certain kinds of shells are always found in rock layers with plants fossils. Dinosaur fossils show up only in layers above or with plant fossils. What does this tell you about when these orangisms lived?

i am positive it is c. condensing but i may be wrong

"d.) carbon dioxide and hydrogen sulfide"

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
