LS2.C: Ecosystem Dynamics, Functioning, and Resilience
-
SWBAT list factors that can impact an ecosystem, both naturally occurring and those influenced by anthropological effects.
-
HS-LS2-2.Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales
- Decline of one species can affect entire ecosystem
-
HS-LS2-7. Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.
- Human activity has an impact on ecosystems
-
LS2.A: Interdependent Relationships in Ecosystems
-
SWBAT analyze and graph a predator- prey relationship in their ecosystem
-
HS-LS2-1.Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.
- Analyzing data, population predictions can be made.
- As prey decrease predators decrease.
- As predators decrease prey increases.
-
SWBAT describe the different cycle of a nutrient (carbon & water) as it moves through an ecosystem.
-
HS-LS2-5.Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.
- Photosynthesis uses carbon.
- Cellular respiration releases carbon
-
HS-LS2-4.Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.
- Carbon and water cycles through the ecosystem
-
HS-LS2-3.Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.
- Decomposers break down dead organisms
-
LS2.B: Cycles of Matter and Energy Transfer in Ecosystems
-
SWBAT describe how energy flows through ecosystems (autotrophs and heterotrophs) and provide specific description of how energy flows through your ecosystem
- Energy is passed from prey to predator.
- Energy decreases as you move up the trophic levels.
- Energy is given off by the sun.
- Sun is the ultimate source of energy
