The vegetation in a grassland ecosystem consists mainly of grasses, shrubs, and bushes. The prairie dog is a small rodent that g
razes on the grasses found in the North American grasslands. The swift fox feeds on the prairie dog, and is in turn preyed upon by the badger. The golden eagle feeds on the badger. The following graph shows three of these populations declining in size over a span of five years, from the time a disease began affecting the swift fox population in this ecosystem. How would this disease most likely impact the grassland ecosystem? A. The vegetation in the grasslands will increase and soil erosion will decrease. B. The vegetation in the grasslands will increase and soil erosion will increase. C. The vegetation in the grasslands will decrease and soil erosion will decrease. D. The vegetation in the grasslands will decrease and soil erosion will increase.
The vegetation in the grasslands will decrease and soil erosion will increase. Option D
<h3>What is predation?</h3>
Predator prey relationships are common in several ecosystems. Many organisms tend to feed on other organisms and this creates a natural balance in the ecosystem as the population of a given organisms does not swell to an unsustainable height.
As such, if there is a diseases that affects the swift fox population in this ecosystem causing it to decrease, the vegetation in the grasslands will decrease and soil erosion will increase. Option D
A. The vegetation in the grasslands will increase and soil erosion will decrease because of lower population of herbivores.
<h3>How increase in vegetation causes decrease in soil erosion?</h3>
Vegetation protects soil erosion by reducing the energy of raindrops, increasing the water infiltration into the soil and reducing runoff of water on the surface. Plants slow down the water as it flows over the land and this allows much of the rain to absorb into the ground. Plant roots hold the soil in position and prevent it from washed away.
So we can conclude that the vegetation in the grasslands will increase and soil erosion will decrease because of lower population of herbivores.
The Brønsted–Lowry theory is an acid–base reaction theory which was proposed independently by Johannes Nicolaus Brønsted and Thomas Martin Lowry in 1923.
Mendeleev realized that the physical and chemical properties of elements were related to their atomic mass in a 'periodic' way, and arranged them so that groups of elements with similar properties fell into vertical columns in his table.
