Answer:
A transect is a line across a habitat or part of a habitat. It can be as simple as a string or rope placed in a line on the ground. ... A quadrat has been placed at regular intervals of a metre (or a few metres) along the transect. A gradual change in the distribution of species across a habitat is called zonation.

HEY MAYE... HERE'S YOUR ANSWER...!!
In transect surveys, students stretch a string across a piece of ground, stake each end, and count the living things that are either underneath the string or within arm's length of it. In quadrat surveys, students map out a square piece of ground and survey the living things lying within the square.
