Energy is not distributed evenly through the ecosystem; lower levels gain more energy than higher ones. Most ecosystems rely on the sun for energy and for the plants (producers) to convert it into energy to be passed along to primary consumers, and from primary consumers to secondary consumers and so on. The producers are autotrophs and photosynthetic organisms that can perform photosynthesis in order to grow. Consumers are heterotrophs and feed on other organisms, be it plant or animal. There is another type of organism that cleans up after the others, and they are called detritivores.
Inorganic ions are charged particles that do not contain carbon atoms bonded together. While organisms are mainly built from carbon-containing molecules, their functions rely on inorganic ions such as nitrate, hydrogen and calcium. This essay will detail some of the roles of specific ions and describe how animals, plants and bacteria use them. Productivity in an ecosystem in the soil is limited in part by the availability of fixed nitrogen in the soil. Nitrogen fixing bacteria in the roots of leguminous plants reduce atmospheric nitrogen to ammonium using ATP and reduced NAD.
The substance that absorbs sunlight is chlorophyll, which is mainly contained in chloroplasts. This energy is used to convert carbon dioxide (CO2) and water into sugars. This conversion creates the waste product oxygen, which is used by humans for breathing. Without being able to photosynthesise plants will stop growing and die. In a plant growing in the dark the chlorophyll will slowly be destroyed causing them to use their food reserves.
Oil is a fossil fuel supply which is not being created as fast as it is being drained. It is something that has been the cause of many deaths in two world wars. Hemp could be contributing to our independence in lieu of the government spending money to burn these crops that grow naturally. Some food crop production is being geared toward making a fuel called Ethanol. Ethanol is a healthy alternative to oil.
Phosphate comes from a rock that gradually breaks down and will release other ions. Human impacts phosphorus cycle by using phosphorus containing fertilizers to make animal feed, detergents, and other products. This cycle is a common limiting factor in soils and added to croplands to greatly stimulate the production. When this cycle moves from the soil and gradually makes it way to the ocean, it creates problems such as water pollution. The Nitrogen cycle has similarities to the carbon cycle and the phosphorus cycle.
Unhealthy calories come from unhealthy farms. The system we currently follow is obiously tweaked, and Pollan calls out for a change, but that change must come from the eaters themselves. The food system we currently follow is focused on supplying large amounts of food for a cheaper price, and that usually means that it is not the healthiest. Our plummeting health is the price eaters must endure just to save that extra dollar, or to get a “buy one get one free” product. Never have I seen a bag of spinach or a head of broccoli that was advertised as “buy one get one free.” This is due to the fact that if all of a sudden healthy foods were as cheap as unhealthy foods, people would “vote” differently.
In plants the way they get there energy is through sun light where they have process called photosynthesis where they produce and release oxygen in the air. Photosynthesis requires direct sunlight, carbon-dioxide, and water. In this process of photosynthesis, plants decompose the molecules of hydrogen and carbon dioxide into hydrogen, then carbon and oxygen produces glucose which forms their source of energy, food and growth. Solar cells similar to this process get sunlight where light in the form of photons hits the solar cell and are absorbed by semiconducting materials such as silicon. Negative electrons are break free from their atoms, causing them with an electric potential difference.
Biochar is made by slow cooking plant wastes until it becomes a carbon-rich char that is mixed with soil and buried underground. This process keeps the carbon created by the plant waste in the soil instead of being released into the atmosphere. Charcoal has positive effects on plant life. It adds a source of carbon to plants, speeds water drainage, allows good air flow in the soil and stops the growth of bacteria and fungi. The company Carbon Gold who will help to create the product, states that it is an effective way of removing carbon dioxide from the atmosphere.
(NEGATIVE IMPACT) However, if we decide to shift large quantities of corn to fuel production from food production, humans will be left with no food and this will cause world hunger which even be a worse situation. Basing on the example above, technology by its self is not harmful to the society, but the way society uses technology to achieve specific goals is what results into negative impacts of technology on the society. Humans need to use energy to process products in factories, to run cars , to light homes and also run technological machines like computers, but the only way we can do this without affecting the environment and society , is by shifting from exhaustible energy
People also now use biodiesel for heat; in some areas biodiesel is now cheaper than the other diesel so people try to buy biodiesel for transportation and heating. Biodiesel is made of plants, and crops that contain extraordinary level of sugar. However most of these crops are used as food. Se we may face problems, one major problem is that the more we start using biofuels the higher the prices of food will get. Biodiesel are made from crops and these crops need fertilizers, the ruthless side of using fertilizers is that it may harm the environment and may cause water pollution.
