What is Done to Something
Passive Voice
Use the passive voice to express that something is done to an object. The passive voice is especially useful in business situations when the focus is on the product, rather than the person who manufactures the product. The following structure is used for sentences in the passive voice.

In this case, it is understood that someone grows oranges in California. However, it is not important for the understanding of the sentence to include the agent.
