Which taxa would include more species: Order or Phylum? *

Phylum

Explanation:

Think about the taxonomy pyramid as a filter: the filter with the most holes is the Domain, which means animals, or coffee beans can go through easily. But as you move down the triangle, the filter becomes finer, so we are picking through the coffee beans for specific ones only.

Phylum is more "course" than Order, in which the people are more selective about the "coffee beans".

Below is an image of the triangle in case.

Hope the example helps!
