Juan is studying fossils. his teacher wrote the following statements on the board and asked the students to put them in the correct order to describe how fossils are formed.

1. minerals seep into the organisms’s body and replace it with stone.
2. the organism completely decomposes, leaving behind an imprint.
3. an organism dies and its body is covered with a layer of sediment.
4. time passes, and sediment layers continue to build up on the organism.
which is the correct order of events for fossil formation?

a. 3, 2, 1, 4

b. 3, 4, 1, 2

c. 2, 3, 4, 1

d. 1, 3, 2, 4

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."    

but there is no

i guess you forgot putting it.
