Green algae Essays

colonial green algae? An example of filamentous green algae is the spirogyra. An example of unicellular green algae is the chlymodomonas and the colonial green algae example is volvox. How are green algae different from cyanobacteria? ` Cyanobacteria are photosynthetic bacteria while green algae are photosynthetic eukaryotes. Cyanobacteria do not have a nucleus or mitochondria while green algae do. They reproduce asexually while green algae reproduce both asexually and sexually. Green algae are symbiotic

simplest form of a trash littered beach that almost any resident of Florida can attest to or it can take the form of something much greater. This greater form of pollution is the massive outbreak of green algae that has occurred in Florida with one of the most recent back in July of this year. The algae outbreak is caused by “fertilizer sewage and manure pollution that the state has failed to properly regulate” as stated by Earthjustice spokeswoman Alisa Coe. This

Now the question presents itself; “why would anyone ever want to use algae as a fuel?” Algae is an extremely green fuel. Algae based fuel has a carbon neutral combustion meaning it isn’t bad for the environment. This means that if algae became one of the leading sources of fuel it wouldn’t pollute like gasoline or diesel. It is also a plant, meaning when it grows it converts CO2 into oxygen, meaning it takes pollutants and turns them into breathable air. It also doesn’t have to be grown in a stereotypical

because both are key elements in growth in lakes. The Virtual lake includes these five simulated species; green algae, cyanobacteria, bosmina, daphnia, and trout. There are two types of phytoplankton in the lake model, green algae and cyanobacteria. Green algae are a very diverse group that are photosynthetic, aquatic, plant like organisms that have a very simple reproductive structure. Green algae growth is a healthy and natural part of a lake’s ecosystem but the addition of nitrogen and phosphorus

The Island Biogeography theory and species richness in different tidal pools on St Lucia coast lines By: Daniela Maia student number: 201406936 Introduction Islands are most commonly known as landmasses that are surrounded by a body of water, in this case the ocean is the body of water. Islands, however, are also isolated areas within another area that bear different species that are rare as well as unique in comparison to the surrounding environment (habitat within a habitat) says

gastropod mollusk, abalones are characterized by one shell.Several abalone species have been identified of present or potential economic value whether for capture fishery, stock enhancement or aquaculture. These include red abalone (Haliotis rufescens), green abalone (Haliotis fulgens), Japanese abalone (Haliotis discus hannai) and Omani abalone (Haliotis mariae). Abalone has a worldwide distribution; with some exceptions, they occur along the coastal waters of every continent. According to FAO statistics

species is native to the coasts of Chile and Peru and is considered among the key benthic herbivores in Chilean coastal waters. It is harvested commercially by fishermen and is considered an ingredient in Chilean cuisine. It is also known as “common green sea urchin” and its local name in Chile is “Erizo rojo” which means “red urchin”. They can grow up to 100 mm in diameter or more. It takes eight years for Chilean sea urchins to reach commercial size. The industrial catches and over-exploitation of

bleaching is when the animals that build the coral shed the algae that give them their color and is necessary for survival. Coral bleaching is suspected to happen by two different ways. The first is due to warmer water. The coral needs to be in certain temperature in order to maintain its life. The second way is due to pollution. This could mean over exposure

Introduction In order for a coral reef to be productive and healthy, the water quality in the ocean should be maintained. Water quality not only affects coral reefs, but the other organisms that live on it and are involved with the natural food chain. Some of the factors that can influence water quality are nutrients, temperature, salinity, dissolved oxygen, turbidity, light, and chlorophyll present. Water is essential to every living organism because it helps with respiration, maintaining body

Effects of Red Tides on Ecosystems Background Info: Harmful algal blooms, or more commonly known as red tides, occur when a dinoflagellate colony grows out of proportion. Dinoflagellates are a type of algae and protist responsible for releasing a chemical that acts as a neurotoxin (called brevetoxins) in many organisms. This results in neurological effects in animals, birds, and other marine life. Red tides are not considered a new phenomenon, as they were first documented in the 1700s in the Gulf

threatened by climate change, pollution, and overfishing. All in which are man made influences that affect the ocean greatly. It is predicted that by the year 2050 90% of the coral reefs on earth will be dead or threatened. Not only that but soil erosion, algae growth from fertilizer runoff, increased UV exposure, and damage from fishing and diving are just adding to the problem. However, the

depths of about 750 meters. They can weigh up to 44 pounds and reach a length of about 25 inches, however they are typically around 2 feet long and weigh 3 pounds. The American lobster’s preferable habitat is on rocky surfaces covered with algae, because algae attract animals that the lobsters prey on. This habitat allows the lobster to hide within the cracks, where it can hide from predators in its environment such as flounder, cod, crabs and eels. They dig burrows under large stones to make usable

occur as a result of explosion of algae population such as dinoflagellates. The expansive population concentrates along the water column and cluster in one area of the ocean, this results in the change of color of the surface water. Red tides occur along coastal areas. Color: Red tides are not necessarily always red. The color may vary from deep shades of red to pink, orange, brown or even yellow. http://www.livescience.com/34461-red-tide.html Causes: Algae require sufficient nutrients. Warm

Angler fish is a bony fish from order of Lophiiformes. There are 18 families, 5 suborders and more than 200 species of anglerfish. Most angler fish around the world live in the bathypelagic zone of the Atlantic and Antarctic oceans. They can survive up from 1000m to 4000m below the surface, although some live in shallow waters too. (National Geographic) Most of the angler fish are generally dark grey to dark brown in colour, they have huge heads and enormous crescent-shaped mouths filled with sharp

sugar and salt. They tend to keep away from junk food, although an occasional treat now and then does not hurt them because they know how to control their cravings. Whole foods are natural foods like fresh apples and oranges, oatmeal, broccoli, leafy green salads, and brown rice. These are low-density foods that take up a lot of space in the stomach because of their high fiber content. As such, they satisfy hunger with just a few calories. They also contain a variety of nutrients. On the other hand,

Nearly 19.2 million Americans suffer from different specific phobias such as Aquaphobia. Aquaphobia is a social phobia that is defined as the persistent, unwarranted and irrational fear of water. Aquaphibians conjure up images of dying in the water, drowning, gasping for breath, or encountering eerie, unseen things such as snakes or sharks in the water. In the short story “The Isabel Fish” by Julie Orringer, one of the main characters Maddy has gained this phobia of water due to her car accident

When money is tight, you can always create your own baby food. Many baby foods found in stores are safe and convenient, however many contain a lot of sugar, water and starch. Homemade ones have lower amounts and are more natural. Babies don't need to consume solid foods until they are at 4-6 months old. Babies younger than 4-6 months old have not learned how to swallow. If they are given solid foods at any age before 4-6 months, they'll most likely push out the solid food due to the sucking reflex

I. INTRODUCTION The ocean is undoubtedly one of the most valuable resources known to humans. It is sometimes called as The Big Blue or The Great Provider. Ever since, people have taken advantage of the many benefits our ocean presents us with. It’s been used as a source of food and as a source of many minerals. However, unfortunately, what seemed to be impossible a hundred years ago is happening. Sadly, the existence of this great body of water is being threatened. Unfortunately, people

II. FACTORS CAUSING THE DECREASING OF OYSTER REEFS. Nowadays in many literature are represented the most important threats for oyster beds, as overharvest, development and pollution, changes in freshwater inflows, erosion from boats, diseases, invasive species, global change… (Coen et al. 2000; Seavey et al. 2011; Gregalis et al. 2008; Piazza et al. 2005). 1. Overharvest. Overharvest is one of the major threats to oysters worldwide (Beck et al 2011; Seavey et al. 2011). At the beginning of oyster
