Model 1# of hares (in thousands)# of lynx (in thousands)103 , which is 1000160 (x1000) = 160,0004-5 (x1000) = 4-5,000In 1885, horseshoe hare population was about 135,000 (way above average) the lynx population was 6,000 (also way above average). This trend continues for all years sampled. The trend being that when the hare population is high so is the lynx.In 1990, hare population was only 10,000 (way below average). The lynx population in 1900 was 2,000 (also way below average). The same trend follows suit. As hare population declines so does the lynx population.An obvious relationship is that lynx eat hares. As the population of hares increase, the available food supply for lynx increases making it easier for the lynx population to support young. This causes the lynx population to increase with the hare population. But when lynx populations get too big they overeat. This causes the hare population to dwindle.The information tells us:Prey population size causes the predator population to rise.The predator population causes the hare population to shrink.There is an increase in competition over available food, shelter, and mates (among others like disease spreading, etc.).Model 2Fleas benefit, dogs don’tDogs are harmedTapeworm and humansModel 2Both organisms benefitNoTermite and bacteriaModel 2Benefit goes to the remoraNoCattle and the egretright762000ParasitismMutualismMutualismCommensalismCommensalismParasitism 020000ParasitismMutualismMutualismCommensalismCommensalismParasitism 670560000.Your justification will be unique but you should provide an explanation based upon the definitions of the symbiosis and the information in the chart. Mutualism means both parties benefit, commensalism means one benefits and the other is not harmed not benefits, and parasitism means one benefits and the other suffers.P. Aurelia and P. caudatumGraph BGraph A (& C, technically)In Graph A they are grown separately, in Graph B they are grown together.P. AureliaIs 20% significant? Technically, yes. But for our purposes, not really.Model 3. Graphs A & BP. caudatumP. Aurelia is more successful than P. caudatum when they are placed in a competitive environment because… (your answers will vary).Interspecific competition is competition between 2 different organisms.Model 3. Graph CA species of frog.Most likely, food since size is the dependent variableJust below 0.8 grams (g)2 ? weeks6 ? weeksOver 8 weeksMost likely, the tadpoles do not get enough nutrients to obtain the minimum body mass necessary for metamorphosis when there is too much competition.Graph B is the competition between two species. One will win and one will lose. In Graph C, there is only one species competing. The more of that organism causes a more dramatic effect on competition. B. rigidus is more successful when planted “head-to-head” with B. madritensis. However, when madritensis is allowed to establish itself (allowed to develop for 30 days) it has consumed enough area, enough resources, or otherwise is strong enough to outcompete rigidus. This accounts for why rigidus dominates when planted at the same time but is completely dominated when planted after 30 days of madritensis growth.right1288626Planted 30 days later, rigidus can’t compete with madritensis.020000Planted 30 days later, rigidus can’t compete with madritensis.2768389314960Planted at the same time, rigidus dominates.020000Planted at the same time, rigidus dominates. ................
