In the light dependent reactions light energy is absorbed by the photosytem II and an electron is released. This electron causes a process called photolysis to occur(H20-->2H++2e-+1/2O2). This is how O2 is released in the atmosphere. The electrons resulted from photolyisis enter the electron transport chain. In the electron transport chain using the energy in the elecrtons, hydrogen protons are pumped inside the thylakoid. Those protons accumulate to form an electrochemical gradient. That means the protons need to flow out, and they do through an enzyme called ATP-synthase which turns ADP and inorganic phosphate into ATP and water. In the electron transport chain, the electrons reach Photosystem I where NADP+ is reduced and becomes NADPH.
ATP and NADPH store the energy absorbed in the light dependent reactions. Those two molecules are needed when CO2 is fixated in Calvin's cycle to synthesize glucose.
the nutrients will not be absorbed in our body
Explanation:
eg. if proteases were not in our body we will not be able to absorb proteins
Answer:
The biosphere is made up of the parts of Earth where life exists—all ecosystems. The biosphere extends from the deepest root systems of trees, to the dark environments of ocean trenches, to lush rain forests, high mountaintops, and transition zones like this one, where ocean and terrestrial ecosystems meet.
The salmon is a key player in the food web whose removal may cause an imbalance in the whole ecosystem.
<h3>What is a food web?</h3>
A food web is a graphical diagram representing all connections between organisms in a given ecosystem.
Salmon represent the food for different types of animals in a food web, thereby their removal may cause serious harm to the balance of the ecosystem.
Salmon fish is a tertiary consumer because they eat herring which in turn eat zooplankton that eats phytoplankton.
