Imagine that a new herbicide used by local farmers wiped out much of the grass in this ecosystem. What impacts would that have?

The loss of grass in the ecosystem due to the new herbicide can have several impacts.

Firstly, as grass is one of the primary producers in the ecosystem, the loss of grass can lead to a reduction in the energy available to other organisms in the food web. This could have cascading effects throughout the ecosystem, potentially leading to population declines and/or extinctions of other species.

Secondly, grass plays an important role in preventing soil erosion and promoting soil health. The loss of grass could lead to increased erosion, nutrient depletion, and decreased soil productivity.

Thirdly, the loss of grass could have impacts on the water cycle in the ecosystem. Grass helps to absorb and retain water, and its loss could lead to decreased water quality and quantity, affecting aquatic species and potentially leading to changes in hydrological patterns.

Overall, the loss of grass due to the new herbicide could have significant ecological impacts on the ecosystem and its inhabitants.
