Document Summary
E) parasites can do d) which puts smaller popul"ns more at risk. Organisms can be seeds as well (if u eat a seed, its included as predation) Learning objectives: define / give significance of red terms, differentiate between predation, grazing and parasitism, and between generalists and specialists, describe examples of predator adaptations and prey counter- adaptations (including to herbivory). Relate to red queen hypothesis (arm"s race): discuss how predation and herbivory can impact prey fitness / abundance. Describe how this can lead to prey cycles: discuss how predation can impact community structure (especially with respect to the effects of predator-mediated coexistence). Predation: when one individual benefits (gains resources) by consuming part/all of another organism (+/-) Kill prey quickly, consume many prey over life time: true predation. Examples: carnivora (mammals), zooplankton, squirrels, raptors (birds), and other seed eaters: herbivory/grazing grazing describes herbivory but u can also graze other animals (1 time grazing of animals won"t kill it)
