observations of different species with varying traits

Finches on different islands had different types of beaks.

Explanation:

Charles Darwin, on his voyage, visited the Galápagos islands, and observed the finches (among other species, of course). He saw that in every island, the birds were adapted to the particular environment. For example, finches that eats small insects has sharp and thin beaks, differently from finch species that usually feed from large seeds, which posseses large and tough beaks. Also some of them had different beaks to feed from cactus fruit or pulp.

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."
