Activity 2.3- Biosphere and Interconnections

 




Energy is all around us and it is the reason why there is life on the planet. Three types of energy are Electromagnetic, Kinetic, and Potential energy. From there energy breaks down into many subcategories. The first and second Law of Thermodynamics are the ones that impact planet earth the most. The first law states “Energy can undergo transformations among its various states, but it is never created or destroyed; therefore, the energy content of the universe remains constant.” (Freedman) This means the amount of energy in the universe should remain the same. Energy can change forms, but it will not create any more energy. The second Law of Thermodynamics states “transformations of energy can occur spontaneously only under conditions in which there is an increase in the entropy of the universe.” (Freedman) This means when energy is transferred it cannot go back to the original form unless the environment changes.

The variety of lifeforms on the planet allows organisms to thrive. Biodiversity can help keep a proper cycle of an area. Genetic variations can benefit a species by giving mutations for a specific way to live. With so many organisms in the world there needs to be a way to sort them out. This is where classification comes into play.

Biomes cover the entire planet. A biome is characterized by their lifeforms and their dominate organisms. In water they are classified by animals while on land they are classified by plants. Canada is split into 15 terrestrial eco zones. But these ecozone not only affect Canada but all ecozones and biomes on North America.

Activity 2.3.1 Ranchers, Anglers, and Beavers

  Six-Point Critical Analysis of Current Event     1. Exploratory                                      Relative to a comparable site with hot season grazing and no beaver, the study shows that streamside vegetation can be 10–40% more productive where conservation-oriented grazing approaches are applied, and beaver are at work. ( Fesenmyer ) This means there is more food for grazing animals and leads to more diverse wildlife in the area. The What’s more, the study shows to get comparable gains in vegetation at sites with hot season grazing and without beaver, you would have to move a site 800 feet up in elevation or increase annual precipitation by almost 10 inches, nearly doubling the average annual precipitation at some sites. ( Fesenmyer ) study also demonstrates that conservation-...

Activity 3.3.3 – My Plastic Use

Image
 I did not do a whole day but the first five minutes of waking up From the highest mountain to the lowest point of the ocean plastics can be found everywhere. It is impossible to go a day without feeling the impact plastics have had on the planet. One issue that we are starting to realize is what happens when these plastics start to breakdown. We have been engrained that if we do not see it then it does not exist but now we are learning that is not true. As plastics start to break down microscopic particles are being released in the environment. And since plastics are everywhere this has become a major issue. When talking about these microscopic pieces of plastic we call them microplastics. Microplastics, which are plastic particles or fibers smaller than 5 millimeters (mm) in size. (Haab) Microplastics are mostly derived from petroleum which is an additive used in a variety items. Because microplastics are derived from petroleum, they are not biodegradable, which means that they...
