Case I: Competition for food between two species of trout,

Last updated: 8/7/2022

Case I: Competition for food between two species of trout, bull trout and brown trout, led to the local extinction of bull trout. Bull trout were out competed for resources by brown trout. Case II: Competition for food between two species of barnacles, Chthamalus and Balanus, did not lead to the extinction of either species. Instead, the species both survived in the same region although the density of one of the species varied at times. From the above information, what can be inferred about the ecological niches in each case? Case I: The ecological niches of the two species were similar. Case II: The ecological niches of the two species were very dissimilar. Case I: The ecological niches of the two species were very dissimilar. Case II: Tthe ecological niches of the two species were similar. Case I: The ecological niches of the two species were similar. Case II: The ecological niches of the two species were overlapping but not completely similar. Nothing can be inferred about the ecological niches.
