Diagram showing the 3 pathways of heat exchange |

In this diagram the lizard is:
1 gaining heat via radiation
2 gaining heat via conduction becasue its body temperature is lower than
the ground temperature
3 losing heat via convection because its body temperature is greater than
the air temperature
