True?
false?
reasoning
statement
cellular respiration cannot occur
without glucose.
whereas animals produce carbon
dioxide, plants produce oxygen at the
end of respiration.
inhaling oxygen and exhaling carbon
dioxide is called respiration.
and the reasoning

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

looks like the answer is     c     to me!
