May 2005 Garden landscapes Newbury, UK. After leaving school I worked as a labourer for a garden landscaping firm. Tasks included maintaining gardens to constructing bird aviaries. Mar 2007 38 Engr Regt Op TELIC 9. Attached to a field squadron as a Plant Operator, I carried out routine maintenance and servicing on plant equipment.

M3 M3: Make and support valid decisions relating to the specification of materials for a tutor provided application Introduction By using the materials identified in P6 I can decide on which material is best suited for a foundation, building frame, guttering, external cladding of walls and wall insulation by looking at each materials properties and performance. This will help decide on which material is best suited for each component of the building as we will be able to find which material is the strongest and long-lasting for the foundation and which is best at stopping heat transfer for the wall insulation. For a construction project to be successful the right material needs to be used for each component in the building to ensure that the

All organisms need oxygen to survive and when their is not enough oxygen, it leaves plants and animals to die. The area of water where there is a low count of oxygen are often called a dead zones. Also, an increase of the pH level in the water can be created because of algae blooms. The toxic killing algae can make humans sick. For the aquatic animals, these toxins attack mainly the organisms liver and nervous system (Nitrogen and

M3 Task: Explain how an awareness of learning styles can aid your development In this task I will be explaining how an awareness of learning styles can aid your development in being an effective learner. There are different types of learning styles that different people have and I’ll be explaining how these aid the learner to progress. For example there are 3 main learning styles these are Visual, Auditory and Kinaesthetic.

1 Ecosystem Dynamics and Trophic Energy Marc Mueseler BIO111 Biology Laboratory Abstract: The purpose of this experiment is to study different ecosystems and observe the change in the number of organisms at each trophic level as well as the energy transfer to each of these levels. It was observed that the number of organisms dropped off significantly from level to level as the energy transfer efficiency was approximately 10% at each heterotrophic level. Each ecosystem was only able to support about four levels before all of the energy in the system was essentially depleted. The number of organisms in each ecosystem was dependent upon the number of producers available to make their own energy thereby making that energy available to

In session 13, the young adults will learn the basic skills on how to resolve disagreements with their friends and romantic partners that are common among young adults. The young adults are expected to do each step of how to respond and bring up disagreements so that they can effectively resolve conflict with others. In this session, the therapist will help the young adults to understand that disagreements and disputes, especially those that are occasional are common and it should not be a reason to end their relationship and friendship. Young adults will also learn that there are two types of position that they might be in in a disagreement, which is either someone is upset with them or they are upset with someone. If someone upset with them,

Off shore dredging of sand and shingle in adjacent areas increases erosion in other areas and significantly affects the ecosystem in the dredging area. Large storms easily degrade beach replenishment inputs, thus increasing costs. £20.000 per cubic meter Managed retreat In areas where Managed retreat is permitted, it retains the natural balance of the coastal system. The eroded material promotes the development of beaches and salt marshes in specified areas.

However, there are a number of advantages to bioremediation, which may be employed in areas which cannot be reached easily without excavation. The foundation of bioremediation has been the natural ability of microorganisms to degrade organic compounds. Bioremediation is not a panacea but rather a natural process alternative to such methods as incineration, catalytic destruction, the use of adsorbents, and the physical removal and subsequent destruction of pollutants. The cost of moving and incinerating pollutants is at least ten times that of in situ biological

Matthew Blanch Mr.DeJong Science 11,7,2017 Eutrophication The eutrophication of these muskrats in lakes is when fertilizer goes into the lakes and because light reflects off the lake no sunlight hits the seaweed and the seaweed dies then the nitrogen from the seaweed goes up onto the surface of the water and turns it into a messy green slob. Killing the muskrats.

Lake Erie Hurry, Lake Erie needs your help! In 1960 there was severe pollution in Lake Erie and now, 3 years later, the pollution is back and has created an extensive amount of algae. In the 1960s Lake Erie was extremely polluted. “As a result of these pollutants, Lake Erie contained increased levels of phosphorus and nitrogen, which contributed to eutrophication - a process that encourages the development of algal blooms.” (Michael Rotman).

One of the main distributors of pollution is sewage. Sewage and other polluting substances flow into the world's rivers and drainage pipes until all of the substances dump out into the ocean. In addition to sewage, other chemicals finds its way to the oceans, which leads to the reduction of oxygen being released into the atmosphere. With this in place, the waters become murky and filled with substances that can harm marine life.

Water Pollution is a huge environmental problem that has serious effects on marine habitats, animals, and water quality. BP1: The world's marine habitat has been getting worse because of how bad the pollution has gotten. “ Over 80% of marine pollution comes from land based activities “ (source 5 ). This quote explains how most of the water pollution is caused by human activity. “ Plastic litter does not degrade, can be expected to last in the oceans for hundreds of years “ ( source 6 ).

There is an idea called Seawer, and it will strain and filter ocean water. The invention could catch bigger trash and also can prevent small plastic particles, such as microbeads, from entering the water. The system could do much more to benefit people too. It is able to, “. . . produce hydroelectric power and purify seawater for drinking and irrigation,” (Samoray).

Phosphorus is then transferred from plants to other living organisms via the food chain. The phosphorous is returned to the soil

ECOSYSTEMS “An ecosystem includes all of the living things (plants, animals and organisms) in a given area, interacting with each other, and also with their non-living environments (weather, earth, sun, soil, climate, atmosphere).”
