2.5 Energy Flow in Ecosystems

What is the source of energy for photosynthesis?

• carbohydrates-chemical
• sunlight-radiant
• heat-thermal
• television-electrical

What are the reactants (what's needed) for photosynthesis?

• glucose and oxygen
• light, water, and carbon dioxide

What gas is released by plants during photosynthesis?

• sulfur
• carbon dioxide
• oxygen
• hydrogen

What is the purpose of photosynthesis?

• make glucose
• make ATP
• make light
• release carbon dioxide

What are the products (what's made) during photosynthesis?

• glucose and oxygen
• water, light, and carbon dioxide

What type of organism uses photosynthesis?

• plants
• bacteria
• animals
• both plants and bacteria

What is the energy conversion during photosynthesis?

• chemical --> chemical
• thermal --> electrical
• chemical --> electrical 
• radiant --> chemical

In which organelle (part of the cell) does photosynthesis take place?

• mitochondria
• chloroplast
• nucleus
• cell membrane

What is the gas we breath out that plants use for photosynthesis?

• sulfur
• carbon dioxide
• oxygen
• hydrogen

How can photosynthesis be related to cellular respiration?

• What's produced (made) by one is needed (the reactants) for the other
• They both produce the same products
• They both have the same reactants (need the same things)
• These 2 processes have nothing in common
