<span>It's is the second one. The waste materials generated by one organism are often reused by other organisms.Mass, or matter, is conserved in all physical and chemical changes. Matter is not created or destroyed within ecosystems, it only undergoes physical or chemical changes. One example of this process is that the waste materials generated by one organism are often reused by other organisms as food or nutrients.</span>
<span>Geography and their environment are very influential on a region’s economic activity. For example, most major U.S. cities, including New York City, Chicago, and Boston, are all located near water. This is because when these cities were founded, water was the main mode of transportation. The environment also has many economic consequences, including the type of crops that can be grown and whether or not different activities can take place outdoors.</span>
Density (a) is the correct answer
<span>Scientists believe that differences in density cause hot, plastic-like rock in the asthenosphere to rise toward earth's surface. </span>
Explanation:
Using a maps scale most of the time involves some math. Usually you'd take a distance on the map (in inches) and multiply it to whatever that maps scale is, for example 1:500. A maps scale is used to show larger distances on a map in a ratio form to show the real ground distance. Showing 10 miles on a single piece of paper would be rather difficult if there weren't a scale
Answer:
Explanation:
Of the five oceans, the one with the greatest average depth is the Pacific, with about 4300 meters.
The reason is that this ocean is located on the great plate of the Pacific whose convergent margins are crossed by deep oceanic trenches under which this plate subducts.
In fact, the greatest ocean depth is also found in this ocean and corresponds to the Challenger Abyss, in the Mariana Trench, which reaches a depth of 11 km.
