B

Explanation:

The correct answer would be that the removal of producers will affect all other trophic levels.

Cacti belong to a group of organisms known as the producer because they have the capacity to manufacture their foods through photosynthesis. The producers form the basis of a typical food chain on which other organisms in the food chain directly or indirectly depend.

The removal of cacti will lead to a reduction in the number of producers in the environment and this will directly impact the organisms in other trophic levels whose source of energy directly or indirectly depends on the producers.
