Answer 2

are改成is
the number of 是……的数量意思,野生动物的数量，数量做主语，谓语动词用单数
这里有the number of 和a number of 的区别
1.the number of表示“……的数量”，跟复数名词连用作主语时，中心词是number，谓语动词要用单数。例如:

The number of students in our class is50.我们班学生的数量是50人。

The number of pages in this book is 60.这本书有60页。

2.a number of表示“许多”，相当于 many，修饰可数名词复数。作主语时，谓语动词用复数。number前可用large，small等修饰，以表示程度。例如:

A number of students are planting trees on the hill.许多学生在小山上植树。
