How does bioenergy with carbon capture and storage (BECCS) differ from our common practice of burning fossil fuels to generate electricity and power internal combustion engines (e.g., cars and trucks)? Choose all applicable.

	BECCS stores carbon in a reservoir (pool) other than the atmosphere, while the carbon emitted in the burning of fossil fuels is usually emitted into the atmospheric reservoir.
	In BECCS, the carbon emissions are captured and stored, while the carbon emissions from burning fossil fuels are not usually captured and stored.
	BECCS does not produce carbon dioxide as part of the process of generating electricity, while burning fossil fuels does produce carbon dioxide as part of the process of generating electricity.
	BECCS uses the primary productivity from recent times, while burning fossil fuels uses the primary productivity from millions of years ago
	BECCS uses the chemical potential energy generated during photosynthesis, while the common burning of fossil fuels does not use chemical potential energy generated during photosynthesis.

1. Refer to Figure 9.13. Which photo(s) (AâI) best illustrate(s) the methods of fossilization or fossil evidence listed
below? (Photos/letters may be used more than once.)
Petrification: The small internal cavities and pores of an original organism that are filled with precipitated mineral
matter. Photo(s):
Cast: The space once occupied by a dissolved shell or other structure is subsequently filled with mineral matter.
Photo(s):
Carbonization: Preservation that occurs when fine sediment encases delicate plant or animal forms and leaves a
residue of carbon. Photo(s):
impression: A replica of an organism, such as a leaf, left in fine-grained sedimentary rock. Photo(s):
Amber: Hardened resin of ancient trees that preserved delicate organisms such as insects. Photo(s):
indirect evidence: Traces of prehistoric life but not the organism itself. Photo(s):
