front 1 What's the difference between interspecific and intraspecific competition? | back 1 Intraspecific competition is within the same species while interspecific competition is between different species. |
front 2 What makes water and space resources for plants and animals but not temperature, pH and salinity? | back 2 Water and space can be used or consumed but not temperature, pH or salinity. |
front 3 Explain the competitive exclusion principle. | back 3 In a situation where two species are limited by the same resource one species will always end up dominating while the other dies out. |
front 4 Why did Darwin think closely-related species would | back 4 "...because, he reasoned, they possess similar traits, probably consume similar resources,..." |
front 5 What do the a and β variables in competition equations represent? What do they allow you to do? | back 5 They represent the number of individuals of a species. They allow you to convert between the number of individuals of two species (like mole ratios in stoichiometry). |
front 6 List three reasons why the simple 2-species competition model has limited use for predicting outcomes of competition in nature. | back 6
|
front 7 Give an example of a trade-off between competitive | back 7 The most competitive animals are the most likely to get noticed by predators because of their generally higher activity levels. |
front 8 What is exploitative competition? | back 8 When individuals consume and drive down the abundance of a resource to a point that other individuals cannot persist. |
front 9 What is interference competition? | back 9 When competitors do not immediately consume resources but defend them from others. |
front 10 What is apparent competition? | back 10 When two species have a negative effect on each other through an enemy—including a predator, parasite, or herbivore. |
front 11 If two competing species can both be infected by the same parasite what might we see in a case of apparent competition? | back 11 In places where both species are present a difference in parasite resistance/tolerance may cause one species to suffer while the other flourishes. |
