Caught in a web

When people die
Where do they go 
Into the ground
Places we know 
??????
These stars in the sky 
How did they once form 
A simple why 
Explains a life born 
??????
The rooster crows 
The duck does quack 
A horse bellows as the 
The cat on my lap 
??????
I can see a camel 
Walking the long grass 
As does a mammal 
Through the days of loss 
??????
The most irritating creature
The fly on the leg 
Unfortunately does feature 
Until caught in a web
