Some plants can live in deeper parts of the ocean where less sunlight is able to reach. Sunlight contains a mixture of all light colors—red, orange, yellow, green, blue, indigo, and violet. These colors of light are important for plants to perform photosynthesis. Red, orange, and yellow light are unable to reach deep in the water.
Deep ocean plants absorb blue and green light colors to perform photosynthesis.
Ocean animals breathe out carbon dioxide that deep ocean plants use to perform photosynthesis.
Deep ocean plants move to the surface during the day to capture light and perform photosynthesis.
Ocean animals move around and carry nutrients to the ocean bottom for plants to perform photosynthesis
Select the outputs of photosynthesis.
carbon dioxide
oxygen
water
sunlight
glucose
Which process is the least harmful way to remove oil from the water?
Leave the oil alone so it can spread out naturally.
Use floating devices to enclose and collect the oil.
Light the oil on fire so it burns off the water rapidly.
Add chemicals to the water to break down the oil.
