Question 1 You are encouraged to conduct research for the questions below:
Provide evidence that water crisis in South Africa involves interrelated systems and is a long-
term problem; and not simply a one-dimensional (it did not rain enough!) temporary
phenomenon (which nature will soon solve!). You can name and discuss in your own words)
five major factors (natural as well as human), how they may contribute over time to South
African water crisis. State the effect it has on humans, animals and the environment. Suggest
solutions that can be done by households and or government.

Question 2
As part of water conservation

doctors i believe if i'm wrong sorry

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.

yes, because even though a theory has a  lot of evidence to support it, it is not always true
