- Asexual reproduction: when one organism is able to make offspring without any other organism providing genetic material.
- Population: a particular group, or type of animals or plants living in an area or country... more
- Sexual reproduction: when two organisms join their genetic material (often eggs and sperm) to make a new organism.
- Thermodynamics: the study of energy or heat and related processes.
Learn about population ecology on Lizard Island. Our two Lizard Island games on Thermodynamics and Populations will teach players about the energy that must be collected and used to live and reproduce, as well as how different types of reproduction can affect population sizes.
Lizard Island – Thermodynamics: You might think lizards can lead lazy lives. But they are constantly on the search for food to fuel life and reproduction. Can you find enough food to make sure your genes make it to the next generation? Take the role of an asexual female lizard, a sexual female lizard, and a male lizard to find out what some of the costs and benefits of these roles are.
Lizard Island – Populations: We hear about population problems all the time… human populations are high and certain animal populations are too low. But how does population growth work? Have your calculators handy as you explore the world of populations and find out some of the things that control population size.
