The natural grassland ecosystem is known for its relatively high net primary productivity and high trophic efficiencies compare to other types of ecosystem, many reasons are responsible for this and three of them are listed below:
1. Natural grassland are regionally adapted to survive environmental fluctuations and grazing pressure.
2. The diverse producer base of the natural grassland ecosystem results in a large number of trophic connections. This enhances energy transfer and reduces energy losses.
3. Nutrient cycling in the natural grassland ecosystem is very efficient and this contributes to the overall efficiency of the ecosystem. The recyclers in the ecosystem decompose dead organic matters and release the energy trapped inside them.
About 25,000 light years from the center of the Milky Way Galaxy and about 25,000 light years from the edge. The Sun and the rest of the Solar System are close to the inner rim of the galaxy<span>'s Orion Arm, in the Local Fluff inside the Local Bubble, and in the Gould Belt.</span>

The correct answer = $48
Explanation:Let x represent the pre-sales' tax price of the dress.
Hence,
x + 0.06x = 50.88
Now solve for x,
x = </span>
x = 48
Hence the dress cost before sales tax = $48.

Answer:
True.
Explanation:
Cylindrical roller bearing assemblies requires lubrication to cushion the rollers and races while operating because the lubrication reduces friction of metals with each other. The two metals which slide over one another needs lubrication in order to reduce friction so it also increases the life of these metal parts so it is important for cylindrical roller to lubricate to work properly.
Mars is the planet that humans are most likely to colonize. Life on Mars will be different than life on Earth. Mars receives 66% less sunlight and a 62% weaker gravitational pull than Earth.
Mars is the fourth planet from the Sun, between Earth and Jupiter. Mars is about half the size of Earth and the planet is red-orange in color becuase of its rusty-red soil.
