The ratio of starlight to sunlight is much, much smaller than 0.5%. A value of 0.0000001% is far more accurate.
<span>Subsistence farming involves farmers growing just enough food that will be adequate for them and their families. So no surplus is farmed for sale. The Green Revolution allowed larger crop yield for farmers by introducing resistance strains, fertilizers and pesticides. As you can imagine, the wide spread use caused a very negative impact on the environment. Subsistence farming was basically revamped by the Green Revolution to allow surplus be produced for sale in developing nations.</span>
A grid system make it easier to find A LOCATION on a map.
The grid references define locations on maps by using Cartesian coordinates. The grid lines used on maps define the coordinate system and they are usually numbered to provide unique references to features.
<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>
False. Contour lines indicate different levels of elevation. One line might indicate an elevation of 100 feet, and the line next to it an elevation of 200 feet, and so on. When those lines are close together it means that the elevation is rising very quickly from 100 feet to 200 feet, which means a steeper slope. When those lines are farther apart, it means that there's a lot more space between the 100-foot elevation and the 200-foot elevation, which means a more gentle slope.
