1. The correct answer is B. Conservation tillage practices help the soil erosion and also maintains soil nutrient levels.
Conservation tillage is termed as the tillage system which helps to conserve energy, soil, water through retention of crop residue and reduction of tillage intensity.
2. Correct answer is A. Aquifers 1 and 3 may result in a reduced river flow. Aquifer is termed as the underground layer of rock fractures, water-bearing permeable rock.
Hydrogeology is termed as study of water flow which is found in aquifers.
3. Correct answer is A. Recycling materials helps decrease the amount of new material which are taken from environment.
Most household can be recycled. Some other examples which are recycled include textiles, plastics, organics, and metals. Metals such as drinking bottles and food cans which are made from steel and aluminium can be recycled.
Explanation:
Cardiovascular disease. Cardiovascular disease (CVD) is a general term for conditions affecting the heart or blood vessels. It's usually associated with a build-up of fatty deposits inside the arteries (atherosclerosis) and an increased risk of blood clots.
CURES:
Although we can't cure heart disease, we can make it better. Most forms of heart disease are very treatable today. There is some evidence that normalizing high blood pressure and lowering cholesterol to very low levels will partially reverse plaques in the coronary arteries. ... We can repair or replace diseased valves.♥️

Part D
Management of natural resources can affect the sustainability of human populations. For example, consider an effort to decontaminate a small village’s water supply. This effort is projected to increase the carrying capacity from an initial population of 400 people (P = 400) to 450 people (K = 450) during the course of 10 years (x = 10). Use the simulation to determine the growth rate r of the population in this village. Round your answer to the nearest whole number. (Hint: Use the tool's zoom feature to get a closer look at the curve.)

Part E
Technological advancements can help make consumption and management of natural resources more sustainable, as discussed in part C. As technology enhances renewable, sustainable energy sources, how will this likely affect the carrying capacity and growth rate of the human population over time?
Part F
Read this below about biodiversity, and then answer the following question.
“The Midwest is helping to pioneer the biofuel movement in the United States. Burning biomass—a natural resource—for fuel doesn’t emit additional CO2 into the atmosphere. However, biofuel production reduces the area’s biodiversity because corn, which is a primary source of biomass, is overplanted. Grasslands and fields once inhabited by a large variety of flowers, grasses, insects, and pollinators are being cleared as the demand for corn increases. The impact of eliminating these species and decreasing the area’s biodiversity then spreads as other plants and crops that relied on the insects and pollinators are threatened. These negative consequences can then magnify throughout the ecosystem.”
If an ecosystem is no longer able to sustain its biodiversity, what potential impact could that fact have on the carrying capacity and growth rate of the human population over time? As you answer, think about how the energy is transferred through an ecosystem.
Part G
Write one to two paragraphs describing the relationship between the management of natural resources, the sustainability of the human population, and biodiversity. Use your work from parts A through F to guide you.
In order to maintain the ecosystem carrying capacity and ensure the long-term existence of humanity, natural resource management should work to improve sustainability and biodiversity.
The sustainability of both human populations and wildlife depends significantly on how natural resource management is carried out. The carrying capacity of the ecosystem and the rate of population growth are both impacted by the depletion of natural resources.
The sustainability of natural resources can be improved by technological developments, particularly in the field of renewable energy. The ability of the ecosystem to support life and its biodiversity could both be impacted by the development of biofuels.
The entire food chain may be impacted by biodiversity loss, lowering the amount of resources available to the human population. In order to maintain the ecosystem's carrying capacity and ensure the long-term existence of humanity, natural resource management should work to improve sustainability and biodiversity.
