Identify the independent variable, dependent variable, and three possible controlled variables in the experiment where a wire fence is placed around half of a strawberry patch to test if rabbits are eating the strawberries.

• Independent variable: Presence of wire fence; Dependent variable: Number of strawberries with bite marks; Controlled variables: Amount of sunlight, type of soil, amount of water.

• Independent variable: Type of strawberry; Dependent variable: Height of plants; Controlled variables: Number of rabbits, type of fence, amount of fertilizer.

• Independent variable: Number of rabbits; Dependent variable: Growth rate of strawberries; Controlled variables: Size of patch, type of wire, frequency of watering.

• Independent variable: Amount of water; Dependent variable: Color of strawberries; Controlled variables: Presence of fence, type of soil, number of plants.
