Question

Quizplus · Accepted Answer

By removing grass blades, grazers allow more light to reach the remaining grass which can stimulate growth and improve the overall health of the grass population. This can also increase the photosynthetic activity of the remaining grasses, resulting in more energy being available to support the ecosystem. Trampling the grass and increasing erosion or compacting the soil can decrease the health and productivity of the grasses, while selective grazing or removing live grasses can impact the diversity of the ecosystem and potentially harm other species that rely on the grasses. Therefore, the most beneficial action for the grass species would be to remove grass blades.
