Energy Flow

Susan has just moved into a new house. For some reason, she cannot get the grass to grow in her yard. She decides to grow small amounts of grass inside her house as part of an experiment. The first group of grass is exposed to a light intensity of 400. The second group is exposed to a light intensity of 1200.

• The plants at a light intensity of 400 will grow more quickly than the plants at 1200.

• The

  plants at a light intensity of 400 will produce more glucose than the plants

  at 1200.

• The plants at a light intensity of 1200 will perform only stage 1 of photosynthesis.

• The plants at a light intensity of 1200 will produce more oxygen than the plants at 400.
