=Unit Title: Aquatic Ecosystems and Their Interactions= Grade level: 10 Subject Area: Accelerated Biology Unit Designer: Cinda Murray Time frame: 2 weeks =Pennsylvania Environment & Ecology Standard:= 4.6.10A Explain the biotic and abiotic components of an ecosystem and their interactions. 4.6.10B Explain how cycles affect the balance in an ecosystem. 4.6.10C Analyze how ecosystems change over time.

=Performance Indicators / Objectives:= • Students will compare the interactions of biotic and abiotic components in an ecosystem. • Students will analyze the effects of abiotic factors on specific ecosystems. • Students will describe how the availability of a resource affects organisms in the ecosystem. • Students will explain energy flow in a food chain through an energy pyramid. • Students will explain trophic levels. • Student will evaluate the efficiency of energy flow in a food chain. • Students will explain how erosion and sedimentation have changed the quality of soil related habitats. • Students will explain the concept of carrying capacity in an ecosystem. • Students will interpret possible causes of population fluctuations. • Students will examine and explain how organisms modify their environments to sustain their needs. • Students will identify a specific environmental impact and predict how what change may take place to affect homeostasis. • Students will identify the major biomes and explain their similarities and differences. • Students will assess the effects of latitude and altitude on biomes. • Students will describe an element cycle and its role in the ecosystem. • Students will explain the consequences of interrupting natural cycles. • Students will identify causes of succession. • Students will identify and explain the succession stages in an ecosystem. • Students will analyze the consequences of interrupting natural cycles.
