only other fish species but disrupts other marine ecosystems. Another major problem is that there is too much pollution within the ocean. One type of pollution is toxic pollution. Toxic pollutants occurs when chemicals are dumped into the environment‚ or when natural chemicals build up to toxic levels. Toxic pollution can cause decreases in wildlife animal population‚ hurt the ecosystem‚ and threaten human health. But there are negative effects that are hard to ignore. Toxic pollution has been

Food chains‚ Food Webs and the Flow of Energy in Ecosystems Introduction An ecosystem can be defined as a more or less self-contained function unit in ecology consisting of all abiotic and biotic interactions in a specific area. Flow of energy within an ecosystem is a one-way process; Photosynthesis utilizes light (solar) energy to yield chemical energy that is passed on to organisms at significantly reduced amounts at each level of nutrition. This ‘inefficiency’ in energy transfer is the principal constrain

Investigating the Control Dynamics of an Algae-Brine Shrimp Ecosystem 113437768 Introduction The purpose of this lab is to investigate whether an ecosystem consisting of marine algae and brine shrimp are controlled by top-down or bottom-up mechanisms. The terms top-down and bottom-up in the context of ecology describe which trophic levels are enforcing population pressures on the others. Thus‚ the top-down mechanism of control holds that consumers are responsible for determining the abundance of

University of Bahrain College of science Department of biology The Effect of Salinity on Seed Germination 1) Abstract: Poor seeding growth can be the result of soil salinity. A study was done to examine the influence of NaCl salinity treatment on the germination and seeding grow of vigna radiata using different NaCl concentration 0 (control) ‚ 0.25 ‚ 0.5 ‚ 1.0 ‚ 1.75 . A graph was used to analyze the data obtained from the study. Important differences among the treatment

he Impact Of War and Weapons On Humans And The Environment Environmental Effects Of Weapons Chemical Weapons Approximately 19 million gallons of Agent Orange were used by the US military in southern Vietnam between 1962 and 1971. An aggressive herbicide which defoliates trees‚ it was used on a large scale in Vietnam’s jungles to enable US troops to spot Communist troops more easily. It eradicated around 15% of South Vietnam’s vegetation‚ and gave rise to serious health problems for the

Effects of earthquakes Shaking and ground rupture Shaking and ground rupture are the main effects created by earthquakes‚ principally resulting in more or less severe damage to buildings and other rigid structures. The severity of the local effects depends on the complex combination of the earthquake magnitude‚ the distance from the epicenter‚ and the local geological and geomorphological conditions‚ which may amplify or reduce wave propagation.[44] The ground-shaking is measured by ground acceleration

Effects of Deforestation The subject of deforestation and the effects that it has on the environment have been heavily debated for a long time; particularly over the last few years. Governments and large lumber companies see large profits in the mass deforestation of forests and state that their actions are having few‚ if any‚ harmful effects on the environment. Most people disagree with this and think that the environmental effects are devastating and will become irreversibly disastrous in the

the cause and effects of Deforestation The cutting down of forest or deforestation can affect us and have serious effects on our environment as well. A few effects of deforestation are soil erosion‚ disruption of the water cycle‚ and possible even global warming When forest areas are cleared‚ it results in exposing the soil to the sun. Which would make the soil very dry and eventually‚ infertile‚ due to nitrogen being lost. In addition‚ when there is rainfall‚ it washes away the nutrients
