Answer :
Answer:
Dung burial increases the rate of nitrogen volatilization into the atmosphere.
Explanation:
Dung burial increases the rate of nitrogen volatilization into the atmosphere because dung burial is the activities performed by beetles by incorporating and burying manure or dung inside the soil. As the beetles perform this activities, by burying and burrowing in the soil,the soil are exposed and allow aeration of the soil. Once the soil are aerated, nitrogenous compounds in the soil turns to nitrogen gas i.e they volatise into the atmosphere as nitrogen gas.
Final answer:
Dung burial improves range animal productivity primarily because it reduces the habitat for some life stages of parasites, which in turn protects livestock from diseases and promotes healthier grazing environments.
Explanation:
The mechanism that explains why dung burial improves range animal productivity is that dung burial reduces habitat for some life stages of parasites. By burying dung, dung beetles and other soil invertebrates indirectly protect livestock from pests, such as flies and parasites that develop in and are attracted by dung. This activity improves nutrient recycling and soil structure, which in turn supports healthier range environments for animal grazing.
Moreover, the reduction of habitat for parasites due to dung burial helps in maintaining the health of the grazing animals by decreasing their exposure to diseases that might be transmitted by these parasites. This improvement in the health of animals leads to better growth rates and increased productivity on the range. Additionally, the process contributes to a healthier soil ecosystem, which is crucial for plant growth and the overall productivity of the range.
