Chapter 52 - Abiotic Factors
In regular Biology you learned the difference between biotic and abiotic factors. Biotic are living factors and abiotic are non-living factors. In Chapter 52 page 1154, the book explains the most common types of abiotic factors. They are Temperature, Water, Salinity, Sunlight, and Rocks and Soil. For your discussion, I want you to pick one of these abiotic factors and explain its importance to the environment. No more than 4 posts on a specific one. Also, take time to read what your classmates find out about a different one from yours. This assignment is due Tuesday, March 8th.
~Sunlight~
ReplyDeleteSunlight is important to the environment in how it provides most of the ecosystem with energy. Too little or too much can effect the growth and deveolpment of plants and animals. Too little slows or stops growth. And too much can damage DNA and proteins.
*Temperature*
ReplyDeleteTemperature is a very important abiotic factor. It determines how an organism lives and how everything is done. If the temperature isnt a certain degree many things could die. few organisms can maintain an active metabolism at very high and low temperatures. Temperature effects everything around us and determines what we do and the way we do it.
-Salinity-
ReplyDeleteThe salt concentration of water in the environment affects the water balance of organisms every day through osmosis. Many animals that live in water are limited to either salt water or fresh water because of osmoregulation. Osmoregulation is the regulation of solute concentrations and water balance by a cell or organism. So, as you can see without salinity our animals would not have the proper water to live in and our lives would never be the same.
Sunlight
ReplyDeleteSunlight is ultimately the source of energy for all of the organisms on Earth. Without the sun plants would not be able to perform photosynthesis, this would in the end kill the plant. Since plants are at the bottom of the food chain, without them it would kill everything above.
WATER!
ReplyDeleteWater is very important for all living things to live and function properly. Without water animals would die, trees would die, life would cease to exist without water. Every process on earth requires water in some way. Without it sunlight wouldnt matter, soil wouldnt matter, temperature or salinity wouldnt matter, because nothing on earth would be alive.
Soil:
ReplyDeleteThe composition and pH of soil and rock can determine the distribution of plants and the animals that feed on those plants. If the pH is extremely acidic or basic it can limit distribution. The solubility of nutrients and minerals also affects biotic factors.
SOIL-
ReplyDeleteSoil is one of the leading causes to different terrestrial ecosystems. One might ask how soil can affect where an organisms habitat is. The question is simple when thought through. Soil can be the deciding factor into which types of vegetation grows in an area. Naturally some plants will thrive in certain types of soil, while others will not. This leads to diversity in vegetation throughout a region. Diversity in vegetation will result in a diversity of wildlife due to different plants in which some animals can consume, while others can not. This affects a regions diversity of wildlife as a whole. These are all affects throughout land, but what about water? Soil along the bottom of a stream or river can also affect water chemistry which in turn results in yet again diversity in wildlife. So as you can see soil is more than just a bases for plant growth. It can persuade a whole regions wildlife.
SUNLIGHT :)
ReplyDeleteSunlight fuels everything. Sunlight absorbed by photosynthetic organisms provides the energy that drives most ecosystems. Too much or too little sunlight can hurt any ecosystem. Too little sunlight can limit the distribution of photosynthetic species. Too much sunlight can also limit the survival of organisms.
Water :)
ReplyDeleteWater is essential to daily life. Without water we would all die. Water is the universal solvent and essential to every aspect of life!
Sunlight-
ReplyDeleteSunlight is one of the most nessesary and important factors to sustain life on Earth. Without sunlight to absorb plants would not be abe to photosynthesize and therefore make no food. And if plants are not able to make food they would simply die. If the plants die then most other organisms that feed on autotroughs would eventually die out. That is why i think sunlight is an important factor of sustaining life on Earth.
*ROCKS*
ReplyDeleteVarious properties of rocks determine the availability of plants, thus affecting the animals that feed on the plants. Such properties are: pH, mineral composition, and physical structure. In addition to determining conditions of plants, rocks' properties of acidity and basicity can determine the distribution of organisms in their environment. In the larger scheme of things, rocks are used for building and manufacturing, fuel, and even jewelry cultivation!
Salinity
ReplyDeleteThe salt concentration of water in the environment affects the water balance of organisms through osmosis. Osmosis is the movement of water. In an organism’s body, if there is an increased amount of salt on the outside of the organism’s cells, through the process of osmosis water will leave the cell and cause the cell to shrivel making it impossible for that cell to survive. Most aquatic organisms are restricted to either freshwater or saltwater habitats by their limited ability to osmoregulate. In other words, aquatic organisms have a hard time controlling solute concentrations and balancing water gains and losses. Although many terrestrial organisms can excrete excess salts from specialized glands or in feces, salt flats and other high-salinity habitats typically have few species of plants or animals.

Temperature-
ReplyDeleteAs with the other abiotic factors, temperature affects organism distribution and their way of life. In extremely cold areas, only organisms built for those conditions can survive there but they still have to take extra "precautions" to stay healthy. A drastic change in temperature can have a detrimental impact on any organism.
-Water-
ReplyDeleteWater is essential for all living things. I believe that it is the most important because without it all organisms would die. Every living thing has to have water to grow and perform different functions. :)
-water-
ReplyDeleteWater holds its roots in all environments. All living organisms require water to live and provide food for other organisms. Without a source of some sort of water a habitat will cease to exist.
*Sunlight*
ReplyDeleteAlong with water sunlight in my opinion is one of the major factors in the enviorment. Without sunlight for instance there would be too much water for the plants to handle and it would result in the death of all plant life. This is because the plants would be overwatered. Also, without sunlight how would plants and trees recieve their food? The process in which plant life recieve their food is called photosynthesis. This would not be able to occur without the advantage of the sun! :)
