Based on your data, which type of soil do you think is best for agriculture? Explain your answer. Loam would be the best kind of soil to plant crops in because it is permeable but it takes low amounts of water to irrigate the soil. Farmers often have problems with soil erosion when they clear their fields after the growing season. Soil type is one factor that influences erosion.
Plants are the producers for an ecosystem. They photosynthesise carbon dioxide and water and produce energy in the form of carbohydrates and other molecules. Photosynthesis requires water, and plants gain water from the soil using mineral ions such as nitrate produced by the nitrifying bacteria. Hydrolysis of ATP releases energy for processes such as active transport of the nitrate ions (and others such as potassium etc) from the soil into root hair cells, a process that lowers water potential and is used to draw water into the plant from the soil. In leaves, photosynthesis involves the photolysis of water, a process that involves the attachment of two electrons to a magnesium ion in chlorophyll and the production of hydrogen ions from the breakdown of water.
Alkalinity can be defined as the capacity to neutralize acids. Carbonates (CO32-) are a major constituent in natural water that helps it behave as a buffer. Acid rain can reduce the alkalinity of water and hence would decrease its pH. In this experiment, water sources that measure pH below 5.6 will be considered acidic precipitation. Water from a variety of sources that receive precipitation is being sampled.
The sweet potato industry, although a high value industry, is becoming increasingly competitive. This underlines the importance of efficiency in minimising the loss of valuable soil. Large amounts of rainfall can result in the loss of soil on cultivated farmland. The loss of soil does not just affect the farmers it also affects the community The aim of the project was to increase awareness of soil health and to develop the best soil management practices for the Cudgen plateau. Figure [ 2 ] Water Way On the Cudgen Plateau, three adjoining landholders implemented soil conservation measures and strategies.
Aims Aim 1: To identify and prepare a natural indicator using red cabbage. Aim 2: To use the natural indicator and two other commercial indicators (universal indicator and phenolphthalein) to classify five household substances as acidic, basic or neutral. Background information An indicator is a substance that, in solution changes colour depending on whether the solution is acidic or basic . Many plants and flowers have natural substances which have indicating properties that allow them to be used as indicators . One of the best natural indicators can be extracted from red cabbage.
Vegetables have very good nutrients so when picking vegetables one should choose a variety of colors to get a variety of nutrients. Vegetables Lower blood pressure; reduced risk of heart disease, stroke, and probably some cancers; lower risk of eye and digestive problems; and a mellowing effect on blood sugar that can help keep appetite in check. Last but not least is my grain intake. My grain intake is the equivalent to 5.4 ounces and my recommended amount of grain intake is 6 ounces. I need a little more grain consumption to meet my recommended amount.
It is also essential to understand how to separate and identify different bacterium among a sample in order to treat each bacterium separately. Introduction For this project the researchers were provided with a mixed sample of a gram-positive and gram-negative bacterium and given the task to separate and identify them. Gram-positive and gram-negative bacteria differ in the environments and nutrients that are needed to grow and those that will impede growth. To differentiate between the two types of bacterium a gram stain was performed, then selective media were used to separate and identify both bacterium. Selective media contain specific nutrients or ingredients that allow for the growth of a specific organism or a particular type of
If an ideal pH level is 7 than the carbon was able to take our acidic water and make it more neutral. Coal works as a pH balancer for the earth’s soil and helps to filter out water as it passes through. The pH in the soil has a major impact on the nutrients that come from that soil. The more nutrients that are produced the better ecosystem will function. 4.
The shape of a cell is related to its function because of the adaptations made throughout time to make the cell as efficient as it can be. There are two types of cells, eukaryotic cells, which are generally plant and animal cells and prokaryotic cells which relate to bacteria and fungi, which undergo asexual production. Plants are anchored into the ground by roots. The function of roots is the transportation of water and mineral ions from the soil into the xylem to transport around the plant. The roots have an outer layer of cells called root hair cells that have a specific shape that makes the uptake of water and mineral ions more efficient.
They form a mutualistic relationship with the plants, they provide the plant with nitrogen and the plants provide them with carbohydrates. The second stage is ammonification where nitrogen sources in dead organisms are turned into ammonium compounds by decomposers. The third stage of the nitrogen cycle is nitrification. Nitrifying bacteria convert ammonium compounds to nitrites, and then other nitrifying bacteria convert these to nitrates. The last stage is denitrification where nitrates in the soil are converted into nitrogen gas by denitrifying bacteria that use the nitrates in the soil to carry out respiration and produce nitrogen gas.
