I don't understand ur question. Hmm
Answer:
The correct answer is - photosystem II; ATP; water; oxygen
Explanation:
The photosynthesis process involves two different cycles known as the light reaction and the dark reaction. In light reaction there are two photosystems; photosystem I and photosystem II.
During light reaction, there are several pigments such as chlorophyll a and other pigments present in photosystem II that trap the light and transfer excited electrons through ETC to produce ATP which is a form of energy used by cells.
A water molecule takes place of the excited electron that is transferred and releases oxygen as waste or byproduct in this reaction.
Environmental scientists are using GPS ( It is effective but expensive) aerial monitoring (Quick but not the easiest), RFID tags, (mostly for long-term monitoring) and hidden cameras are used to study polar bear behavior without interruption to their environment.
