Question 5 (Matple Choke Worth 3 points) MC) Local ranchers have expanded the grazing area of their cattle. How will this impact the river that runs along their lands? Animal wastes will run into the river with every rainfall This will not significantly impact the river Animal wastes will decompose and add important nutrients to the river Cattle will pollute the river by using it as source of water

Answer 1

The expansion of grazing areas for cattle can have several potential impacts on a nearby river. Let's evaluate each option:1. **Animal wastes will run into the river with every rainfall.** This is a likely scenario. When it rains, runoff can carry animal waste into the river, leading to pollution and potentially harming aquatic life.2. **This will not significantly impact the river.** This is unlikely. Expanding grazing areas typically increases the amount of animal waste, which can affect water quality in the river.3. **Animal wastes will decompose and add important nutrients to the river.** While decomposition does release nutrients, excessive amounts from animal waste can lead to nutrient pollution, causing problems like algal blooms that harm aquatic ecosystems.4. **Cattle will pollute the river by using it as a source of water.** Cattle accessing the river directly can cause pollution through trampling banks and direct deposition of waste into the water.Given these considerations, the most accurate answer is: **Animal wastes will run into the river with every rainfall.**
