Your sentences are mostly correct, but I will suggest a few small improvements to make them clearer and grammatically perfect:
- Original: "Sunny meadows are full of grasses."
Suggestion: "Sunny meadows are full of grass."
Explanation: 'Grass' is usually uncountable, so we say 'full of grass' instead of 'full of grasses' unless talking about different types of grass. - Original: "Their thick growth and nice smell attract a lot of animals."
Suggestion: "Their thick growth and pleasant smell attract many animals."
Explanation: 'Pleasant' sounds better than 'nice' here, and 'many' is preferred over 'a lot of' in writing. - Original: "The grass also gives home to insects and birds."
Suggestion: "The grass also gives a home to insects and birds."
Explanation: Adding 'a' before 'home' makes the sentence clearer.
Here is the corrected version:
"Sunny meadows are full of grass. Their thick growth and pleasant smell attract many animals. The grass also gives a home to insects and birds."
