is used much faster than it can be replaced. Exs: coal, minerals, oil, natural gas 3. Identify each picture as either a RENEWABLE RESOURCE or NONRENEWABLE RESOURCE by writing the correct term next to the picture. Petroleum = Coal = Nonrenew Nonrenew_ Air = Renew Steel = Nonrenew Plants = Renew Aluminum = Nonrenew Sunlight = Renew Fresh Water = Renew

2 4. What are 4 harmful effects of the use of fossil fuels? Oil spills can damage ecosystems Burning fossil fuels can cause air and water pollution Oil spills can harm local fishing or tourism Used products (e.g. plastics) can fill landfills or create litter. 5. What is the difference between stewardship and conservation? Stewardship deals with careful and responsible management of resources; conservation deals with protection and wise use of resources. 6. Your book has at least 6 ways that renewable resources can be conserved. List your favorite 3: 1. Limits on fishing or logging 2. Restocking fish 3. Replanting logged areas 4. Conserving water 5. Reducing use of chemical 6. Reducing use of energy 7. Give three examples how can nonrenewable resources be made to last longer? use CFL light bulbs to use less energy using less electricity needs fewer resources to make the electricity Reduce Reuse Recycle 8. Complete the chart with two advantages and disadvantages for managing natural resources:: Advantage 1. Can reduce the loss of a valuable resource. 2. Can reduce waste 3. Can lead to less pollution Disadvantage 1. Developing new technologies that use fewer resources is expensive 2. Changing people s habits can be hard 3. Recycle can be expensive or inconvenient
