Which of the following best describes the relationship between photosynthesis and cellular respiration?

Photosynthesis stores energy, while cellular respiration releases it

Both processes occur only in animals

Cellular respiration produces oxygen, photosynthesis uses it

Why are enzymes considered specific in their action?

Each enzyme only catalyzes one type of reaction due to its unique active site

They can work with any substrate

What is the balanced chemical equation for cellular respiration?

C 6 H 12 O 6 + 6O 2 --> 6CO 2 + 6H 2 O + Energy (ATP)

6CO 2 + 6H 2 O --> C 6 H 12 O 6 + 6O 2

C 6 H 12 O 6 + 6CO 2 --> 6O 2 + 6H 2 O + Energy (ATP)

6O 2 + 6H 2 O --> C 6 H 12 O 6 + Energy (ATP)

Explain how the carbon cycle helps maintain balance in Earth's atmosphere.

It cycles carbon between living organisms and the environment, preventing excess buildup of carbon dioxide

It removes all carbon dioxide from the air

A farmer notices that his crops are not growing well despite adequate sunlight and water. He adds a fertilizer rich in nitrogen. Explain how this might help the plants grow better.

Nitrogen is a key component of amino acids and proteins, which are essential for plant growth

Nitrogen helps plants absorb more sunlight

Nitrogen increases the temperature of the soil

Nitrogen makes the soil more acidic

A scientist wants to increase the rate of a reaction in a test tube. She adds more enzyme to the reaction. Predict and explain what will happen.

The reaction rate will increase because enzymes lower the activation energy needed for the reaction

The reaction rate will decrease because enzymes slow reactions

The reaction will stop completely

The enzyme will be used up and disappear

If a plant is placed in a sealed container with no light, what will happen to the levels of oxygen and carbon dioxide inside the container over time? Explain your reasoning.

Oxygen will decrease, carbon dioxide will increase, because only cellular respiration occurs without light

Oxygen will increase, carbon dioxide will decrease, because photosynthesis continues

Both gases will remain the same

Which of the following scenarios best illustrates the importance of the nitrogen cycle to living organisms?

Plants using nitrogen from the soil to build proteins necessary for growth

Animals breathing oxygen from the air

Which of the following is the correct equation for PHOTOSYNTHESIS?

6CO 2 + light + 6H 2 O --> 6O 2 + Glucose

6CO 2 + sugar + 6H 2 O -----> 6O 2 + light

6O 2+ light + 6H 2 O --> 6CO 2 + Sugar

6CO 2 + 6O 2 + 6H 2 O --> Light+ Sugar

The graph shows how enzymes affect reactions in cells. Which statement best summarizes the information shown in the graph?

Enzyme decrease the activation energy of the reaction.

Enzymes increase the energy of the reactants.

Enzymes decrease the energy level of the products.

Enzymes reverse the direction of the reaction.

What is the primary reason for the decrease in energy as it moves up the trophic levels in an ecological pyramid?

Energy is lost as heat at each trophic level

Energy is stored indefinitely at each level

Energy is destroyed as it moves up the pyramid

Energy is converted into matter

What is the primary difference between a food chain and a food web?

A food chain shows a single path of energy flow, while a food web shows multiple interconnected paths

A food chain includes only herbivores, while a food web includes only carnivores

A food chain is found only in aquatic environments, while a food web is found only in terrestrial environments

A food chain is a type of ecosystem, while a food web is not

In a food web, what role do decomposers play?

They break down dead organisms, returning nutrients to the soil

They are the top predators in the ecosystem

They compete with producers for sunlight

They produce energy for primary consumers

What is exponential growth in the context of population dynamics?

A rapid increase in population size when resources are unlimited

A constant increase in population size over time

A decrease in population size due to limited resources

A stable population size over time

How does carrying capacity affect population growth?

It limits population growth when resources become scarce

It has no effect on population growth

It allows for unlimited population growth

It causes population growth to become exponential

Which of the following is a major human impact on the environment?

Deforestation and habitat destruction

Stabilization of climate patterns
