Correct sentence: Ospreys love fish. They grab fish right out of the water.
Why this is better (in simple steps):
- Capitalize the first word: Every new sentence should start with a big letter. So they becomes They.
- Make the words agree: "Ospreys" is plural (more than one bird), so we use the plural pronoun they (not it). Also we can say fish again instead of it, or use them if you want a pronoun: "They grab them right out of the water."
- Punctuation: Keep the period at the end of each sentence.
Other good versions:
- Ospreys love fish. They grab them right out of the water.
- Ospreys love fish, and they grab them right out of the water.
Try one: Fix this sentence: "Seagulls eat worms. they peck it quickly."
Answer: Seagulls eat worms. They peck them quickly.
