between the two species? (1 point) To determine which plant species was most
negatively affected by interspecific competition would require dividing the total
biomass per pot by the total number of seeds per pot to determine average
biomass. The results are provided below:


Seeds   per Pot Average Biomass (g)
1 radish

5.0


1   wheat

3.0


10  radish

5.0


10  wheat

2.5


20  radish

3.8


20  wheat

2.0


From the table, it appears that the wheat seedlings were negatively impacted by
the presence of the radish seeds. When graphed, the results are:
