In Yann Martel’s Life of Pi‚ symbolism such as pi’s name‚ the colour orange and the algae island‚ are used throughout the novel to provide Pi with protection to help him either survive or overcome his emotional pain. The mathematical pi is undefined‚ infinite and unable to be understood‚ just like Piscine Patel. Piscine’s nickname is Pi

eutrophication process results in the depletion of dissolved oxygen in the water provoking animals and plants dyeing because of the lack of dissolved oxygen. Eutrophication can produce problems such as bad taste and odorous as well as green scum algae in water bodies. Also‚ the growth of rooted plants may increase‚ which lead to the decrease on the amount of oxygen in the deepest waters of a lake for example. In extreme case eutrophication may lead to the death of all forms of life in a water body

Diatom is part of the stramenopiles clade‚ which is considered to be plant-like autotrophs that are often called algae. These autotrophs are mainly photosynthetic using chlorophylls a‚ chlorophylls c and xanthophyll to undergo photosynthesis to convert energy from the sun. Some species of Diatom are colorless‚ but those that do have color get it from various pigments. Diatom have two halves of their cell wall making up what’s called a silica cell wall. The soft part of the cell wall decomposes‚ but

Spirulina is an amazing super food that many people have been using over the past decade to get more protein in their diets. Put simply‚ spirulina is a supplement taken from the blue-green algae that grows in water that is highly alkaline. It can be found at many health food stores and is available as a powder‚ tablets‚ and even dried and flattened wafers. In addition to protein‚ spirulina also contains many other essential nutrients in extremely concentrated quantities. Some of these include iron

a vital and important role in keeping the reef healthy and flourishing. In the reef ecosystem the algae which lives on the corals are the producers‚ they create energy through photosynthesis‚ the herbivorous fish in turn eat the plant life‚ and the carnivorous fish eat the herbivorous fish keeping the reef balanced. “When harvested sustainably‚ live fish from a healthy

Example: rocky seashore – Algae of the sub tidal zone: This zone is the least stressful zone‚ and it lies below the normal watermark. The most common algae in this zone are the large brown kelps‚ which are strongly attached to rocks and rocky formations. They have long fronds that float‚ whilst some have air filled bladders that help them float‚ and that are photosynthetic‚ and they form the canopy of a marine forest. Organisms of the intertidal zone: Brown algae Hormosira banksia is the most

Therefore Coral reefs live in a relationship with the millions of microscopic algae called zooxanthellae. Coral reef provides nutrients and protection to zooxanthellae. Algae helps coral to grow faster by providing it with photosynthesis using the sunlight to convert these into more complex nutrients like sugar‚ which the polyps then eat too. Also the zooxanthellae gives the coral it colours‚ the coral tissues are clear and these algae come in all kinds of different colours‚ which is why coral reefs are normally

WATER POLLUTION IN CHINA River like blood in Roxian‚ Guangxi About one third of the industrial waste water and more than 90 percent of household sewage in China is released into rivers and lakes without being treated. Nearly 80 percent of China’s cities (278 of them) have no sewage treatment facilities and few have plans to build any and underground water supplies in 90 percent of the cites are contaminated. Water shortages and water pollution in China are such a problem that the World Bank
