Need ! an energy pyramid is shown below. within ecosystems, energy generally flows from a. primary consumers to producers. b. secondary consumers to primary consumers. c. primary consumers to secondary consumers. d. all of these

C.  primary consumers to secondary consumers.

Explanation:

An eco-system is a set of living and non living organisms living in a certain area where they interact with each other to fulfill their life requirements. One of the every important component of any eco-system is food chain.

What is food chain?

So based on above information we can say that flow of energy in an eco system is as:

Therefore, only option C is correct.

Hope it help!

1.the evidene of the reaction

2.yes

3.yes

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."
