Unit 2 Objectives:
Standard
Standard 3, Benchmark 1: Matter tends to be cycled within an ecosystem, while energy is transformed and eventually exits an ecosystem
Standard 3, Benchmark 2: The size and persistence of populations depend on their interactions with each other and on the abiotic factors in an ecosystem
Evidence Outcomes of Mastery
- Understand the levels of organization in the biosphere
- Analyze how energy flows through trophic levels
- Define and distinguish between matter and energy and explain how ecosystems follow the laws of conservation of matter and energy
- Describe how energy flows from producers to consumers
- Describe how matter (i.e. carbon, nitrogen, phosphorus, and water) cycles through an ecosystem
- Analyze situations where human involvement (addition of fertilizer, clear cutting, etc.) affect an ecosystem
- Determine the impact of removing species from or introducing non-native species to ecosystems
- Evaluate communities in terms of primary and secondary succession as they progress over time
- Know what factors contribute to climate and the role of climate in creating different biomes
- Determine factors that can limit growth of a population
- Distinguish between logistic and exponential growth and what leads to changes in growth for a population
- Evaluate assumptions about the trends in human population growth and the projected consequences
