A student investigates plants growing underneath a tree He lays out a tape measure on the ground, starting at the tree. He then places a quadrat on the ground. He measures the percentage of the ground in the quadrat that is covered by plants. He repeats this every metre away from the tree. The table shows his results. The student thinks that shade from the tree is affecting the plants. Explain how the student’s results show this. – 7619
