Photosynthesis and cellular respiration can be seen as inverse of each other. Photosynthesis can be expressed with the following equation:

6 H 2 O + 6 CO 2 $$\rightarrow$$ C 6 H 12 O 6 + 6 O 2

CH 4 + 2 O 2 $$\rightarrow$$ CO 2 + 2 H 2 O

C 6 H 12 O 6 + 6 O 2 $$\rightarrow$$ 6 H 2 O + 6 CO 2

CO 2 + 2 H 2 O $$\rightarrow$$ CH 4 + 2 O 2

The products of photosynthesis are

Sunlight, water and carbon dioxide

The organelle responsible for photosynthesis is ___________ while the organelle responsible for cellular respiration is ____________.

Large central vacuole, mitochondria

A researcher is recording and monitoring data about a population of plankton-eating fish. When she analyzes the data, she notes a population change that starts at point D. Which is the best prediction to test in an investigation to explain why the population changed at point D?

People released an invasive species of fish into the ecosystem.

The number of predators in the area has decreased.

The fish entered into a mutualistic relationship with another organism.

Increased water clarity caused an increase in plankton density.

Water from nearby rivers or lakes is usually used to cool down the reactors in nuclear power plants. How would the release of this heated water back into the river or lake most likely affect the stability of the aquatic ecosystems?

It would cause a change in the biodiversity in the water.

It would change the number of mutations in plants growing near the water.

It would cause an increase in the sewage content in the water.

It would decrease the amount of sunlight necessary for photosynthesis in the water.

A student is investigating the population size of rabbits in a woodland ecosystem. She researches the known population of rabbits over 125 years and creates a graph representing the rabbit population with a solid line and the ecosystem's carrying capacity with a dotted line. Based on the information in the graph, what conclusion can the student draw about the time period between 1800 and 1835?

The rabbit population had few limiting factors and the ecosystem had not yet reached its carrying capacity.

The rabbit population had many limiting factors and the ecosystem had not yet reached its carrying capacity.

The rabbit population had few limiting factors and the ecosystem was beyond its carrying capacity.

The rabbit population had many limiting factors and the ecosystem was beyond its carrying capacity.

What would happen if the animals in the diagram were removed from the area?

Less fixed nitrogen would return to the soil.

No fixed nitrogen would return to the soil.

All fixed nitrogen would return to the soil.

More fixed nitrogen would return to the soil.

How would the carbon cycle be disrupted if many plants on Earth died off?

The amount of carbon dioxide in Earth's atmosphere would increase, trapping water vapor and causing Earth's atmosphere to become warmer.

The amount of water in Earth's atmosphere would decrease, trapping water vapor and causing Earth's atmosphere to become warmer.

The amount of oxygen in Earth's atmosphere would increase, releasing water vapor and causing Earth's atmosphere to become cooler.

The amount of nitrogen in Earth's atmosphere would increase, releasing water vapor and causing Earth's temperature to become cooler.

What statement BEST compares the biochemical processes of photosynthesis and cellular respiration?

Photosynthesis is the process of trapping the energy of the Sun and storing it in glucose. Cellular respiration is the process of releasing the energy stored in the chemical bonds of glucose.

Photosynthesis is the bacterial process of creating energy while cellular respiration is the eukaryotic process of releasing energy.

Photosynthesis is the plant process of releasing and utilizing energy while cellular respiration is the animal process of releasing and utilizing energy.

Photosynthesis is the process of trapping the energy of glucose. Cellular respiration is the process of releasing the energy stored in the bonds of the cell.
