The livestock waste fertilizes  the grasses

Explanation:

A negative ecological impact is one that is detrimental to the ecosystem or that results in a disadvantage to organisms in the ecosystem.

When livestock graze on rangelands, it would result in both positive and negative impacts to the rangeland.

Some of the negative impacts includes those listed in the options. For example:

1. The weight of the grazing cattle as they move around to graze will compact the soil. This compaction of the soil will reduce aeration of the soil as well as the fertility of the soil.

2. The livestock may eat too much grass which is known as overgrazing. Overgrazing will not give the plants enough time to regrow before they are eaten. this will eventually result in too few grasses growing in the rangeland.

3. Increased wind and water erosion due to overgrazing. as the livestock graze, they remove grasses which help to reduce wind and water erosion on the soil. This results in loss of soil fertility.

However, an advantage of grazing on the rangeland as the livestock graze is that the wastes of the livestock serves as a source of manure for the grasses which fertilizes the soil and makes the grasses grow.
