Idon’t get this can someone explain would be appreciated : )

Answer part A:
                       
                     Genotype ratio:

                                               TT (Homozygous tall plant)
                                               Tt (Heterozygous tall plant)
     
                Phenotype ratio:
                                                4 tall plants

Answer part B:

                         If Tt and Tt plants are crossed with each other then they can produce short offspring, as shown in punnet square 
                        
                              Tt          X           Tt

F1 generation
                               TT, Tt, Tt, tt

Result:

            It is clear from F1 generation that one offspring (tt) is short. 

Yes i do hahahahahhaha

The rate that would change would be the  searching efficiency/attack rate. there are only two other rates in this model: the  growth rate of prey, and the  predator or consumer mortality rate.the  searching efficiency/attack rate is what indicates how effectively can a predator capture its prey whether in the searching process or actual capturing/attacking process.
