- BIOLOGY ASSIGNMENT Aim: To investigate the types of producers and animals in the tidal rock-shelf ecosystem and the adaptations of organisms in that environment. Also‚ to measure biotic and abiotic components and the distribution and abundance of organisms to the tidal rock- shelf ecosystem. Introduction: Long Reef Marine Reserve was established in the 1980’s to protect the extremely diverse marine life that makes the most of this environment. The Marine reserve covers the large rocky

has the world’s fourth highest tidal range with up to 10 meter high spring tides and 7 meter high neap tides. Due to the narrowing of the river from over 3 miles wide in parts and the size of the tides‚ speeds of water behind all three landing stages can regularly get up to 7 Knots (8MPH). This causes numerous under currents around all three of the landing stage areas and can sweep a person entering into the water away in a few seconds. Tidal Range = difference between Low Water

Waves ‚ Tides and Sediment Cells L.O. = to compare and contrast constructive & destructive waves‚ to understand wave refraction‚ to understand the difference between spring and neap tides and to identify the UK’s sediment cells. Wave Characteristics Wavelength = the distance between the crest of two adjacent waves. Wave Amplitude = the distance between sea level and the crest. Wave Crest =the highest point of the wave. Wave Trough = the lowest point of the wave. Wave Height = the distance

INTERTIDAL WETLANDS • Intertidal wetlands develop in coastal areas which are subject to periodic inundation by salty water • They are found in estuarine environments in the limits of the tidal range • Previously thought of as mosquito infested wetlands‚ they are now considered highly valued ecosystems which protect the quality of coastal waters and provides breeding grounds and habitats for a variety of marine life‚ are found along tropical and sub-tropical coastlines between 25ْN and 25ْC •

Tides slow the Earth’s rotation speed in two ways. First‚ tides slow Earth’s rotation with tidal friction (such as bottom friction or the breaking of the waves). This effect causes a very slow‚ steady change in Earth’s rotation. It causes the rotation to slow by about 2 hundred-thousandths of a second each day‚ and it adds twenty seconds to each

always within the “normal” range for the human body? Yes 6. Did the PCO2 level change during the course of normal breathing? If so‚ how? No Activity 2a: Hyperventilation – Run 1 1. At 20 seconds‚ pH = 7.47 2. At 40 seconds‚ pH = 7.52 3. At 60 seconds‚ pH = 7.67 4. Maximum pH = 7.68 5. Did the pH level of the blood change at all during this run? If so‚ how? Yes‚ it increased and it did not remain completely steady. 6. Was the pH level always within the “normal” range for the human body?

profile Distribution and abudance of organisms‚ i.e.‚ Batillaria sp.‚ bivalves and crabs Discussion Abundance and distribution of organisms Bivalves are distributed along from 2.5m to 47.5m away from the coastline. The graph shows a large range of distribution. As sea water also brings food for bivalves‚ wherever the sea water can reach‚ bivalves can live there. Therefore‚ bivalves have a wide distribution along the transect line. For the abundance‚ it is quite even along the transect line

oxidation rate? Pyrite oxidation generates O2 and produces heat. Due to this‚ the acidity and temperature of the surrounding soil/solution will affect the overall reaction rates (4). Biological oxidation only occurs between 0oC and 55oC with an optimum range of 24oC – 45oC (4)‚ but chemical oxidation can happen at a much higher temperature. It is predicted that the PASS will oxidize at a much faster rate if the temperatures are at the higher end of the scale as it is known that higher temperatures increase
