Which is the ONLY cycle that does not require chemical changes?

Water cycle. Only physical changes.

100

Which trophic level has the most biomass?

The producers

100

Sort these substances into organic or inorganic categories: Sodium Chloride, Water, CH4, Amino Acids

Organic: Amino Acids, CH4

Inorganic: Sodium Chloride, Water

100

What are the inputs of photosynthesis

Carbon dioxide and water

100

What are the inputs of cellular respiration?

Oxygen and glucose

200

Transpiration is part of which cycle? How does transpiration occur?

Water cycle. Water leaves the leaves of plants through the stoma.

200

Which biological process do plant use to take in carbon dioxide from the atmosphere and get energy? 

Photosynthesis.
200

Where is the chemical energy in a molecule or compound contained?

Bonds

200

What are the outputs of photosynthesis?

Oxygen and glucose

200

What is the goal of cellular respiration? Which molecule is being made?

ATP (adenosine triphosphate)

300
How does planting legumes in a field the year before a crop harvest affect the productivity of the field?

Legumes put nitrogen back into the soil. This makes the field more fertile for the crops the following year.

300

What are the three types of organisms that exist in an ecosystem?

Producers, consumers, decomposers.

300

What causes fire or an explosion during a chemical reaction?

Fire or explosions are the manifestation of energy. It is the result of energy being given off but it is not energy in itself. 

300

Can plants undergo photosynthesis in which organelle?

Chloroplast

300

How is ATP used to produce energy?

ATP gets a phosphate group chopped off and that releases energy for the cell. 

400

What is nitrogen used for in the body? What is the source of nitrogen that we use?

Nitrogen is in amino acids and nucleic acids. This ultimately comes from nitrogen in the atmosphere that has been fixed by plants. 
400

When going from one trophic level to the next, how much energy is transferred? What does this mean for the organisms at the highest trophic level?

5-20%. This means there will be far less energy available to the highest consumer at the top of the pyramid.

400

Is carbon dioxide (CO2) an organic molecule?

No

400
Within the chloroplast, what structure do the light reactions take place in?

Thylakoids

400

What are the components of ATP?

Adenine + Ribose sugar + 3 phosphates

500

Humans have contributed to the carbon cycle by _____________________. What impact does this have on the global community?

Burning fossil fuels. This results in more greenhouse gases in the atmosphere and contributes to climate change. 

500
Why is the population of the apex predator much lower than the population of the producers?
Since less energy is available to the apex predators than the producers, there has to be fewer of them.
500

What is required for a compound to be considered organic?

High energy bonds of CH and CC

500

What does the prefix phyto- mean? For example, phytobacteria.

Do you think these bacteria would be producers, consumers, or decomposers?

Photosynthetic. These would likely be producers

500

The first part of cellular respiration is called Glycolysis and it occurs in the ________. The rest of cellular respiration occurs in the _________. 

Cytoplasm. Mitochondria.
