Riparian zones are important to the natural environment because they function as natural biofilters and protect the aquatic life and the aquatic environment.
The reason why a dichotomous key to identify organism is valuable, is because it helps you classify organisms,it helps you identify eco -systems, it helps you analyze an organism's traits.
Explanation:
A dichotomous key is a skill that has been brought about by scientists, to help people to identify and classify organisms.
In Dichotomous key, the main way of identifying an object is by it scientific name.This is because, though two objects might look similar to each other but they might belong to a whole different species.
So, it is is easier to identify the organism from its scientific name, as it will tell us which species it belongs to.
This key is very useful to people who are novice, and don't know much about identifying an organism.
This key also helps identifying, whether an organism belongs to a particular closely related group of organisms or is a separate organism.
It helps one analyze the traits of an organism, and based on their characteristics, it will help you identify and classify the species of the object or organism.
Answer:
A proton gradient is generated by the transport of protons into the thylakoid lumen.
Protons move from the thylakoid lumen to the stroma through ATP synthase, producing ATP.
Explanation:
During photosynthesis, the environment is made acidic inside the lumen i.e. H⁺ are pumped into thylakoid lumen from stroma as a result of which more H⁺ are present in the thylakoid lumen as compared to stroma. It happens during light dependent reaction of photosynthesis. The concentration of H⁺ is already higher in lumen and transfer of more and more H⁺ from stroma increases the concentration of H⁺ even more leading to generation of a potential gradient. These H⁺ subsequently tend to move freely from lumen to stroma via "reverse pumps known as ATP synthase". The reason why these are known as reverse pumps is because pumps usually move particles from lower to higher concentration which is an active movement i.e. not natural so such movement requires energy. Naturally particles move from higher to lower concentration gradient until the concentration becomes equal on both the sides but pumps act opposite of this natural process and move particles from lower to higher concentration and utilize energy to do it. But here H⁺ are moving from higher to lower concentration which occurs naturally so ATP synthase rather than using energy tend to generate energy and this free energy is used to generate ATP from ADP & Pi (inorganic phosphate).
