The formula for ​

Select answer

is ​ C₆H₁₂O₆ + O₂ --> CO₂ + H₂O + energy (ATP)

Multiple Choice

Photosynthesis is important because....

• plants need air to breathe
• it makes the plants green
• it is the process by which plants make their own food
• without it the Earth would all be a desert

Multiple Choice

Which of the following best describes photosynthesis?

• Photosynthesis converts radiant energy into chemical energy.
• Photosynthesis produces carbohydrates.
• Plants need sunlight, carbon dioxide, water, nutrients, and chlorophyll to complete photosynthesis.
• Plants use chlorophyll, water, and carbon dioxide to make sugar.

Multiple Choice

In order to make most of the ATP, both the Krebs Cycle and Electron Transport Chain occur in the ________________.

• Chloroplast

• Cytoplasm

• Mitochondria

• Nucleus

Multiple Choice

During CELLULAR RESPIRATION,

• Glucose is converted into cellulose

• Glucose is converted into sunlight

• Glucose is stored

Multiple Choice

Which of the following best describes the role of autotrophs in the flow of energy in an ecosystem?

• They produce their own food using sunlight and provide energy for other organisms.

• They consume only plants to obtain energy.

• They break down dead organisms to recycle nutrients.

• They store energy in the form of fat for long periods.

Open Ended

Why is the transfer of energy from the sun to plants and then to animals essential for life on Earth?

Multiple Choice

Which process in metabolism stores energy, and which releases energy?

Multiple Select

Which of the following are types of consumers in an ecosystem?

• Herbivores

• Carnivores

• Omnivores

• Producers

Multiple Choice

Why do energy pyramids have a limit to the number of levels?

• Because energy is lost as heat at each level

• Because there are not enough organisms

• Because energy is created at each level

• Because producers have unlimited energy

Multiple Choice

What is the equation for the process shown in the diagram?

• 6CO2 + 6H2O + Light → C6H12O6 + 6O2

• C6H12O6 + 6O2 → 6CO2 + 6H2O + Light

• 6CO2 + 6O2 + Light → C6H12O6 + 6H2O

• C6H12O6 + 6H2O → 6CO2 + 6O2 + Light
