Answer:
Carbon dioxide is added to the atmosphere by human activities. When hydrocarbon fuels ( wood, coal, natural gas, gasoline, and oil) are burned, carbon dioxide is released. During combustion or burning, carbon from fossil fuels combine with oxygen in the air to form carbon dioxide and water vapor.
These natural hydrocarbon fuels come from once-living organisms and are made from carbon and hydrogen, which release carbon dioxide and water when they burn.
Explanation:
So the answer is Fossil Fuels.
Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat.
Explanation:
When the organisms from one trophic level are consumed by organisms from the next level. ... A food chain can usually sustain no more than six energy transfers before all the energy is used up.
Both the sodium and the chlorine atoms need to obtain a stable electron configuration, thus, a complete outer shell of eight electrons.
Sodiums electron design is 2,8,1 and chlorines electron setup is 2,8,7. So all together for the two molecules of the two components to get a total external shell of eight electrons, sodium will give one electron to chlorine, and the chlorine particle will acknowledge the gave electron when responded with each other.
This outcomes in the sodium particle having an electron arrangement of 2,8 so is currently total. The chloride particle currently has an electron configuration of 2,8,8.
Since the molecules have moved toward becoming particles to end up stable, the Na+ and the Cl-particles draw in one another because of their contrary charges, which results in an ionic bond.
This is the reason sodium and chlorine cling to each other when responded.
When compared to each other, bird wings and butterfly wings can be described as ANALOGOUS STRUCTURES,
Analogous structures are those body structures in animals, which are used to perform similar functions but which have different evolutionary history. They are also called convergent structures. These structures are formed as a result of the need for the animals to adapt to similar environmental conditions. For instance, both bird and butterfly use their wings for flying.
