What is the limiting factor in the following scenario? In a grassy African savanna, a large population of zebras lives and feeds on the tall grasses. During the rainy season, the grass grows quickly, and the zebra population thrives. However, one year, a severe drought hits the region. The rain doesn’t come for months, and the grass stops growing. As the food becomes scarce, some zebras begin to starve, and the population starts to decrease. Lions, which prey on zebras, are also affected. With fewer zebras around, the lions struggle to find enough food.

The number of lions
The amount of grass
The temperature of the air
The number of tree
