Grace wants to find out how many kinds of organisms live in tides pools on a certain rocky shore. which of the following would be the best investigation for grace conduct?
a. survey
b. field study
c. experiment
d. laboratory study

B, Field study. This is because she wants to find a number in a certain location that cannot be replicated. She needs to observe the amount of species so an Experiment does not work. A survey is a questionnaire and wouldn't help because she needs to see it herself. A lab study wouldn't replicate the rocky shores she needs to investigate.

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."    

do yall know the answer?
