UNIT 1: Interconnectedness of life 1B: INTRODUCTION TO ECOLOGY Roadmap for the year: Unit 1: Interconnectedness of Life 1A Characteristics of Living Things 1B Introduction to Ecology 1C Scientific Method Unit 2: Ecological Biochemistry Unit 3: Cellular Biology: Structure Leads to Function Unit 4: DNA Structure and Cellular Reproduction Unit 5: Gene Expression and Inheritance Unit 6: Evolution and Classification of Living Things Unit 7: Biotechnology, Human Biology, and Disease Themes for the year: How does this unit contribute to your understanding of the following themes? Life on Earth has various Levels of Organization The Structure of Living Things leads to their Function The Big Picture for Unit 1… Science is a body of knowledge and skills acquired through systematic experimentation and observation to describe natural phenomena; or, more simply, it is a “way of knowing”. The process of science helps biologists investigate how nature works at all levels, from the molecules in cells to the biosphere. The existence of life on Earth depends on interactions among organisms and between organisms and their environment. There is a great diversity among living organisms yet there are similar characteristics that all organisms share. What does it mean to be ‘alive’? How can species change over time? How do different organisms get the energy they need to survive? How do Earth’s living and nonliving parts interact to shape ecosystems and affect the survival of organisms? How does energy move through an ecosystem? What is science? Suggested Resources… Note Packet Homework assignments Lab activities Textbook – Biology (Miller and Levine, 2010) (Sections 3.1, 3.2, 3.3, 4.2, 4.4) Directions: Below are check lists of things you should know and things you should be able to do by the end of the unit. Use this tool to help you prepare for the unit assessment. By the conclusion of this unit, you should know the following: 1. Ecology is the study of organisms and their interactions with the environment. 2. The environment is a system of interdependent components with living (biotic) and non-living (abiotic) factors. 3. There is a hierarchy of complexity into which living things are organized, from the biosphere to the atoms that make up cells. 4. There are a variety of different largescale ecosystems called biomes each with characteristic flora and fauna; Livingston, NJ is part of a temperate deciduous forest biome. 5. The primary source of energy for most ecosystems is the sun. 6. A food web consists of interconnected food chains. 7. An organism’s role in the ecosystem is its niche. A species is a group of organisms that can breed to produce fertile offspring. 8. Understand how life can be studied at different levels. By the conclusion of this unit, you should be able to do the following: 1. Describe the study of ecology, the components of an ecosystem, and the methods used to study ecology. 2. Explain how biotic and abiotic factors influence an ecosystem, focusing on Livingston’s temperate deciduous forest biome. 3. Distinguish between the varying levels of ecological hierarchy. 4. Compare and contrast the terms producer, consumer, and decomposer and identify how each obtains energy and nutrients. a. Explain why nutrients are important in living systems. b. Identify components of food chain/webs. c. Develop a model of a food web and predict the consequences of change on the proper functioning of the food web. d. Differentiate between the concepts of trophic levels and producers and consumers. 5. Describe how the availability of nutrients affects the productivity of ecosystems. 6. Apply the term niche to a local organism.
