Brown algae Essays

do contain mitochondria where cellular respiration occurs after the chemical reaction, photosynthesis, is complete. This allows globby to then yield CO2, H2O, and ATP that can help grow the shell, while the products of globby can also provide the algae cells with the essential ingredient, CO2. This permits the photosymbionts to continue to perform photosynthesis and for globby to obtain a vital food source through the photosymbionts performing photosynthesis located within it, creating a beneficial

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

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

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

use their muscular foot with its suction power to move, cling and stay tight with the substrate surfaces. Feeding habits: In nature, abalone eats marine algae with a particular preference to large brown algae such as giant kelp and other kelp species. While juvenile abalone grazes for algae, diatoms and bacterial films, adults rely on drift algae, and if food becomes scares, they move after their food. Under farming conditions where most of abalones are produced, the macroalgae are the main abalone

and fresh water habitats in Florida and coastal regions. Manatees first appeared in Florida about 15 million years ago. Manatees are very large marine mammals that are related to elephants. ‘’They are grayish brown in color and have thick, wrinkled skin on which there is often a growth of algae. Their front flippers help them steer, or sometimes crawl, through shallow water.’’ Even though it seems like Manatees have small eyes and no outer ear, manatees can see and hear very well. Manatees play an

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

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 and translucent teeth. The size of angler fishes are normally smaller and often less than a foot but there still some of them can be quite long, reaching 1 meter

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, high-density foods

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

Abstract Belize’s coral reef is a beautiful ecosystem, comprising of approximately 500 species of fish. It is one of the largest reefs in the world, second to Australia’s Great Barrier Reef. The reef serves as a natural break from water waves. In 1998, two seemingly unrelated events occurred that destroyed Belize’s coral reef. In November, Hurricane Mitch, blew in and tore away part of the reef leaving behind some corals, known as the “standing dead”. After that, El Niño came along and brought warmer

Introduction: These bright colored systems are important in our ecosystem for many reasons. Often called the rainforests of the ocean, coral reefs are a vital source for this planet. They provide a buffer, protecting our precious coasts from catastrophic storms, horrendous waves, and damaging floods. Coral reefs provide and form an amazing barrier to protect our sandy or rocky shorelines from everything bad in the questionable ocean. Not only do they protect us humans from flooding, erosion, and

Green Sea turtles are also called Pacific Green turtles and Black Sea Turtles. Its scientific name is Chelonia mydas. It belongs to the family ‘Cheloniidae’ and genus ‘Chelonia’. This species is found in the seas of tropical and subtropical areas. It has two diverse populations in Atlantic Ocean and Pacific Ocean. Green sea turtles have flattened bodies which are covered by big carapace. They have two large flippers. Their colors are light but the species that are living in the eastern Pacific

AP Environmental Science: Chapter 5 1. Explain how southern sea otters act as a keystone species in kelp beds. The otters help to keep sea urchins and other kelp-eating species from depleting highly productive and rapidly growing kelp forests, which provide habitats for a number of species in offshore coastal waters. Without southern sea otters, sea urchins would probably destroy the kelp forests and much of the rich biodiversity associated with them. Explain why we should care about protecting

nutrient rich pollution which have contaminated these coral sanctuaries. This contamination has lead to great loss of coral coverage. As well as this, nutrient rich waters have also resulted in stimulating the growth of many bioeroders such as fleshy algae, which consistently attack the structure of the reef (Hallock. P, Schlager. W,
