You might have thanked the trees for giving oxygen but never phytoplankton. What can they do except try to steal the Krusty Krab formula? Well‚ what if I said that without phytoplankton‚ the entire marine ecosystem collapse‚ an increase of 1/3 accumulation of CO2‚ and oxygen drop up to 50 percent in the atmosphere‚ which will lead to human extinction. Sounds dramatic‚ but it is true. I seriously think that we need to care more about these planktons‚ since they are not unlimited in the ocean‚ and

air from escaping. The warmed structures and plants inside the greenhouse re-radiate some of their thermal energy as glass is partly opaque causing convection due to energy trapped inside the glasshouse. The blanket layer of gases in particular carbon dioxide traps much heat and prevents it from escaping back into space as radiation. Mother Earth is gradually warmer as air is trapped as created by the ‘greenhouse effect’. The air that is warmed near the ground is prevented from rising and flowing away

Aerobic respiration provides the energy required by all living organisms to function normally‚ as muscle movement and certain cell reactions are reliant on energy the transport of oxygen to the cells of tissues and organs by blood vessels is vital for respiration to occur. Oxygen is carried in red blood cells by the pigment haemoglobin‚ a globular protein consisting of four polypeptide chains. Both of these components of blood are structured specifically to carry out their functions of oxygen transport

discovery of plausible pathways for the transition from complex prebiotic chemistry to simple biology‚ defined as the emergence of chemical assemblies capable of Darwinian evolution. A coherent pathway which starts from no more than rocks‚ water and carbon dioxide and leads to the emergence of the strange bioenergetics properties of living cells has been traced back to what is now called as Protocells. A Protocell is found to be the first form of a cell before true cells arose. They have a lipid protein

Oxygen – Carbon dioxide Cycle The Carbon Dioxide- Oxygen Cycle relates to the relationship between Carbon Dioxide [CO2] breathing plants and Oxygen [O2] breathing life forms. All oxygen-breathing life forms take in Oxygen and exhale CO2. Plants take in the CO2 and use it in their photosynthesis process and in turn give off oxygen. The Carbon Dioxide-Oxygen Cycle is a continuously occurring process whereby animals inhale Oxygen and then exhale carbon dioxide‚ and plants use the CO2 and "exhale"

and that may result from the greenhouse effect. Thus there is no indication that the warming between “1975-1998” and “1975 to 2009” is unnatural‚ unusual and/or caused by anthropogenic carbon dioxide emissions. Global Warming may have started in 1975‚ but there is no observable evidence of anthropogenic carbon dioxide emission based global warming began in 1975. Most climate scientists agree the main cause of the current global warming trend is human expansion of the “greenhouse effect” warming that

38 ATPs c. What reactants of ATP must be available in the cell in order to produce ATP? O2 d. Brainstorm several cellular processes for which energy or ATP is necessary. Oxidization Glucose‚ or any carbon-based molecule‚ can be burned in oxygen (oxidized) to produce carbon dioxide and water. Combustion reactions release large amounts of energy. However‚ the energy release is uncontrolled. An organism would not be able to handle all that energy at once to do the work of the cell. Cellular

less carbon dioxide being removed from the air. Increases of green house gases trap more heat from the sun within the Earth’s atmosphere. When this happens‚ the Earth tends to stay warm. This causes the ice caps and glaciers to melt and the sea levels to rise. This will cause more storms‚ flood‚ and droughts and plants‚ people and animals will die. The Earth’s temperature is increasing due to the greenhouse gases being released. For example‚ when we burn coal and oil‚ we release carbon dioxide‚ methane

created by carbon dioxide emissions‚ released from the burning of fossil fuels (coal‚ oil and gas) in rich countries and a constantly increasing number of cars. Humans generate about 24 billion tonnes of carbon dioxide each year. It doesn’t take long to realise that there is no realistic chance of solving the greenhouse problem by planting trees to remove carbon dioxide from the atmosphere. Firstly we’d have to plant something like the area of Australia‚ and secondly this would only take carbon from the
