Which statement regarding the decreased level of stratospheric ozone is correct?

• Increased photosynthetic activity has been measured in the phytoplankton around Antarctica

• The largest decrease in the level of stratospheric ozone over the Arctic region occurs between January and April

• Although the Montreal Protocol led to a reduction in the use of CFCs, it will have little effect on stratospheric ozone levels in the long term

• There is no correlation between the incidence of cataracts and skin cancers and the lower level so stratospheric ozone

• The global crop yields of wheat, rice, and corn have increased since the reduction in CFC use

• UV-A

• UV-B

• UV-C

• manure and/or trash

• petroleum

Which type of fuel produces the most sulfur?

• wind

• coal

• biomass

• nuclear fission

How does biomass reduce our carbon footprint by producing less CO2 than fossil fuels?

• Plants absorb the same amount of CO2 that is released when it is burned.

• Plants remove CO2 from the atmosphere and put it permanently into the ground.

• Biomass filters CO2 to make it more environmentally stable.

• Biomass doesn't release any CO2 when burned.
