B. Draw pictures.

Draw a picture of a spider’s web.
Find out why a spider weaves a web. Under the picture, write the information you get.

Ans: The web of the spider is produced from the sticky secretion prepared in the body of the spider. The prey of a spider gets caught in the web. There are some sticky substances, due to which the prey cannot escape once caught. Thus, for feeding purposes, spiders weave their webs. The spider also lays its eggs in the cocoon, which are placed in the web.
