Due to resource partitioning, zebra relative density changes over time and grass height.
<h3>What is resource partitioning?</h3>
- Resource partitioning is the process by which due to natural selection, competing species use different resources and niches.
- In the case of African savanna, right after peak rain all the three grazers (zebra, wildebeest, and Thomson’s gazelle) have high density.
- After rain in one month relative density of zebras is maximum but it becomes nearly zero after three months due to high density of wildebeest and then increases a little after six months.
- The density of zebras is greatest when the grass is tallest and most abundant because of resource partitioning as zebras get the most out of eating tall grass.
- Zebras can eat and digest faster taller grasses with many stems.
- This gives them an advantage over other grazers in terms of nutrition when the grass is tall.

Based on current data;
- The amount of carbon dioxide put into the atmosphere annually dueto human activities is 840 gigatons
- The amount of carbon in the atmosphere is 10 gigatons
- The amount of carbon stored in fossil fuels is 10,000 gigatons
<h3>What is the carbon cycle?</h3>
The carbon cycle a cycle showing how carbon is recycled between the atmosphere and earth.
The carbon cycle ensures that their is a balance of carbon in the atmosphere as well as on earth.
Human activities have increased the amount of carbon in the atmosphere.
The amount of carbon dioxide human activities put into the atmosphere annually in the present day is 840 gigatons.
The amount of carbon in the atmosphere is 10 gigatons
The amount of carbon stored in fossil fuels is 10,000 gigatons
Therefore, it can be concluded that human activities disrupt the carbon cycle.

Answer:
These results show that the body regulates its salt and water balance not only by releasing excess sodium in urine, but by actively retaining or releasing water in urine. The advantage of this mechanism is that the long-term maintenance of body fluids isn't as dependent on external water sources as once believed.
