Phelisha Colebrooke Dr. Byrd EN 125 7 February‚ 2014 My Life‚ My Story Many people in today’s society think just because I am a young lady I have an easy fun filled life. Well‚ that is not true. Life has many ups and downs but it is up to us whether we want it to be a successful one or not. Life is filled with obstacles for us to overcome no matter how tragic. Back in 2009‚ the most unexpected tragedy I thought that would never happen occurred. My grandfather died in September and my grandmother

They are nurseries and homes for sea life‚ like shrimp‚ zoo plankton‚ and other fish. As the temperature rises it also increases the heat of the ocean itself. Carbon dioxide is trapped in the water and this raises the ph level of the sea. Increased acidity can harm fish that predators rely on for a balanced and or

Global warming has become the big issue for environmental reasons. Corporations and individuals around the world are discussing the dangers of global warming. They are trying to find out ways to fix this problem and come up with a good solution. Global warming has become the most difficult problem that is facing

The Cretaceous Period and the Aftermath Imagine a great‚ thickly muscled dinosaur. Got it? See those serrated teeth? And the great yellow eye that is pondering whether you are food or foe? Now‚ imagine something that can kill this beast and all of its kind. This “something” is called the Cretaceous Tertiary Extinction event‚ and it occurred 65.5 million years ago‚ and killed all the dinosaurs‚ and affected the process of evolution forever afterward. The Cretaceous

Microorganisms like plankton and algae are especially true‚ this because aquatic environments can bring contact with the organisms more. * Invertebrates: Terrestrial invertebrates like molluscs and earthworms are less affected by DDT.

------------------------------------------------- Balance of Nature The balance of nature is a theory that says that ecological systems are usually in a stable equilibrium (homeostasis)‚ which is to say that a small change in some particular parameter (the size of a particular population‚ for example) will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system. It may apply where populations depend on each other‚

Mantis shrimp do not have a large part to play in their marine eco-system. They keep the crab and snail populations down lower than if there are no mantis shrimps. The main role they play in the eco-system is when they are zoo plankton floating around the oceans feeding fish‚ whales and other wild life. Human activities have had a small impact on the mantis shrimps population. Although the threat of humans isn ’t enough for us to be a real threat to their survival. The main reason

harmful elements like mercury and aluminum to be leached from the soil and rocks and it is then carried into the lakes where aquatic life may be affected . The effects of acid rain also inhibit plant germination and reproduction. As the pH reaches 5.5‚ plankton‚ certain insects and crustaceans begin to die. At a pH of around 5.0‚ the fish population also begins to die. All living organisms are interdependent on each other. Source:

On the contrary‚ studies have shown that a more acidic environment has a negative effect on calcifying species‚ such as oysters‚ clams‚ sea urchins‚ corals‚ calcareous plankton and many more. When shelled organisms are at risk‚ the entire food web is also at risk. Currently‚ over a billion people worldwide rely on food from the ocean as their primary source of protein. Many jobs and economies throughout the world depend

Anthropocene What and Why? The Anthropocene is a term widely used since Paul Crutzen and Eugene Stoermer in 2000 to indicate the present time interval‚ in which many geologically significant conditions and processes are being altered by human activities. These changes include; erosion and sediment transport associated with anthropogenic processes that are objects or materials that are derived from human activities‚ as opposed to those occurring in natural environments without human influences.
