Objectives
3
Live in freshwater environments
They need food, water, and space to grow at their rapid pace.
The carrying capacity is the greatest number of individuals a given environment can hold.
Competition for resources among members of a population places limits on population size.

Draw
Use the table to record the number of cells of each type of paramecium each day.
Note: The well in the microscope slide holds 0.5 mL. You need to double the number of cells you counted or estimated to get the concentration per milliliter.

Multiple Choice
What role does the rice play in the test tubes during the experiment?
The rice is food for the scientist.
The rice is food for bacteria - which is food for the paramecium.
The rice soaks up the extra liquid in the test tube.
The rice is a home for the paramecium to live in.
