Year 7 Science 2025 – Success Criteria: Biology - Classification

Classification is defined as:

• The process of grouping things based on similarities

• The process of breaking things into smaller parts

• The process of measuring objects

• The process of labeling objects randomly

Classification helps in organizing information efficiently. Which of the following is an advantage of classification?

• It makes information more confusing.

• It reduces the accuracy of data.

• It increases the complexity of information.

Different ways of presenting information on dichotomous keys include which of the following?

• Only pictorial keys

• Numerical keys and alphabetical keys only

• Flowcharts and pie charts

A branching dichotomous key is used to classify which of the following?
