What type of population monitoring method will be best for monitoring the species listed? is an appropriate method to monitor a population of swallows, while is an appropriate method to monitor a population of tortoises.

Point counts and line-transect  distance sampling methods are appropriate method to monitor a population of swallows and tortoises respectively.

Explanation:

Monitoring a population involves using field techniques methods for selection, to count, capture, observe, measure, mark individuals selected from the targeted population so that one can collect data that are needed to achieve study objectives at hand.

Point counts as a field techniques are commonly used to count or keep track of the fowls of the air (birds). Observation are made over a certain standardized period of time and record of the amounts birds from a single point is the routine.

While the field techniques known as line-transect distance sampling methods comes in handy for monitoring the tortoise population.

It shows how some individuals in a population go missing and allows for a concurrent working out of a method for controlling, tracking, marking measuring those number of individuals that is going missing.

"-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."
