PLEASE HELP A student carries out an experiment. She clears an area of soil in her
backyard. She keeps the soil watered and makes careful weekly
observations of the area. She uses a notebook to record data about the
plant growth in the area of study. Originally she observes only worm and
insect activity in the soil. After 2 weeks she notices the growth of grass
and weeds in the soil. She also notices an increase in insect activity in the
area. She continues her observations over a period of three months. By
the end of the experiment, the soil is almost completely covered with
grass and weeds. She also notices that some tree seedlings have taken
root and are beginning to grow. On the final day of her observations, she
notices a rabbit eating the grass. Which of the following would the student
be able to analyze by looking at her collected data? *
