-
An explanation of the process of photosynthesis including the reactants and products.
-
Photosynthesis is a process where plants use solar energy to produce sugar. This process converts light to chemical energy, which is stored in the sugars. Photosynthesis provides the oxygen that is used by all living things to survive. Also, photosynthesis removes carbon dioxide from the atmosphere, replacing it with oxygen. The process involves three reactants and produces three products. The reactants are light energy, carbon dioxide and water, while the products are sugar, oxygen and water. The photosynthetic process requires several simple reactants. Water is the first required reactant which the plant gets through its root. Then the plant absorbs carbon dioxide through its leaves and mixes these two things with the sun. The plant makes simple sugar which is stores and uses, and when the plant is eaten is used by other animals. Oxygen is also a product of photosynthesis and is released into the atmosphere through the plant’s leaves. Water is also a product of photosynthesis.

The process starts inside the chloroplast inside the thylakoids thesis thylakoids are stacked into Grana and the stroma is also inside of the thylakoids. The thylakoids have a membrane which is really good on staranfering protein and other things. Then a foton that is created by the sun chlorophyll gets hit by that photon an electron absorbs that energy and gets excited. Electrons gaining energy and not having anywhere to put it and when it's done by a photon it's called photo excitation. Now this electron that is very excited that when a special protein designed specifically for stealing electrons it leps of of the chlorophyll molecule on to the protein molecule which we call mobile electron carrier. Then it splits the ultra stable molecule H2O stealing one of its electrons to replenish the one it lost then the hydrogen ions and the single ions and sweet pure oxygen. This process is the reasoning that we have oxygen today in our day to daily lives to day my friends
2. An explanation of the processes that add carbon dioxide to the atmosphere.
-
Well carbon comes from every living thing into the atmosphere this happens every time you exhale you are releasing carbon dioxide gas in to our atmosphere. CO2 also known as carbon dioxide comes out of us when we breathe everyday in our daily lives. Animals get rid of CO2 gas through the process of respiration as well, but animal waste also adds to the amount of CO2 added to the atmosphere. Plants decomposing will add to the CO2 and finally, carbonite rocks over time with rainwater will dissolve and add CO2 to the atmosphere.
-
Humans have been burning fossil fuels to power factories, power plants, cars, and trucks and to make food and burn waste. This carbon very quickly enters through the atmosphere ar CO2 gas this is what is creating us as humans to have our world be global warmed.
3. An explanation of the importance of keeping the atmosphere in balance.
-
The Earth's temperature depend s on the balance between energy entering and leaving the plants system. When incoming energy is released by the sun is then absorbed by the earth's system. Then when the sun's energy is reflected back into space Earth the is avoiding global warming when all of the sun's energy is released by the sun and shot back into space from the Earth the Earth cools down so by us having factores here on Earth he are most definitely not helping the Earth's energy balance at all .
4. An explanation of the consequences of clearing forests.
-
Well the consequences are that if we cut down a lot of trees that we won have as much oxygen as we have now which is still not a lot of it. People are calling it Deforestation when we cut any amount of trees from the environment it can really hurt it and so can it hurt us with us find surent foods and all of that stuff that is important to us how can we now build our houses without having wood. Properly the biggest negative with deforestation is that we by cutting trees down are endangering millions of species that could go extinct if where not carfulwith the decisions that we make now. Also trees help prevent erosion, and they keep the land health, reducing landslides and mudslides. This would only make problems worse because if there isn't anything to eat then we starve of starvation because of our decision.
