The diagram is a model of an energy pyramid of an ecosystem. Primary producers are modeled by a wide rectangle labeled 100 percent. Above them are first-level consumers and a narrow rectangle labeled 10 percent. Then second level consumers at 1 percent, and on top the third-level consumers at 0.1 percent.

The levels of the diagram are labeled with percentages. What do the percentages represent?

A. the average energy requirement of organisms in each trophic level
B. the relative amounts of energy contained by the organisms in each trophic level
C. the energy lost as heat from one trophic level to the next
D. the rate of conversion of light energy to chemical energy

B

Explanation:

Amount of energy decreases as it goes higher up the trophic levels.

i would say the prokaryotic cells the prokaryotic cells are less complex, are usually found only in unicellular organisms and have more limited capabilities than eukaryotic cells.

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."
