Which type of population growth is shown in this graph? population of bacteria
exponential
linear
logistic
limited

Bacterial population shown in the graph is of Exponential type.

Explanation:

When the rate of population increases over time in proportion to the population size,  it is known as exponential growth of population. Bacterial reproduction happens in an hour time span for many bacterial species by splitting itself in half.

This shows how the exponential growth occurs in bacteria. The amount of population gets increased with added organisms in generations of species.

"-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."    

not only is it colder, it also becomes darker, less salty, and more dense.
