LEARNING PROGRESSIONS

Bio 1.1 - ​ Plan and carry out an investigation to analyze and interpret data to determine how biotic and abiotic factors can affect the stability and change ​ of a population. ​ Emphasize stability and change in populations’ carrying capacities and an ecosystem’s biodiversity. (LS2.A, LS2.C)

● I understand why we study organisms and their environment. ● I understand how abiotic and biotic factors shape an ecosystem and

determine communities that will be successful in it.

Bio 1.2 - Develop and use a model ​ to explain cycling of ​ matter ​ and flow of ​ energy ​ among organisms in an ecosystem. ​ ​ Emphasize the movement of matter and energy through the different living organisms in an ecosystem. ​ Examples of models could include food chains, food webs, energy pyramids or pyramids of biomass. (LS2.B) Bio 1.3 ​ ​ Analyze and interpret data ​ to determine the effects of photosynthesis and cellular respiration on the ​ scale and proportion of carbon reservoirs in the carbon cycle. ​ Emphasize the cycling of carbon through the biosphere, atmosphere, hydrosphere, and geosphere and how changes to various reservoirs impact ecosystems. Examples of changes to the scale and proportion of reservoirs could include deforestation, fossil fuel combustion, or ocean uptake of carbon dioxide. (PS3.D, LS1.C, LS2.B) Bio 2.1 - Construct an explanation ​ based on evidence that all organisms are primarily composed of carbon, hydrogen, oxygen, and nitrogen, and that the ​ matter ​ taken into an organism is broken down and recombined to make macromolecules necessary for life functions. ​ Emphasize that molecules are often transformed through

● I understand the levels of organization in ecology. ● I understand what symbiosis is and why it is important in nature. ● I understand how matter flows through an ecosystem. ● I understand how energy flows through an ecosystem. ● I understand how matter flows through an ecosystem. ● I understand how energy flows through an ecosystem.
