2010 Introduction The intertidal zone‚ or littoral zone‚ is a slim perimeter along the shoreline. The intertidal zone is located between the highest and the lowest tides. Since the intertidal zone is located between the highest and the lowest tides it has many abiotic factors that make life challenging for the intertidal organisms‚ therefore the organisms must be well adapted to the intertial zone in order to survive. Intertidal organisms experience emmersion and

Hypoxic zones can occur naturally‚ but scientists are concerned about the areas created or enhanced by human activity. There are many physical‚ chemical‚ and biological factors that combine to create dead zones‚ but nutrient pollution is the primary cause of those zones created by humans. Excess nutrients that run off land or are piped as wastewater into rivers and coasts can stimulate

Tests were performed and samples were also gathered for analysis in the laboratory. Results were then collected as the basis for determination of the condition of the area being sampled. INTRODUCTION The intertidal area also called the littoral zone is where the land and sea meet‚ between the high and low tide zones. This complex marine ecosystem

Grade 11 Biology Bio Ecology Field Study By‚ Colton Hatcher Introduction Hastings Point is a small coastal town located in New South Wales that is sounded by a national park. Hastings point has been a great location for tourists due to its marine wildlife‚ beaches and fishing. This destination is home to a magnificent rocky shore perfectly suited for a vast majority and wide range of marine wildlife. The rocky shore has a wide spread of both biotic and abiotic factors which provides a

Moving About Inertia: What is Inertia? Inertia is a property of matter that causes it to resist changes in velocity (speed and/or direction) (Rouse‚ 2005). Basically Inertia is a word we use when we talk about matter and movement (Unknown Author‚ Unknown Date). This idea goes all the way back to Sir Isaac Newton‚ a great physicist. In Newton’s first law of motion it is stated that: 1. An object at rests tends to stay in rest 2. An object in motion tends to stay in motion A great example

the force that acts upon the object. By applying this aspect on a car’s safety systems‚ we are able to either reduce the risks of injuries as the results of a crash‚ or to avoid a crash completely. It is with this principle that seatbelts‚ crumple zones‚ air bags‚ and braking systems‚ among other features‚ are able to save us from such unfortunate events. Seatbelt – an active safety feature In America alone‚ seatbelts have saved an approximate of 13‚000 lives each year. Furthermore‚ an estimate

PART (1) Ellen Ryan Introduction This experiment was carried out in order to better understand Hong Kong’s ecology and biodiversity‚ specifically focusing on field-based whole organism biology in an area with little human interferences. Method 1. Lay a horizontal transect on the mid-shore (1.75m) 2. Repeat for high-shore (2.25m) 3. At regular intervals of 1m
