● The population changes gathered from historical data or simulations of ecosystems at different scales and ● Data on numbers and types of organisms as well as boundaries, resources, and climate Identifying Relationships Students use tools, technologies, and/or models to analyze the data and identify and describe relationships in the datasets, including: ● Evidence to support the explanation and identify factors that have an effect on the carrying capacity of an ecosystem for a given population. Students analyze data to identify factors (including boundaries, resources, climate and competition) affect carrying capacity of an ecosystem and: ● Some factors have larger effects than do other factors ● That factors are interrelated ● The signifcance of a living or non living factor is dependent on the scale at which it occurs Interpreting Data Students use the analyzed data to: ● Identify the interdependence of factors (both living and nonliving) and resulting effect on carrying capacity and ● As evidence to support the explanation and identify the factors that have the largest effect on the carrying capacity of an ecosystem for a given population. Develop a quantitative model based on evidence to illustrate the cycling of matter and energy fow among organisms in an ecosystem. Components could include relative quantities related to organisms, matter, energy, and the food web in an ecosystem. Relationships Students identify the following relationships between components of the given model: ● Describe* the transfer of matter (as atoms and molecules) and fow of energy upward between organisms and their environment; ● Identify the transfer of energy and matter between trophic levels; and ● Identify the relative proportion of organisms at each trophic level by correctly identifying producers as the lowest trophic level having the greatest biomass and energy and consumers decreasing in numbers at higher trophic levels. Connections Students use the model to support the claims that include the idea that: ● Matter fows between organisms and their environment, ● Energy fows from one trophic level to another as well as through the environment, and ● Energy not transferred to higher trophic levels is instead used for growth, maintenance, or repair, and/or transferred to the environment, and the ineffciencies in transfer of matter and energy.
