Step 1)Carbon enters the atmosphere as carbon dioxide from respiration(breathing)and combustion (burning)
Step 2)Carbon dioxide is absorbed by plants to make carbs in photosynthesis. These producers then put off oxygen.
Step 3)Animals feed on the plants. Which passes carbon along the food chain.Most of the carbon these animals consume however is exhaled as carbon dioxide. This through the process of respiration. Then the animals and plants eventually die.
Step 4)The dead plant and animal are then eaten by decomposers in the ground. The carbon that was in there body is then returned to the atmosphere as carbon dioxide.In some circumstances th process of decomposition is prevented. The decompose animals and plants may then be available as fossil fuel in the future for combustion
B because if it is semipermable it means that the salt would be stuck on one side while the water could move freely and get water to the cell
The formation of limestone takes place in shallow warm marine waters. Limestone forms from the collection of waste like shells, fecal matter, coral, and algal—so tropical marine animals. Since limestone is a sedimentary rock formed from tropical marine animal's leftovers, limestone deposits can tell scientists that the environment in which they evolved from was a tropical one.
Natural selection, in which the fittest organisms are the most capable to survive and reproduce.
