Review for Quiz 2

What are the 3 things ALL PLANTS NEED.

• Soil, Water, and Oxygen
• Water, Love, and Sun light
• Sun light, Water, and Carbon Dioxide
• Water, Carbon Dioxide, and Glucose

Vocab question!! What is a producer

• an organism that needs to eat in order to get energy storage molecules (such as starch and fat)
• an organism that can make its own energy storage molecules (such as glucose)
• a molecule that organisms can use to release the energy they need to survive
• matter that makes up the living and dead organisms in an ecosystem

Scientists are studying photosynthesis in a desert ecosystem that has plants, animals, and decomposers (which consume dead things). Which group or groups of organisms in the desert carry out photosynthesis?

• plants
• plants and decomposers
• all organisms in the desert
• animals and decomposers

Vocab question!! What is a consumer?

• the process by which plants and other producers use energy from sunlight to change carbon dioxide and water into oxygen and glucose (an energy storage molecule)
• an organism that can make its own energy storage molecules (such as glucose)
• all the living and nonliving things interacting in a particular area
• an organism that needs to eat in order to get energy storage molecules (such as starch and fat)

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 seagrass?

• 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.

Vocab question!! What is carbon?

• a type of atom (a tiny piece) that makes up molecules such as carbon dioxide and energy storage molecules
• the process by which plants and other producers use energy from sunlight to change carbon dioxide and water into oxygen and glucose (an energy storage molecule)
• a molecule that organisms can use to release the energy they need to survive
• a molecule made of carbon and oxygen atoms

These images from the Sim show the same cell of a producer, but at two different times. What happened?

• It copied itself
• It became a chloroplast
• It went through photosynzthesis
• It went from biotic mater to abiotic matter

Vocab question!! What is carbon dioxide?

• a molecule that organisms can use to release the energy they need to survive
• all the living and nonliving things interacting in a particular area
• the process by which plants and other producers use energy from sunlight to change carbon dioxide and water into oxygen and glucose (an energy storage molecule)
• a molecule made of carbon and oxygen atoms

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.
• is not in sunlight. The number of energy storage molecules in the ivy has decreased.
• is not in sunlight. The number of energy storage molecules in the ivy has increased.
