Carbon cycle is the movement of carbon from the atmosphere to the Earth.

Carbon move in the carbon cycle and start from the atmosphere.

In the atmosphere, carbon react with oxygen and it is inform of carbon dioxide. Plants use the carbondioxide along with water,and uses light energy from the sun to produce carbohydrates through a process of photosynthesis.

Animals get carbon from plants after consuming plants.

During respiration, carbon atoms are released to the atmosphere.

Some human activities like burning of fossil fuels releases carbon to the atmosphere.

When a pigment molecule in a light-harvesting complex absorbs a photon of light, what happens to its excited-state electron?.
MA_775_DIABLO [31]

When a pigment molecule in a light-harvesting complex absorbs a photon of light, While returning to its ground state, the electron transfers some of the energy from its excited state to an electron in a nearby pigment molecule.

  • It takes a photon of light energy some distance before it reaches a pigment molecule like chlorophyll.
  • An electron in the chlorophyll is "activated" by the photon. The energy imparted to the electron then moves from one pigment molecule to another until it reaches the reaction center, a pair of chlorophyll a molecules.
  • An electron in the reaction center is then excited by this energy, causing it to break loose and travel to the primary electron acceptor.
  • Therefore, it is said that the reaction center "donates" one electron to the main electron acceptor.

3A- Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.

3B- Negative feedback loops are used to maintain homeostasis and achieve the set point within a system. Negative feedback loops are characterized by their ability to either increase or decrease a stimulus, inhibiting the ability of the stimulus to continue as it did prior to sensing of the receptor.

Hope I’ve helped ;)
