Question

p. aurelia and p. caudatum grown separately p. aurelia and p. caudatum grown together relative population size relative population size p. aurelia p. aurelia p. caudatum p. caudatum 0 20 0 20 number of days number of days graph c rate of growth of r. tigrina tadpoles in populations of different sizes. 1.0 mean body mass (g) minimum mass needed for metamorphosis to occur. 0.8 0.6 5 individuals 40 individuals 60 individuals 160 individuals 0.4 0.2 0 1 2 3 4 5 6 7 8 9 10 time (weeks) 14. what are the names of the species in graphs a and b in model 3? 15. which graph shows competition between two different species?

Explanation:

1. From the labels on graphs A and B, the species are P. aurelia and P. caudatum.
2. When two species are grown together and their population - size changes are shown, it indicates competition. Graph B shows P. aurelia and P. caudatum grown together, so it shows inter - species competition.

Answer:

1. The species are P. aurelia and P. caudatum.
2. Graph B.
