C
The days are too short.
D
The weather is too warm.
16) Photosynthesis is important to humans because

B
It creates food for plants which in turn are food for animals
C
It gives off carbon dioxide
D
All of the above
17) Short-day plants planted along a busy city street never reproduce. Why might this be?

The city environment has too much pollution for the plants to be healthy enough to reproduce.
B
Nearly constant light from the sun, streetlights, shops, and passing cars never gives them a long enough night
C
There is not enough water because of too much concrete and not enough natural ground.
D
The people and vehicles that are around for most of the day an night give off heat never allowing it to get cold enough.
