If the number of bobcats increased, the number of plants would decrease in bottom-up model but increase in a top-down model.

What is the bottom-up model and top-down model?

The bottom-up model refers to the model where changes affect the bottom to the top.

The top-down model is the model in which changes affect the top before the down first.

Considering the grassland with five trophic levels:

  1. grasses,
  2. mice,
  3. snakes,
  4. raccoons, and
  5. bobcats.

Grass is at the bottom whole bob-cats are at the top.

Using a bottom-down model, if the number of bobcats increased, the number of plants would decrease.

Using a top-down model, if the number of bobcats increased, the number of plants would increase.
