Rainwater is normally free from dangerous substances, which makes it perfect for irrigation schemes. Added significant benefit is that it decreases the requirement for fresh water. It is important particularly in regions with low water levels.
Another benefit might water harvesting have in these areas with land erosion due to runoff are as follows;
Reduces Water Shortages
In temperate areas, the strain on public water supply can become hard, even in advanced countries. Rainwater decreases the uncertainty of water shortages. Using rainwater for non-essential actions such as spraying the lawn means less pressure on the supply of safe drinking water.
Replenishes Groundwater
Extensive rainwater harvesting projects with the water collected into storage containers or tanks are important to assure a sustainable groundwater level.
Reduces soil erosion
Heavy rainfall generates erosion because some of the soil is transferred along with the passage of water. Soil erosion exhausts agricultural land of topsoil and nutrients, provides to sediment build up in waterways and, in advanced cases, can turn land inadequate for agriculture. Harvesting rain checks a great chance of soil erosion before it can originate.
I believe the answer is tertiary
Answer:mutualism
Explanation:
In a mutualistic relation,both organisms involved benefit from the activities of each other. The benefits may be nourishment,shelter, protection etc.
In the above example,the birds are known to guide humans by responding to specific calls made by the human. They guide humans to beehives and then in return gets to feed on left over honey. Both the bird and human benefits by getting nourishment.
Mutualism is unlike parasitism where one of the organism involved benefits and the other organisms Is most likely harmed. It is also not commensalism, where one organism benefits and the other neither benefits nor is harmed
Due to its short life cycle this fly can easily multiply if its population is not controlled. <span>The house fly is known to carry more than 100 diseases including tuberculosis and cholera</span>
Natural landscapes such as forests, the soil absorbs much of the stormwater and plants help hold stormwater close to where it falls. In developed environments, unmanaged stormwater can create two major issues: one related to the volume and timing of runoff water (flooding) and the other related to potential contaminants that the water is carrying (water pollution).
