Ecology Fall Final Exam Review 24-25

Front

What is a dependent variable?

Back

The dependent variable is the variable that is measured or observed in an experiment. It is affected by changes in the independent variable.

Front

Identify the dependent variable in a plant growth experiment.

Back

Height of plants.

Front

What is an independent variable?

Back

The independent variable is the variable that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

Identify the independent variable in a plant investigation setup.

Back

Soil pH.

Front

What is an experimental group?

Back

The experimental group is the group in an experiment that receives the treatment or intervention being tested.

Front

What is a control group?

Back

The control group is the group in an experiment that does not receive the treatment and is used as a benchmark to measure how the other tested subjects do.

Front

What does cause-and-effect mean in scientific experiments?

Back

Cause-and-effect refers to the relationship between two events where one event (the cause) makes the other event happen (the effect).

Front

What is the purpose of a hypothesis in an experiment?

Back

A hypothesis is a testable prediction about the relationship between the independent and dependent variables.

Front

What is the significance of replicating experiments?

Back

Replicating experiments helps to verify results and ensure that findings are reliable and not due to chance.

Front

What is the role of sunlight in plant growth experiments?

Back

Sunlight is often an independent variable that can affect the growth of plants, influencing their height and health.
