a. Plants absorb water through their roots. The water then moves up into the stem and
leaves of a plant
b. Plant have structures that capture light energy from the sun
c. Plants get carbon dioxide from the air
d. Using light energy, plants then change carbon dioxide and water into sugar and
oxygen
Write one letter in each box to label each part of the ocean food chain shown here.
