Let's take a look at the sentence you gave: "With its fluffy mane and a loud roar, a lion looks like a king and because of its, people call it the king of beasts."
There are a couple of small grammar mistakes. Here's the corrected sentence:
"With its fluffy mane and loud roar, a lion looks like a king, and because of this, people call it the king of beasts."
Explanation for the changes:
- We removed the extra a before loud roar because it sounds better without it.
- We added a comma , before and to connect the two parts clearly.
- We changed because of its to because of this to make the meaning clear. Its means something belongs to the lion, but this points to the loud roar and fluffy mane we just talked about.
So now, the sentence is clearer and easier to understand!
