NAME: NABILAH HAMDIAH CLASS: 4K2 In the film that was shown to us by our Biology teacher‚ Miss Fairuz Adlidna‚ there were two different ecosystems that were being displayed‚ a marine one and a tigers’ habitat for the other. Based on my observation‚ I have decided to make a film review on the marine ecosystem. Through a documentary that was based in the United Kingdom‚ “INSIDE LIFE”‚ a young boy called Sam Wigfield was offered the opportunity to be a part of the shooting crew. His job was

Trashed: Our Ocean By: Meaghan Todd December 10th 2010 CGW-4U1-02 Mr. Kyriacou Have you ever been to the beach? I have and swimming in the ocean is one of my favourite things to do when I go on vacation! You wouldn’t want someone to come into your house and throw their cigarette butts or their plastic drink container on your kitchen floor when they’re done would you? I know I wouldn’t. Littering in the ocean does not magically get rid of your garbage; the marine wildlife

Scientific Article: The Ozone Layer The Ozone layer is located in the Earth’s upper atmosphere. It acts as a barrier and absorbs majority of UV radiation before it hits Earth’s surface. Ozone is made up of three oxygen atoms that are naturally occurring molecules. The depletion of the ozone has become a worldwide issue and is caused by the release of CFCs into the atmosphere. CFCs release chlorine atoms which break down ozone molecules. The depletion of the ozone layer threatens to leave life on

of iron (Fe) and copper (Cu) availability on the growth rates‚ Cu quotas‚ and steady-state Cu-uptake rates (ρssCu) of 12 phytoplankton (from four classes and two marine environments). A mixed-effect statistical model indicated that low Fe significantly decreased phytoplankton growth rates. In contrast‚ lowering Cu levels only decreased the growth rates of the oceanic phytoplankton. Under Fe/Cu sufficiency‚ the Cu quotas ranged from 0.36 to 3.8 μmol Cu · mol−1 C. Copper levels in the growth medium had

IMPACTS OF OZONE Introduction Ozone is a gas that occurs naturally in our atmosphere. Most of it is concentrated in the ozone layer[->0]‚ a region located in the stratosphere several miles above the surface of the Earth. Although ozone represents only a small fraction of the gas present in the atmosphere‚ it plays a vital role by shielding humans and other life from harmful ultraviolet light from the Sun. Human activities in the last several decades have produced chemicals‚ such as chlorofluorocarbons
