Calculate competition coefficients and graph , please help!
Thank you !

1. Plant species 1 and plant species 2 are arown in pots, either alone or in competition When grown alone, species 1 stabilizes at 20 plants per pot, and species 2 stabecies 2 30 plants per pot. Whe n grown together, species 1 has an average of 15 and species 2 an average of 20 plants per pot. Calculate the competition coefficients for these 2 species 2. Diagram the interaction above on the graph provided. Be sure to calculate both endpoints of each of the two isoclines and place them appropriately on the graph.
