The members of a pod hunt together, attacking even very large prey and then sharing it. The pod members always protect the young, the sick and the injured. Orcas grow to be about 27-33 feet long, and weigh more than 8,000-12,000 pounds. The male orca is larger than the female. They are the largest member of the dolphin family.
(Chesapeake Bay.net) With that being said, it isn’t a surprise that the Chesapeake Bay literally translates to “great shellfish bay”, but it would not hold this title for long. By the early 20th century nearly three-quarters of the bay’s oyster reef population have been over-harvested using dredging techniques. (Oysters in the Chesapeake) Today, overharvesting has led the remaining oyster population in the bay to be only one percent of its historical amount and now the remaining population faces problems with pollution, diseases, reproduction problems, and continued harvesting. The Chesapeake Bay is a vast system of waterways with an even vaster watershed that is 64,000 square miles with an estimated 17 million people living in this area. ( Chesapeake Bay Program)
MARINE BIOMES Introduction The marine biomes, which are saltwater environment, are the biggest biome in the world. It covers about 71% of the earth. Marine biomes form a category of aquatic biome uniting estuaries, oceans, seas and coral reefs. Did you know…? The marine biome is located by the ocean or sea in lots of places.
Evaluate the relative importance of global and local threats to one named global ecosystem (15 mark) One named global ecosystem is the coral reef. In order for an ecosystem to be a coral reef they would need to be in certain conditions; it usually is where the temperature is around 24 degrees and be in water less than 25m depth. The Coral reef has many global and local threats. The coral reefs are homes to over 25% of known sea creatures and are an invaluable service for the local population as a source of food and income. One major threat is that coral reefs are under huge stress due to the impact that human activities are having and in fact already 1/5 of the world’s coral reefs are so damaged that they are beyond repair.
Biology Excursion Question Using data collected on field trip and two named animals, explain the relationship between the distribution and abundance of these two organisms and the abiotic features of the rock platform. There is a close relationship between the abundance and the distribution of organisms living amongst the long reef platform. Abiotic features such as temperature range, salinity, Ph. levels, turbidity, water availability effect the distribution and abundance of aquatic sea creatures living in the area. Some of the organisms such as Tesseropora Roseas (Barnacles) and Knobbly Winks have different adaptations, which allow them to survive in these harsh conditions.
Sometimes they get overly excited going from one pool to another and slip on the coral reef, which can put a damper on all the fun. When this happens they usually take advantage of one of the many parks located in the area. The parks allow them to play with both, American and Japanese children. All these activities will leave an impression on them that will last a lifetime. The actual seawall is what makes this area unique.
Giant Kelp: An Underwater Forest What are three take home messages from this information presented? Giant kelp (Macrocystis Pyrifera) is the fastest growing plant in the world. A fond (labeled in the sketch) can grow up to two feet per day and can reach lengths of 200 feet+. Each kelp plant is anchored to a rock, as they do not have roots. A cluster of strands attaché themselves to a rock, called a holdfast.
Despite this, there are emerging findings about what climate change might mean for the UK. Agriculture, housing, flood risk, biodiversity, energy supply and demand, water availability and health are all likely to be affected. Even with strong international action on mitigation to stabilise global temperatures at around 2°C, past and present emissions mean that the climate in the UK will continue to change and the UK will need to respond to this. The Adaptation Sub-Committee provides independent advice to the UK Government on what action the UK should take to prepare current and future climate change impacts. ENGLAND ENGLAND England is the most populous country in the United Kingdom.
This species has diverse color variations. The base color is usually brown to white and the tentacles may or may not have magenta, purple, or green tips on its long tapering tentacles. The tentacles may occasionally develop a bubble-like appearance to them. It prefers to bury its base in the sand or into the crevice of a rock for protection. The Condy Anemone requires
This complex ecosystem is both an extraordinary geological and ecological feature of Florida and encompasses a historic, social, economic, and environmental significance. The IRL is a network of people, places, and natural resources that are inter-dependent upon each other. Unfortunately, the primary threat to this unique ecosystem comes from human population growth as well as coast-line developers. The storm water and sewage run-offs pose significant pollution problems to the ecosystems survival. Today, scientists, and resource managers are concerned about the future of the lagoon, including declines in quality of the water, loss of habitat, biological diversity, invasive species, diminishing fisheries, and the declining of the ecosystem’s health.
