Answer:
For most crops the saturation point will be reached at about 1,000–1,300 ppm under ideal circumstances. A lower level (800–1,000 ppm) is recommended for raising seedlings (tomatoes, cucumbers and peppers) as well as for lettuce production

Explanation:
Random distribution of the Isopods should be 50/50 in A and B.
Chi-square =  where O = observed frequency and E = expected frequency
 where O = observed frequency and E = expected frequency
Chamber         O                    E             Chi-square
   A                   18                   10              = 6.4
 = 6.4
   B                    2                    10              = 6.4
 = 6.4
<em>Total Chi-square </em>= 6.4 + 6.4 = 12.8
<em>Degree of freedom</em> = 2 - 1 = 1
<em>Tabulated Chi-square</em> (α = 0.05) = 3.8415
The calculated Chi-square exceeds the critical value, hence, it is significant and not due to random.
<em>The correct option is </em><em>c</em><em>.</em>
