The Energy Policy Act of 1992 (EPAct) defines alternative fuels as electricity‚ ethanol‚ natural gas‚ propane‚ methanol‚ hydrogen‚ and biodiesel (U.S. Department of Energy‚ What is the Energy Policy Act of 1992‚ para. 2). Gas prices all over the world have been elevated for years‚ giving drivers no other option than to pay the high costs of gasoline with more people driving vehicles that

Lichens Casey Stinnett ESC 1510 October 30‚ 2014 Introduction Lichens are a sybiotic association of fungus (mycobiont) and algae (Pediastrum boryanum . The fungus engulfs the algae‚ then supplies carbs‚ nitrogen‚ and vitamins while the algae photosynthesizes. This unusual relationship enables the lichen to grow in environments where neither fungus nor algae would normally be able to solely survive. They are found on every continent‚ ranging all the way from the freezing Arctic to the sweltering

Their necks can extend up to 8 inches. Mallard ducks like warm weather. They migrate for the winter so they can have source of food.Ducks dip their head down in the water for small fish and algae. This ducks roll in the eco system of the lake is to keep the lake clean by eating algae. They also help to keep the fish population stable by eating the fish for their food. The mallard lives in marshes‚ lakes‚ swamps‚ rivers‚ streams and ponds. They are mainly found in the north

other organisms to convert the light energy captured from the sun into chemical energy that can be used to fuel the organism’s activities. Photosynthesis occurs in plants‚ algae‚ and many species of bacteria‚ but not in archaea. Photosynthetic organisms are called photoautotrophs‚ since they can create their own food. In plants‚ algae‚ and cyanobacteria‚ photosynthesis uses carbon dioxide and water‚ releasing oxygen as a waste product. Photosynthesis is vital for all aerobic life on Earth. In addition

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

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
