there are several losses in a transformer that prevent it from attaining 100% efficiency. One is core loss, which can be divided into Hysteresis losses, Eddy currents and Magnetostriction loses. see for more details http://en.wikipedia.org/wiki/Transformer#Energy_losses
its efficiency will decresed.
A: Must understand this A transformer transfer power minus efficiency to another level that all it does.

Perhaps an electrical AC transformer can have 99 percent efficiency. A loudspeaker can have only 1 percent efficiency.
The "all day" efficiency of a transformer is defined as the ratio of energy out/energy in for a given all day cycle.
the efficiency is maximum in a transformer when no load loss is equal to load loss.

nope
.98 is 98 percent
For a single-phase transformer, maximum efficiency typically occurs at around 50-70% of the rated load. Operating the transformer at this load range minimizes losses and improves efficiency. Going below or above this range can decrease efficiency and increase losses in the transformer.
its efficiency will decresed.
The maximum efficiency condition in distribution transformer is said to be occurred when iron loss = copper loss
