How Abiotic Factors Present In an Ecosystem Affect the Organisms

Extracts from this document...

Introduction

HOW ABIOTIC FACTORS PRESENT IN AN ECOSYSTEM AFFECT THE ORGANISMS Mustafa Ganijee Abiotic factors are physical factors (non-living) factors that affect the distribution of organisms in their habitats. The abundance and distribution of a species is determined by whether levels of one or more physical and chemical factors go above, or fall below, the levels tolerated by the species. The figure below shows how the performance of any species is affected by an abiotic factor. ...read more.

Middle

the determination of sex in alligator and crocodile eggs. Most living organisms have an optimum temperature range within which they can survive (optimum rate of reaction and enzyme activity). The main source of heat is the sun via radiation. This factor will be affected by the habitat's latitude, the season of the year, time of the day and its aspect. Very low temperatures cause damage to cells due to formation of ice crystals and very high temperatures denature enzymes. ...read more.

Conclusion

In aquatic habitats the depth of penetration of light affects the distribution of organisms. The main importance of light to animals is its photoperiod. The duration of light determines the activity of some animals. Wind Wind affects organisms through its interaction with other physical factors. It affects the growth of vegetation in coastal areas as prevailing winds determine rainfall. Wind speeds up the process of evapotranspiration that may be harmful to the organisms present or cause rainfall. Some reproductive mechanisms of plants are dependant on dispersal by wind, therefore, it may be essential to them to maintain continuity. ...read more.

    * Mammalian Physiology and Behaviour - Used for background information on bile and digestion of fats. The same can be said about the information I collected from this book, as it to is accurate and reliable. This is because again it is a scientific book checked by many scientist to

  1. An investigation into the distribution of adult and juvenile limpets on a rocky shoreline.

    structure to the limpet's contraction, the orangelles within the cytoplasm of the cells may not function properly therefore not producing the ATP or the enzymes necessary for survival and so the limpet may die. The limpet also has a strong muscular foot, which allows it to attach tightly to the rock and limit evaporation.

  2. The Effects of Abiotic & Biotic Features on the Distribution of Plants and Animals ...

    Wind speeds also affect the rate of transpiration, and the likelihood of the exposed side of the tree freezing. These three affects could mean that a certain plant could no longer survive in the area, so they would not be as widely distributed.

  1. Investigating how prolonged exposure to its optimum temperature affects the respiration of yeast.

    For example, in the pilot method keeping five minutes as the amount of time for measuring each temperature and the respiration the yeast gives off during this time. * Amount of glucose used. This will ensure that the yeast receives the same amount of glucose (a necessity for respiration), and is available to be used.

  2. Weed study. Dandelions - descrption and characteristics. Investigation to dandelion distribution.

    Therefore I will implement my experiment making sure that I have covered everything that I did not include in my A/S level coursework. The aim was to actually to investigate the abundance of Dandelions (Taraxacum officinale.), in two different sites.

  1. out how different concentrations of the enzyme pectinase affect the degradation of the substrate ...

    An increased rate of reaction would result in more pectin being catalysed in a given time, so leading to an increased rate of juice flow. Although highly unlikely in this experiment, significant increases in temperature would cause the atoms within the pectinase molecules to vibrate.

  2. The Homeostatic Mechanisms

    As the persons pores are closed, heat build ups in the person?s body, causing their temperature to rise. The hypothalamus will detect an alteration in the blood temperature, and respond to this by bringing down the heat, acting as a thermostat, by instructing the pores to open, so that the
