Standard 2: Students will understand that the features of Earth’s evolving environment affect living systems, and that life on Earth is unique in the solar system.

Objective 2: Analyze how ecosystems differ from each other due to abiotic and biotic factors.
a. Observe and list abiotic factors (e.g., temperature, water, nutrients, sunlight, pH, topography) in specific ecosystems.
b. Observe and list biotic factors (e.g., plants, animals, organic matter) that affect a specific ecosystem (e.g., wetlands, deserts, aquatic).
c. Predict how an ecosystem will change as a result of major changes in an abiotic and/or biotic factor.
e. Analyze interactions within an ecosystem (e.g., water temperature and fish species, weathering and water pH).
