Matter and Energy in Life


Photosynthesis - Matter Cycling and Energy Flow
Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.


Food and Chemical Reactions
Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.


Effects of Resource Availability
Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.


Matter Cycling and Energy Flow in Ecosystems
Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.


Ecosystem Interactions and Dynamics
Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
