Which region would likely have the greatest amount of biodiversity? OA
B.
a mountainous region with two ecosystems, each of which supports a few different species
a grassland region with one ecosystem, which supports very large populations of a few different species
a coastal region with three ecosystems, each of which supports many different species
a cave region with one ecosystem, which supports small populations of many different species
D.

A grassland region with one ecosystem, which supports very large populations of a few different species

Explanation:

because the light is a great source of energy for the plants to survive. (i hope this )

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."
