Photosynthesis
This gas is an input of photosynthesis.
What is carbon dioxide?
This gas is released as a product of cellular respiration.
What is carbon dioxide?
An organism that makes its own food.
What is an autotroph?
This type of reaction releases energy.
What is an exergonic reaction?
Name two Earth spheres involved in photosynthesis.
What are the biosphere and the atmosphere?
This is where photosynthesis takes place in a plant cell.
What is the chloroplast?
This is where cellular respiration occurs in the cell.
What is the mitochondria?
An organism that eats other organisms for food.
What is a heterotroph?
This type of reaction absorbs energy.
What is an endergonic reaction?
Predict what would happen to the amount of carbon dioxide in the atmosphere if all plants on Earth died.
The amount of carbon dioxide in the atmosphere would increase. Plants use carbon dioxide for photosynthesis, so without plants the carbon dioxide would remain in the atmosphere.
This is the name of the green pigment that absorbs light energy.
What is chlorophyll?
This is the name of the high energy molecule produced during cellular respiration.
What is ATP?
This process releases energy by breaking down glucose.
What is cellular respiration?
The breaking down of large molecules into smaller ones.
What is catabolism?
Explain how deforestation could negatively impact the cycling of carbon between the Earth's spheres.
When trees are cut down and not replanted, there are fewer plants to take in carbon dioxide from the atmosphere. Decomposition and burning of trees also releases carbon dioxide into the atmosphere.
Two products of photosynthesis.
What are glucose and oxygen?
Explain the relationship between a snail and elodea using your understanding of photosynthesis and cellular respiration.
Elodea uses the products of cellular respiration (carbon dioxide and water) as reactants for photosynthesis, which creates glucose and oxygen. The snail uses these products as reactants for cellular respiration.
This organism breaks down dead things in an ecosystem.
What is a detritivore?
The building of larger molecules from smaller ones.
What is anabolism?
This process uses chemicals instead of sunlight to produce energy.
What is chemosynthesis?
Using the chemical equations, explain how photosynthesis and cellular respiration demonstrate the law of conservation of matter.
The reactants of photosynthesis are the products of cellular respiration, and vice versa. The atoms are rearranged during each process, but no matter is lost or destroyed.
This molecule is the primary source of energy during hibernation.
What is glucose?
Give an example of an autotroph and a heterotroph.
The blueberry bush is an example of an autotroph. The snake is an example of a heterotroph. (answers can vary)
When chemical bonds are broken, energy is _____.
What is released?
Explain how the snail elodea model demonstrates interactions between the Earth's spheres.
The snail (biosphere) releases carbon dioxide into the water (hydrosphere). The elodea (biosphere) uses the carbon dioxide from the water and light energy from the sun (atmosphere) to produce glucose.
