Structural Biochemistry/Properties of Living Organisms 6. Populations of living organisms adapt to changes in their environment through evolution. As changes occur in the population, the organism adapts, using their abilities to metabolize respond and reproduce. Characteristics that are more useful in survival are passed to offsprings and allows survival for the species.

Why Is Water So Essential for Life? Water, with its amazing dissolving properties, is the perfect medium for transmitting substances, such as phosphates or calcium ions, into and out of a cell. Phases of water. Another feature of water is that it can act as a solid, liquid and gas within the range of temperatures that occur on Earth. Other molecules that have been identified as good candidates for supporting life tend to be liquid at temperatures or pressures that would be inhospitable for most known life-forms, Glazer said.

Water Temperature Heat transfer, whether from the air, sunlight, another water source or thermal pollution can change the temperature of water. Water temperature plays a major role in the quality of aquatic life and habitats. Heat flow and the fluctuation of temperature determine what species will live and thrive in a body of water. Water temperature has been defined as the “abiotic master factor” by JR Brett due to its effect on aquatic organisms 15.

Adhesion and Cohesion of Water Cohesion: Water is attracted to water. Adhesion: Water is attracted to other substances. Adhesion and cohesion are water properties that affect every water molecule on earth and also the interaction of water molecules with molecules of other substances. Essentially, cohesion and adhesion are the stickiness that water molecules have for each other and for other substances. You can see this in the picture to the right. The water drop is composed of water molecules that like to stick together, an example of the property of cohesion. The water drop is stuck to the end of the pine needles, which is an example of the property of adhesion.

Vital Signs: The Five Basic Water Quality Parameters Temperature. Temperature is a measure of the average energy (kinetic) of water molecules. It is measured on a linear scale of degrees Celsius or degrees Fahrenheit. It is one of the most important water quality parameters.Temperature affects water chemistry and the functions of aquatic organisms.alts and other substances affect the quality of water used for irrigation or drinking. They also have a critical influence on aquatic biota, and every kind of organism has a typical salinity range that it can tolerate. Moreover, the ionic composition of the water can be critical.

- Biotic and abiotic factors affect the organisms in an ecosystem. Biotic factors may include things like predation, disease, competition, parasitism, consumption, and symbiosis. And certainly abiotic factors, like the weather, can also impact living things. The interplay of all the biotic and abiotic factors in an ecosystem determines the carrying capacity of that ecosystem for any particular species.

The Water Molecule Floating in H2O is made somewhat easier due to the density of water. Most organisms have bodies that are at least 90% water, which means that at least 90% of their body weight will be offset by the weight of the water around them. It's that last 10% that is critical. Organisms that live on the bottom of a body of water are called benthic organisms.

- Clean water is essential to life itself. Adverse changes to the water quality of one stream can impact all the bodies of water downstream – rivers, lakes, or even the ocean. When water quality degrades, changes to plant, invertebrate, and fish communities may occur and affect the entire food chain.quatic macroinvertebrates live in water for at least part of their life cycle. They include insects, worms, snails, mussels, leeches, and crayfish. For the purpose of assessing water quality, sampling is focused on benthic macroinvertebrates, those organisms that live at the stream bottom.

Effects: the living environment Effects: the living environment: The living environment describes all the living things that interact with an organism, either directly or indirectly. The living (or biotic) factors influence the life of an organism and includes factors such as the availability of food, the presence of predators or competitors and disease organisms. The relationship between organisms is sometimes beneficial but at other times it is detrimental (damaging).
