Exploring Sampling Techniques: Transects and Quadrats

To identify the species of organisms

To capture and relocate organisms

To measure the speed of organisms

To determine the abundance and distribution of organisms

A circular frame used for sampling

A square frame used for counting plants or slow-moving organisms

A net used for capturing insects

A device for measuring soil pH

To ensure the data is accurate and representative

To reduce the time spent sampling

To cover a larger area

To increase the number of species found

Using a random number generator to pick sample sites
