ECO.LS2. Ecosystems: Interactions, Energy, and Dynamics ECO.LS2.1. Construct explanations for patterns relating to climate, flora, and fauna found in major terrestrial biomes (deserts, temperate grasslands, temperate forests, tropical grasslands, tropical forests, taiga, and tundra).
ECO.LS2.10. Plan and carry out an investigation measuring species diversity (richness and evenness) and density in a local ecosystem.
ECO.LS2.14. Obtain information regarding survivorship curves and reproductive strategies of various species. Choose one of these strategies and construct an argument regarding its effectiveness. Quiz, Flash Cards, Worksheet, Game Meiosis
ECO.LS2.16. Use a mathematical model to examine predator-prey interactions. Based on the model, construct an argument regarding the importance of predators in maintaining stability of prey populations.
ECO.LS2.17. Based on information obtained from research, construct explanations regarding mechanisms by which prey protect themselves from predation (including herbivory).
ECO.LS2.18. Use models to explain the impacts of types of symbiosis on the species involved in the relationship.
ECO.LS2.19. Carry out an investigation of stability and change within a local ecosystem. Identify signs of succession (primary or secondary). Based on investigation findings, make predictions regarding future changes in this ecosystem.
ECO.LS2.20. Plan and carry out an investigation examining kinesis and taxis in a simple organism. Construct and share explanations regarding observations.
ECO.LS2.21. Gather information regarding types of learned behaviors (fixed action patterns, imprinting, imitation, habituation, trial-and-error, associative learning – classical conditioning, operant conditioning). Ask questions regarding the importance of these beha
ECO.LS2.22. Construct an explanation for the relationship between sexual selection and sexual dimorphism.
ECO.LS2.23. Obtain and evaluate information regarding the relationship between altruistic behavior and kin selection.
ECO.LS2.3. Create a model of an ecosystem depicting the interrelationships among organisms with a variety of niches. Use the model to explain resource needs of these organisms.
ECO.LS2.4. Compare patterns of stratification and zonation in various terrestrial and aquatic ecosystems. Construct an argument regarding the importance of these patterns in ecosystem diversity.
ECO.LS2.5. Using the laws of conservation of energy, create a model of energy flow through the biosphere. Use the model to explain limitations in energy transfer and the need for ongoing energy input.
ECO.LS2.6. Compare pyramids of energy, numbers, and biomass to calculate rates of productivity within food chains and food webs among various biomes. Using mathematics, explain the relationship between biomass and trophic levels.
ECO.LS2.7. Use models to explain relationships among biogeochemical cycles (water, carbon, nitrogen, phosphorus).
ECO.LS2.8. Create a diagram tracing carbon through the processes of photosynthesis and respiration. Use the diagram to construct an explanation for the importance of photosynthesis and respiration in the carbon cycle.
ECO.LS2.9. Construct an argument from evidence regarding the importance of the microbial community in nutrient cycling.
