 The most important contribution the ants make to the plants they inhabit is not protection, but feeding the plant itself.The organic material that the ants contribute to the plant falls into three categories; nest building material (material such as leaves, bark, or other plant matter), ant-created products (such as waste, dead enemies, or the bodies of dead ants), and the final category is food that the ants themselves consume.All of these waste products stored within the rough-walled chambers begin to decompose when moisture is present, and are then broken down by microbial activity and the nutrients are then taken up by intrusive adventitious roots or absorbed through wall linings (rough-walls with root "bumps" lining the chambers).
