Ahealthy environment depends on biogeochemical cycles maintaining a balance of input and output. when forests are cut down, which process of the carbon cycle is most affected? cellular respiration decomposition photosynthesis transpiration i will give brainliest

The correct answer is photosynthesis.  

In Earth Science and Ecology, cycling of substances or biogeochemical cycle refers to a passageway by which a chemical component moves via biosphere (biotic) and lithosphere, atmosphere, and hydrosphere (abiotic) segments of Earth.  

The most essential biogeochemical cycles are the nitrogen cycle, carbon cycle, phosphorus cycle, oxygen cycle, and the water cycle. The biogeochemical cycles always help in attaining a state of equilibrium.  

As the biogeochemical cycle helps in sustaining a balance of input and output, so in case if the forests are cut down, then one process of the carbon cycle, that is, photosynthesis gets highly affected. It is the procedure by which green plants utilize sunlight to produce foods from water and carbon dioxide.  

Photosynthesis

Explanation:

The carbon cycle is the one of the biogeochemical cycle in which the compounds of carbon circulates among the spheres of the earth like biosphere, hydrosphere, atmosphere, lithosphere and pedosphere.  The process of deforestation occurs when the forests are removed from a location. As a result of deforestation photosynthesis will not occur. This is because of the fact that plants are the main source of carbon sink. The plants absorb carbon dioxide from the atmosphere which is used as an ingredient for the synthesis of food (carbohydrates). In the absence of plants and trees the abundance of carbon will increase in the atmosphere and other spheres. This will disturb the balance of input and output sources of carbon in the carbon cycle.

first, consult an activity series chart to determine if al is more reactive than fe. it is, so it will replace the fe. now, one can continue with the problem.

next, make sure you have a correctly balanced equation.

3feo + 2al ==> 3fe + al2o3

now, determine which reactant (feo or al) is in limiting supply.

moles feo present = 125 g x 1 mole/71.8 g = 1.74 moles

moles al present = 25.0 g x 1 mole/26.98 g = 0.927 moles

since from the balanced equation, it take 3 mol feo for every 2 mol al, al will be limiting.

you can determine this simply by dividing moles of each by their coefficient in the balanced equation. for example: 1.74/3 = 0.58 and 0.927/2 = 0.464. al is less, so it is limiting.

finally, using the stoichiometry in the balanced eq. determine mass of fe that can be produced from 0.927 moles of al.

0.927 moles al x 3 moles fe/2 moles al x 55.8 g/mole = 77.6 g
