Answer: O polar covalent bonds because oxygen is more electronegative than hydrogen
Explanation:
In the water molecule the two hydrogen atoms and one oxygen atoms forms the chemical structure in this the covalent bond is formed between hydrogen and oxygen and this is formed due to sharing of electrons between hydrogen and oxygen and oxygen being electronegative requires two electrons to complete its valency which are provided by two electrons each from one hydrogen and the O polar covalent bond is formed by this way.
Producers (plants) are important to our ecosystem because they are the base of life. If it wasn't for producers, you wouldn't be eating your salad while your reading this answer. That chicken you had yesterday wouldn't be there if it wasn't for corn (a producer).
