Question

wildebeest and buffalo. by 1900, the wildebeest population in the
serengeti dropped from over a million to only about 200,000.
things began to change in the late 1950s when scientists made a
vaccine for rinderpest. the kenyan government gave the vaccine
to cattle, which stopped the disease from spreading to wild
animals. by 1963, rinderpest was mostly gone, and the wildebeest
population started to recover.
over the next 10 years, the number of wildebeest grew from
200,000 to over a million. but after about 1975, the population
stopped growing and stayed at about 1.2 million animals. scientists
then asked: why did the population stop growing?

1. what do wildebeest eat in the serengeti?

grass

1. why do wildebeest migrate?

1. what happened to wildebeest when rinderpest arrived?

rinderpest

1. how did the vaccine change the wildebeest population?

it stopped the disease from
spreading to wild

1959 to 2001

Explanation:

1.

Wildebeest are herbivores, and in the Serengeti, their primary food source is grass.

Wildebeest migrate to follow seasonal food sources (grass growth) and access water, as well as to avoid harsh environmental conditions like droughts.

When rinderpest arrived, the wildebeest population in the Serengeti dropped from over a million to about 200,000 (as stated in the text).
