Which best explains why lithium should be extracted from recycled lithium-ion batteries?
1. lithium is found in pure form in nature.
2. lithium is inexpensive to recycle.
3. lithium is a limited resource.
4. lithium is very expensive to recycle.

Lithium is a very rare element that is found in nature in compound forms. These compounds are found in nature are hard to separate. Thus the lithium are very essential to recycle from used batteries.

Option C

Lithium is an element that is an alkali metal sitting in top of sodium in the 1st group of periodic table. Its a very strongly reactive element which reacts vigorously with each and every possible non metal to produce compounds. Also the availability of lithium on Earth's crust is very less.

And it's a very useful element used to produce different batteries, electronic circuits etc. So the price of this metal is very high. Thus recycling of lithium from the batteries are very essential to get a constant source of lithium for newer products.

the correct answer would be 6 feet.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
