Ranging from microscopic‚ single-celled organisms to large seaweeds‚ algae are simple plants that form the base of food webs. Sometimes‚ however‚ their roles are much more sinister. A small percentage of algal species produce toxins that can kill fish‚ mammals‚ and birds‚ and may cause human illness. Other algae are nontoxic‚ but clog the gills of fish and invertebrates or smother corals and submerged aquatic vegetation. Others discolour water‚ form huge‚ smelly piles on beaches‚ or cause drinking

Experiment Number: 5 Date: December 8‚2011. Aim: To assess and analyze man’s impact on the small coralline cay- Lime cay. Apparatus: boat Introduction: Lime cay is a small coralline cay that is mostly used by humans for their personal entertainment. By visiting this cay‚ man has had detrimental effects on the environment. In the earlier times‚ man’s impact was not so prevalent‚ however‚ overtime it has increased as agricultural practices and technology has been introduced. The effects can rise

cultures that the company trying to adapt and implemented in the company regulations‚ Monsanto Company’s regulation had become financial burden to many farmers‚ in patent issue for instance. Farmers who buy seeds from Monsanto could not saved for future plant. This is due to unethical practice done by Monsanto‚ whereby farmers claim that the company forced them to buy new seeds after a year which puts an undue financial burden on them and give Monsanto too much power.

Aquatic pollution is a worldwide problem that occurs every day in all bodies of water. Adedeji and Adetunji (2011) refer to aquatic pollution as an addition of hazardous substances‚ called pollutants‚ to these bodies of water. These pollutants are harmful to humans‚ but more importantly‚ they are extremely harmful to marine life due to the contamination of their habitats. Unfortunately‚ this occurrence is not uncommon‚ and it is mainly the result of human activities. Most pollution is derived from

abiotic factors‚ which are the nonliving things in the eco-column‚ include the water used in the aquatic habitat‚ soil used in the decomposition habitat‚ air‚ and some rocks that were used in the decomposition habitat. The biotic factors‚ which are the living things in the eco-column‚ include the grass and/or the terrestrial plants used in the terrestrial habitat‚ the fish (guppies) used in the aquatic habitat‚ and finally the worms that were used to feed the fishes once. Those are all the factors

cause water pollution and damage to coral and other aquatic life. Destructive fishing techniques involve the use of dynamite or cyanide; trawling in coral-rich ecosystems; bottom trawls that are dragged along the ocean floor‚ also disrupt and damage critical habitats. DUMPING Coastal communities have long used oceans as dumping grounds for all types of waste. Some of this pollution‚ such as toxins from heavy industry have directly killed plants and animals that are part of the marine ecosystem. Other

This study was conducted within the province of Laguna last February 23‚ 2013 to make the students become more conscious on what is truly happening in their surroundings and to be able to let them know the relevance of the topics discussed in the lecture. Objectives: 1. Describe the interaction of terrestrial with aquatic ecosystems;
