An owl eats a mouse. Which word describes this relationship?
What is an enzyme?
A protein that speeds up a chemical reaction.
What is the main purpose of photosynthesis?
To transform light energy into chemical energy (glucose/food).
What is the main purpose of cellular respiration?
To produce energy (ATP) from glucose.

Identify the organism(s) that can undergo both cellular respiration and photosynthesis.
Plants/Producers (Tree, Shrubs, Grasses)
The unfolding or unraveling of a protein shape.
Denature
Identify the organisms who can do photosynthesis
Plants, Algae and some bacteria (Producers/Autotrophs)
Identify the organisms who can do cellular respiration.
Plants and Animals (Producers and Consumers)

Create a food chain based on the information.
Algae --> Snails --> Catfish --> Herons

What is the optimal pH? How do we know?
Optimal pH is 4 because it has the highest enzyme activity.
What is the reactant and product for photosynthesis?
Water + Carbon Dioxide + Light --> Oxygen + Glucose
What is the reactant and produc for cellular respiration (aerobic)
Oxygen + glucose --> ATP + water + carbon dioxide

Using the graph, describe the pattern of population growth over time using your knowledge of biology.
Population increases rapidly due to abundant resources. Population reaches carrying capacity as resources become limited.

Identify the optimal temperature for the enzyme based on the data provided and justify your reasoning.
Optimal temperature 90 degree because it has the quickest/fastest reaction time
Explain how increasing light intensity will affect the rate of photosynthesis and justify your reasoning using your knowledge of biology.
Rate of photosynthesis will increase because photosynthesis needs light.
In a closed container, there is a aquatic plant was not exposed to light. Describe the change in amount of oxygen and carbon dioxide based on the scenario and justify your answer using your knowledge of biology.
Oxygen will decrease, carbon dioxide will increase because plant is undergoing cellular respiration. Cellular respiration uses oxygen and produces carbon dioxide.

The diagram above is an example of artic food web. Global warming has caused an increase in melting of the ice sheets. As a result, population of plankton and shrimp has decline. Describe the effect global warming has on the food web.
The food web will collapse because their less producers means less for the consumers and the organisms above the trophic level.
Describe two ways in which enzyme do their job.
1) lower activation energy
2) guide substrate to the right orientation
Two plant were placed under two different condition: one with light and one without light. One plant gain mass and the other plant lost mass. Which organisms is undergoing photosynthesis? Justify your answer using your knowledge of biology and include how mass will be affected.
Plant with light undergoes photosynthesis. It will gain mass because photosynthesis produces glucose which allows organisms to gain mass.
Two plant were placed under two different condition: one with light and one without light. One plant gain mass and the other plant lost mass. Which organisms is undergoing cellular respiration? Justify your answer using your knowledge of biology and include how mass will be affected.
Plant without light undergo cellular respiration The plant will lose mass because cellular respiration breaks down glucose to produce energy which is used up.
