Predator-Prey Interactions, Different combinations of predators (P) and…

- - - - searching efficiency of predator
      - predator attack rate
- - - - • Consumption rate increases as prey density increases.
      - • Gradually decelerates until plateau reached.
      - • Consumption rate constant irrespective of increasing prey density.
    - - • At low prey density, Type 3 has an accelerating consumption phase
      - • Rate is greater than linear; predators better at predating.
      - • At high density the shape is the same as Type 2.
      - • High victim abundance, predators can’t control population growth
    - - • Constant volume of water, yeast cells eaten increases linearly
      - • Above certain density, can’t ingest yeast fast enough
- - - - If fewer predators than r/a (below), victim abundance
        INCREASES
      - If more predators than r/a (above), victim abundance
        DECREASES
