Question

Question 1 (1 point) Energy spent on reproduction constitutes an organism's "reproductive effort". The figure below shows the relationship between reproductive effort (number of cones produced) and growth measured as the relative width of annual rings for the Douglas fir, Pseudotsuga menziei. The line represents the general trend as defined by the equation: y -1.70x+ 107.5; n- 32, 2 0.71, P 0.008. 120 115 110 105 100 95 F 90 85 80 75 0 2 46 8 10 12 14 16 18 20 22 Mean number of cones per tree (10)

Explanation / Answer

Please find the answers below:

Answer 10: Choice b (The negative slope of the graph between the number of annual rings and the reproductive potential of the plants represents that these two entities are negatively related to each other. The equation of slope, thus, represents that the quantitative decline in the number of rings is by 170 units)

Answer 11: Choice a (since the study was designed to investigate the hypothesis that a large part of plant energy is driven to confer reproductive success to it, the data suggesting a negative regulation between reproductive success and plant growth proves the hypothesis true)
