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.

Answer:
The correct answer is option - C. low power objective.
Explanation:
In microscopes, low power objectives have a wide field of view and use to study the many smaller specimens or large specimens. 10X is the power of the low objective.
To study the depth of the field the lower objective rotated and aligned on the place over the specimen. When you move to high power objective the field of view gets close in and only can study the smaller specimen or small section of a large specimen.
Thus, the correct answer is option - C. low power objectives.
Answer:
This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.
