A simplified model of the carbon cycle in a forest is shown using two arrow styles:
  • Solid arrows (matter movement): CO2_2 in air → plant (photosynthesis) → animal (eats plant) → CO2_2 in air (respiration/decomposition).
  • Dashed arrows (energy flow): Sunlight → plant (captured in food). The model states: "Carbon atoms (matter) cycle; energy flows through and is not recycled in the same loop."
Which set of 2 statements is supported by the model?
