Simplify the following text for a Grade 3 native English-speaking person.
Original: Insects can get trapped in spider webs , providing nutrition to the spider ; however , not all spiders build webs to catch prey , and some do not build webs at all . The main difference between spider webs and cobwebs is that spider webs are still in use , while cobwebs are webs that have been abandoned .
Simplified: Most spider webs are very thin , but are also very strong .
