The Water Content of Soil
The water content of soil is a major factor that will determine what
sort of plants are able to grow, and when considering a system of sand
dunes will have considerable effects on the zonation and succession of
that environment. In order to investigate this, trial experiments were
initially carried out in order to determine the most effective method
of assessing a section of the dunes and obtaining results. Once these
results had been obtained, adjustments to the original method were
made, and the process of gaining results took place.
After tabulating the results, and drawing appropriate graphs, I
concluded that within a system of sand dunes, zonation and succession
of plant species is present, and as the distance from the strand line
increases, so too does the water content of the soil. I also concluded
that the water content of the soil is affected by the aspect of its
position as well, which relates directly to its exposure.
Planning
Aim
An experiment to investigate how the water content of soil within a
system of sand dunes affect zonation and succession.
Introduction
This investigation will take place on the southern coast of the Gower
Peninsula, at Oxwich Bay where an extensive system of sand dunes is
present. In order to complete a successful experiment with accurate
results, the investigation must be carefully planned out.
The complex structure and ecosystem of sand dunes must firstly be
researched and studied, drawing conclusions and predictions from any
information gained. Selecting the appropriate variables must also be
considered, while taking into consideration the relevant information
gained from the background information, and results from trial
experiments.
Biological Knowledge
The following biological knowledge is all directly related to this
investigation and is essential for predicting trends, and being able
to give some sort of explanations for what is seen.
Community Ecology And Succession
A community is a group of interacting populations living in any given
area representing the living part of an ecosystem.
Investigation to Find the Water Potential of a Root Vegetable Introduction Water potential is the tendency of water molecules to move from one place to another. Osmosis is the movement of water molecules from a region of higher water potential to a region of lower water potential through a partially permeable membrane. I will be investigating the water potential of a carrot to find out at what concentration of salt solution (molar dm-3) equilibrium can be sustained between the net movement of water molecules in to the carrot cells, and the net movement of water molecules out of the cells, therefore finding out the water potential of the carrot, and at what concentration of salt solution the movement of water molecules ceases, and what concentration the water is at inside the carrots cells. I will need to include and explain the relevant AS knowledge demonstrated by this investigation. This includes ideas about osmosis, explaining also how this can affect the structure of plant cells, and showing extremes such as plasmolysis.
Of course, you can’t forget the abiotic factors! Basically, just telling a bit more about the landscape. First, we have the physical features. The landscape of the slope impacts plant growth, hurts natural ecosystems by erosion, and unfortunately destroys the homes of animals. Although, animals and structures adapt to the slopes. T...

Ecology is a strong literary element in the novel Dune. plays a quite large part in Dune. Dune is a desert world, a sterile planet, devoid of life. Not uUntil one goes underneath the surface of Dune, then a whole new ecosystem is seen, based around water or the avoidance of it. Fremen use technology called "stillsuits" to conserve their body's water. Stillsuits recycle any moisture that is excreted by the body. This water is then drunk again, and used again. The Fremen, used to life that requires hoarding water, are astonished at the fact that there are other planets with open water on them. Sandworms are a quite important part of Dune's ecosystem. They, wWhile infants, sandworms produce the spice melange, the spice so precious to human life on Arrakis. These infant sandworms, after being in a spice blow and surviving, eventually grow into the monstrosities that are adult sandworms, the "Old Men of the Desert." (citation) The Water of Life is a potent poison and prescience drug, only obtainable by drowning a sandworm. Its opposite is the Water of Death (citation), ...

Have you ever stopped and thought, “ what would i do if my kid had a disability?” Or ever question why you act a certain way or if you 're strong enough? In the Articles “Notes From a Dragon mom, What we hunger For and the speech “ This is Water” These authors all share there thoughts on what makes a person act the way they do.

The next topic for discussion in this paper is ecology. This will include, preferred habitats and interactions with abiotic and biotic elements of the environment.
A greater abundance and variety of organisms was present in the lower shore rock pool, this was due to the lower rock pool being a more benign environment than that of the upper shore. This was related to the exposure time of the two pools. The rock pool of the upper shore was exposed for longer and therefore suffered greater from variation of abiotic factors, as a result, the organisms of the upper pool had to possess special adaptations to colonise the area. The lower rock pool generally contained different species
Water is a good solvent and picks up impurities easily. Pure water -- tasteless, colourless, and odourless -- is often called the universal solvent. Dissolved solids" refer to any minerals, salts, metals, cations or anions dissolved in water. Total dissolved solids (TDS) comprise inorganic salts (principally calcium, magnesium, potassium, sodium, bicarbonates, chlorides, and sulphates) and some small amounts of organic matter that are dissolved in water. TDS in drinking-water originate from natural sources, sewage, urban run-off, industrial wastewater, and chemicals used in the water treatment process, and the nature of the piping or hardware used to convey the water, i.e., the plumbing. In the United States, elevated TDS has been due to natural environmental features such as mineral springs, carbonate deposits, salt deposits, and sea water intrusion, but other sources may include: salts used for road de-icing, anti-skid materials, drinking water treatment chemicals, storm-water, and agricultural runoff, and point/non-point wastewater discharges. In general, the total dissolved solids concentration is the sum of the cations (positively charged) and anions (negatively charged) ions in the water. Therefore, the total dissolved solids test provides a qualitative measure of the
What do you think of when you hear the term “dirty water”? The term “dirty water” is primarily associated with developing countries, Africa being an example.. As of now, us Americans can assume that since we are a first world country, we will always have a basic necessity- clean water.
Water Scarcity is harmful to human life because when water is poorly managed throughout the world, those who need water are deprived of nutrients they truly need causing them to die. This eventually affects the global population. Therefore many experts have proposed several solutions such as the LifeSaver Bottle, TrojanUVPhox treatment system, and Waste Water Recycling.
Agriculture also leads to soil erosion, both through rainfall and wind. This soil can damage the aquatic ecosystems it ends up in, an...
