Open on a Jamboard After you have completed your graph, answer the following questions.
1. a. Seawater is actually about 96.5 percent water. If you were going to construct a graph to illustrate
the composition of seawater, how many degrees on the graph would be needed to represent water?
b. On such a graph, how many degrees would be needed to represent the total of all of the dissolved
salts contained in seawater?
2. If erosion continues to carry more and more dissolved salts into the oceans, after many thousands of
years, how would you expect the composition of seawater to be different from how is it today?
3. Many animals that live in the ocean use some types of dissolved salts to build their shells. What would
happen to the composition of seawater if these animals were to decrease drastically in number?

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
