Which of the following statements best describes the relationship between carrying capacity and population size?
A. Population size increases the carrying capacity.
B. Population size is not affected by carrying capacity.
C. Carrying capacity increases population size.
D. Carrying capacity determines the maximum population size.

D. Carrying capacity determines the maximum population size.

Explanation:

Carrying capacity is number of individual an environment can sustain without depleting, exhausting the available resources.

The carrying capacity of a given area is the population an area can sustain with the available resources such as food,shelter,natural resources,water without exhausting the resources for continued use. For animals it is the amount of grass an animal can graze on without compete depletion. When a population is beyond the carrying capacity there is competition and depletion of available resources. Emigration can occur when the population rises beyond the carrying capacity. Increase birthrate and reduction in death rate increases population in a given environment.

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."
