Identify the correct flow of energy through a living system?

Answer 1

The process is photosynthesis, in which plants make use of light energy, water and carbon dioxide to make food (glucose). oxygen and water is formed as a waste product. the equation for this reaction is 12H2O + 6CO2 --> C6H12O6 + 6O2 + 6H2O. Since plants are the producers, almost all living things depend on them to obtain their energy. The energy (in food) is passed down from one organism to another along the food chain.

Respiration is also needed. In respiration, food substances are oxidised to release energy in living cells. Aerobic respiration is the breakdown of food substances in the presence of oxygen with the release of a large amount of energy. carbon dioxide and water are released as waste products . C6H12O6 (glucose) + 6O2 --> 6CO2 + 6H2O

Therefore, the process of photosynthesis supplies living things with the energy that they need in the form of food, while respiration releases the energy found in the food. for the cell's use.

However, it has been found that there is life way deep down underwater where there is no light (because all the light has been absorbed nearer to the surface of the water). the starting energy could possibly be geothermal energy from volcanic activity nearby.

Answer 2

you being alive is a continuous cycle of production and consumption of energy. you need a virtually non-stop supply of fuel to keep all of the processes going in your body. now, imagine that on a scale of every living creature... !

Answer 3

Most energy starts with the sun.

Solar energy is transformed into carbohydrates, sugars and other materials through plants (everything from algae to Redwoods). Plants also put out oxygen from the CO2 they absorb. The carbon is used as a building block for the materails they make. The plants also "fix" an amount of nitrogen to nitrates and nitrites.

Animals eat the plants to absorb the produced molecules and breathe the oxygen. The animals create energy by "burning" the food in their cells. This becomes heat and electricity for nerve impulses.

The animals defecate and/or die providing food for scavengers and nutrients to plants.

Now for the exceptions ...

Deep under the oceans there are areas with volcanic vents (black smokers) which pump out sulfides and methane. Certain bacteria take the plants' job and use this source of energy and alternate oxidants to create proteins sugars and starches in an alternate manner. Bigger critters eat them and the situation reduces to the above case.

Answer 4

There are mitochondria in every animals (and humans) cell. The mitochondria are called the power houses of the cell. They produce energy. The cells then pass along energy and ding...energy. This process happens quite fast too.
