Study Guide for Green Lab Book Exam
This study guide does not cover all of the material on your test. This review is meant to be a starting point to help you remember the major ideas that we covered in class. Be sure to also review the information in your notebook, lab book, and returned quizzes and tests.
1. What is ecology? The scientific study of how living things interact with each other and their environment.
2. What are the ABCs of Ecology? Abiotic, Biotic, and Cycles
3. What are the characteristics and needs of living things? Needs: Water, food, sunlight, shelter Characteristics: movement, respiration, nutrition, irritability, growth, excretion, reproduction, death
4. Arrange the following from smallest to largest: population, biome, organism, community, ecosystem. Organism, population, community, ecosystem, and biome.
Ecosystems:
1. Define the following: a. niche- the role of an organism in an ecosystem. b. decomposer- an organism that feeds on and breaks down dead plant or animal matter. c. producer- an organism that captures energy from sunlight and transforms it into chemical energy cccccccc cthat’s stored in energy-rich carbon compounds. Producers are a source of food for other organisms. d. consumer- a living thing that gets its energy by eating other living things in a food chain. e. limiting factor- a factor or condition that prevents the continuing growth of a pop. in an ecosystem
2. What do the arrows in food chains or webs mean? Eaten by, gives energy to
3. The level of the energy pyramid with the most energy contains what type of organisms? How much energy is transferred each time you move up a level? The level that has most energy are the producers which are plants. 10% of the energy is transferred each time NJyou move up a level.
