photosynthesis
The sun has been up for several hours, and it has been shining on these trees. What can the trees do because they are in the sunlight? What does this mean for the number of energy storage molecules in the trees?
The trees can . . .
give off carbon to the air. Giving off carbon allows them to make energy storage molecules.
give off carbon to the air. Giving off carbon uses up energy storage molecules.
take in carbon from the air. The carbon is used to make energy storage molecules.
take in carbon from the air. The carbon is used to break down energy storage molecules.
Scientists are studying photosynthesis in a forest ecosystem that has plants, animals, and decomposers (which consume dead things). Which group or groups of organisms in the forest carry out photosynthesis?
all organisms in the forest
animals and decomposers
plants and decomposers
plants
This sea grass has had the sun shining on it for most of the day. What can the sea grass do because it is in sunlight? What does this mean for the number of energy storage molecules in the sea grass?
The sea grass can . . .
take in carbon from the air. The carbon is used to break down energy storage molecules.
take in carbon from the air. The carbon is used to make energy storage molecules.
give off carbon to the air. Giving off carbon allows the sea grass to make energy storage molecules.
give off carbon to the air. Giving off carbon uses up energy storage molecules.
Giant kelp are plantlike organisms that grow in clear ocean water. Over the last few hours some kelp has been taking in carbon from the water around it. Is the kelp in sunlight? What has happened to the number of energy storage molecules in the kelp?
The kelp . . .
is in sunlight, and the number of energy storage molecules in the kelp has decreased.
is in sunlight, and the number of energy storage molecules in the kelp has increased.
is not in sunlight, and the number of energy storage molecules in the kelp has decreased.
is not in sunlight, and the number of energy storage molecules in the kelp has increased.
An ivy plant has been taking in carbon from the air for several hours.
Is the ivy in sunlight? What has happened to the number of energy storage molecules in the ivy?
The ivy . . .
is in sunlight. The number of energy storage molecules in the ivy has decreased.
is in sunlight. The number of energy storage molecules in the ivy has increased.
