People Buy Me to Eat

I live in Africa. I am Yellow and Brown.

I eat leaves. I have a long neck.

Who I am?

I am a huge hot star in the solar system.

You don't look directly on me. I can hurt your eyes.

Who am I?

How many seconds are there in one year?

I am a desert animal. I am tall.

People like to ride on me. 

Who I am?

What has to be broken before you can use it?
