Gause's principle of competitive exclusion is, essentially,

#Section 1: Ecology
  1. The more abundant species will exclude the less abundant species through competition
  2. Competition for the same resources excludes species having different life styles
  3. No two species can occupy the same niche indefinitely when resources are limited
  4. Larger organisms exclude smaller ones through competition as in the case of large trees controlling underbrush

In a hypothetical situation, a bacterium lives on the surface of a leaf, where it obtains nutrition from the leafʹs nonliving, waxy covering, while inhibiting the growth of

other microbes that are plant pathogens. If this bacterium gains access to the inside of a leaf, it causes a fatal disease in the plant. Once the plant dies, the bacterium

and its offspring decompose the plant. What is the correct sequence of ecological roles played by the bacterium in the situation described here? Use only those that

apply.
