You will write a two-paragraph summary of how photosynthesis and cell respiration are related. In your first paragraph address the cycling of matter--be specific! How does one process provide the raw materials for the other and vice versa? In your second paragraph, discuss the flow of energy that takes place in an ecosystem. Be sure to discuss the initial energy source as well as the role of photosynthesis and cell respiration. Notice that respiration is not an entirely efficient process and some of the energy produced is lost as heat. Address the need for continual energy input to the ecosystem. This is not a cycle!

explanation:

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

explanation:

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
