Photosynthesis and Respiration
1. Photosynthesis
Use the word bank below to fill in the blanks
food
plants (producers)
_______________ perform photosynthesis to create _________, in the form of sugar, for themselves. In the process of photosynthesis plants use sunlight
carbon dioxide
__________________ from the atmosphere, water, and ___________ to create these sugars. Producers also make water and oxygen through photosynthesis
___________________.
Use the description above to help you arrange the words you have to show the chemical formula for photosynthesis.
sunlight
carbon dioxide
(what plants are using)
water
sugar

2. Respiration
Use the word bank below to fill in the blanks
plants (producers)
animals (consumers)
____________ and _____________ perform respiration to create energy
_________ for themselves. In the process of respiration organisms use sugars
oxygen
___________ from the atmosphere to release energy from __________. Producers use the sugars they create during photosynthesis for eating
respiration. Consumers use sugars from ___________ other organisms for respiration. Along with energy, respiration also makes carbon dioxide and water.
Use the description above to help you arrange the words you have to show the chemical formula for respiration.
oxygen
sugar
carbon dioxide
(what organisms are using)
water
(what organisms are creating)
sunlight
Look at the chemical formula for photosynthesis and the chemical formula for respiration. What do you notice about the two formulas?
Summary
­ Only ___________ perform photosynthesis
­ Both ___________ and ___________ perform respiration
­ The chemical formula for photosynthesis is:
­ The chemical formula for respiration is:
­ The chemical formulas for photosynthesis and respiration are ___________________.
