Asystem in which both energy and matter are exchanged with the surroundings is known as a(n)
a. dynamic system
b. open system
c. closed system
d. flowing system

The correct answer is option b.

Explanation:

Dynamic system is a system in which motion and other interactive forces involved.In this system mathematical functions are used to expresses the time dependence of the point in a space.

Open system is a system in which exchange of mass and energy is allowed. In this  mass and energy of the system interacts with the surroundings.

Closed system is a system in which exchange of mass and energy is not allowed. In this  mass and energy of the system do not interacts with the surroundings.

Flowing system is a system with continuous flow of energy and (or) mass from one temporary state to another temporary state.

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]

the answer is: reproductively

i think i spelled it wrong lol

anyways hope i
