CHAPTER Ecosystems and Biomes the BIG idea Matter

CHAPTER Ecosystems and Biomes the BIG idea Matter and energy together support life within an environment. 1. 1 Ecosystems support life. 1. 2 Matter cycles through ecosystems. 1. 3 Energy flows through ecosystems. 1. 4 Biomes contain many ecosystems. CHAPTER OUTLINE NEW CHAPTER

1. 1 CHAPTER HOME KEY CONCEPT Ecosystems support life. Ecosystems are made up of living things (biotic) and nonliving things (abiotic). VOCABULARY ecology ecosystem Biotic biotic factor abiotic factor plants animals Abiotic temperature Sun soil water SECTION OUTLINE

1. 2 CHAPTER HOME KEY CONCEPT Matter cycles through ecosystems. Water, carbon, and nitrogen are materials that are necessary for life. They move through ecosystems in continuous cycles. VOCABULARY cycle water cycle carbon cycle nitrogen cycle Water Cycle Carbon Cycle Nitrogen Cycle click image to enlarge SECTION OUTLINE

1. 3 CHAPTER HOME KEY CONCEPT Energy flows through ecosystems. Producers are the basis of feeding relationships in ecosystems. VOCABULARY producer consumer decomposer cattails caterpillar Producer Primary Consumer food chain food web energy pyramid frog heron Secondary Consumer Tertiary consumer Food chains and food webs help show energy moves through living things. SECTION OUTLINE

1. 4 KEY CONCEPT CHAPTER HOME Biomes contain many ecosystems. Ecosystems of land biomes • are affected by climate • are affected by conditions of the soil • are characterized by types of plants VOCABULARY biome coniferous deciduous estuary Land Biomes click image to enlarge SECTION OUTLINE

1. 4 KEY CONCEPT CHAPTER HOME Biomes contain many ecosystems. Ecosystems of water biomes • can be freshwater or saltwater • are affected by landscape if freshwater • are affected by depth if marine VOCABULARY biome coniferous deciduous estuary Aquatic Biomes click image to enlarge SECTION OUTLINE
