Seagrass is a plant that grows on the ocean floor. It grows in shallow parts of the ocean. These producers have the ability to grow and survive in aquatic ecosystems.

Which of the following statements is not true about aquatic plants?

• Aquatic plants take in carbon dioxide from the water.

• Aquatic plants get light energy from the sun.

• The leaves in aquatic plants take in light to start the process of photosynthesis.

• Aquatic plants cannot undergo the process of photosynthesis because they are underwater.

A student conducts an experiment to see how bean plants grow. She uses a jar, a paper towel to hold the seeds, and water. She places the jar in a sunny window and observes the plant as it starts to grow. The image below shows the setup.

The student places the same number of bean seeds in two identical jars. She wants to determine if bean plants need water to grow. What will best help her determine if plants need water to grow?

• Both jars have no water

• Both jars have 1 cup of water.

• One jar has no water and the other jar has 1 cup of water.

• One jar has 1 cup of water and the other jar has 2 cups of water.

A classroom aquarium has producers, consumers, and decomposers. The aquarium represents a pond ecosystem. The drawing below shows the aquarium.

A student observes that when a bright light shines on the aquarium, tiny bubbles form on the plants. No bubbles form on the plants in the dark. Which of the following best explains the student's observation?

• The gas bubbles are the energy that plants produce from the bright light.

• Bright light makes heat. This causes the water around the plant to boil.

• Gas bubbles are pulled down from the water surface by the plant to make food.

• The plants use light to make food. The bubbles on the plants are produced during this process.

The photo shows a Giant Tillandsia plant growing on a tree branch. A Giant Tillandsia uses its roots to attach to the branch. These plants are classified as air plants. Air plants absorb what they need to grow and survive from the air and do not need soil.

What do air plants absorb from the air to survive and grow?

• nutrients and carbon dioxide

• sunlight and oxygen

• sugars and oxygen

• water and sugars

Which evidence supports the location of where photosynthesis occurs in the plant?

• The plant's flower attracts insects such as bees.

• The plant's leaves create sugars for the plant.

• The plant's roots absorb water from the ground.

• The plant's stem transports water to the rest of the plant.
