Answer:
Iron is being oxidized. (Ans. B)
Explanation:
Half reaction is defined as either the reduction where electrons are gained or oxidation where electrons are lost of the redox reaction. Half reaction is produced by change in the oxidation state of individual molecule which is involved in the redox reaction.
A good example of redox reaction is known as rusting. In this process oxygen take electrons from iron, then iron gets oxidized, and oxygen gets reduced. This process results the compound known as rust, or iron oxide.
Fe----> Fe2+ +2e-.
The element itself is Yttrium, which is a transition metal and not that reactive. Since it has 39 protons it will also have 39 electrons.
Explanation:
I don't think a decomposer and detritvore would compete with each other because decomposers job is to break down dead, organic materials and detritvores feed on dead organisms
