Photosynthesis
***WRONG = LOSE POINTS***
What is the purpose of photosynthesis?
To make food (glucose) for the plant using light energy.
What is the purpose of cellular respiration?
To release energy from food (glucose) for the cell to use.
***DOUBLE POINTS***
What is the difference between a producer and a consumer?
Producers create food for themselves and also provide energy for the rest of the ecosystem. Any green plant, like a tree or grass, as well as algae and bacteria, can be producers. Consumers are organisms that need to eat to obtain energy like deer and rabbits.
***WRONG = LOSE POINTS***
Match number with letter:
1. Weathering 2. Erosion 3. Deposition
A. Drop it B. Move it C. Break it
Weathering = Break it
Erosion = Move it
Deposition = Drop it
How many points is the study guide worth?
20 bonus points
***DOUBLE POINTS***
What are the reactants in photosynthesis?
Carbon dioxide (CO₂)
Water (H₂O)
Light energy (sunlight)
What are the reactants in cellular respiration?
Glucose (C₆H₁₂O₆) “sugar”
Oxygen (O₂)
2. Provide an example
Decomposers have the job of 'recycling' dead organisms and waste into non-living elements. Examples of decomposers include bacteria, fungi, worms, some insects, and snails.
Provide an example of physical weathering
Physical weathering breaks rock into smaller pieces without changing its chemical makeup.
Example: Ice wedging breaking apart a rock.
TRUE or FALSE:
Y axis = dependent variable
X axis = independent variable
TRUE
What are the products in photosynthesis?
Glucose (C₆H₁₂O₆) “sugar”
Oxygen (O₂)
What are the products of cellular respiration?
Carbon dioxide (CO₂)
Water (H₂O)
Energy (ATP)
Explain the difference between a food chain and food web?
A food chain follows one path of energy and materials between species. A food web is more complex and is a whole system of connected food chains.
***DOUBLE POINTS***
What are 3 examples of landforms caused by the effects of weathering, erosion, and deposition?
Canyons, deltas, sand dunes, u-shaped valleys, sandstone arches, sea arch, sea cliff

***DOUBLE POINTS***
What is responsible for a plant's green color?
Chlorophyll
***DOUBLE POINTS***
TRUE or FALSE:
Cellular respiration happens ONLY in animal cells.
FALSE:
Both plants AND animals use cellular respiration.
***DOUBLE POINTS***
Look at the following food chain:
grass → grasshopper → frog → snake.
Which are consumers?
Grasshopper, frog, snake
Provide an example of chemical weathering
Chemical weathering changes the chemical composition of the rock.
Example: Acid rain dissolving limestone.
***DOUBLE POINTS***
Where can you usually find the main idea in a passage?
Last sentence of introduction paragraph.
What is the cell called that absorbs light energy?
Chloroplast
***WRONG = LOSE POINTS***
What cell does cellular respiration take place in?
Mitochondria "POWERHOUSE OF THE CELL"
How did introducing wolves back into the Yellowstone ecosystem affect the other plants and animals? Use specific examples.
The herbivores started to avoid areas like valleys and gorges where they could be easily hunted by predators. As a result, those areas began to regenerate, and species such as birds, beavers, mice and bears returned. Plant life once again thrived along the riverbanks and erosion decreased significantly.
Explain how the grand canyon was formed.
The Grand Canyon was formed mainly by the Colorado River cutting through rock layers over millions of years. As the Colorado Plateau rose, the river's flow accelerated, deepening the canyon through erosion, while wind, rain, and ice further sculpted its walls into the breathtaking landscape we see today.
What experiment could you create to test which type of wheel makes a toy car fastest?
Set up a ramp at the same height and release the car from the same starting point each time. Change only the type of wheel, and use a stopwatch to measure how long the car takes to reach the bottom, repeating each trial three times for accuracy. Compare the average times for each wheel type to determine which one makes the car go fastest.
