12.2 Regualtion of Body Temperature

Methods

Heath can be lost and gained from/too the environment via:

• Conduction: This is where particles vibrate against each other, and pass kinetic energy between them.

• Convection: This happens in liquids and gasses and is where the heat causes the object to move, and therefore take the heat with it.

• Radiation: Electromagnetic waves hit a particle, causing it to heat up. 

Endotherms: Organisms that mainly produce heat from within themselves through metabolic reactions.

Ectotherms: Opposite.

Ectotherms

The example I am using is a lizard:

Heat Gain:

• Lying on a warm rock in order to gain heat through conduction.
• Lying in direct sunlight.
• Metabolic reactions.
• In cooler countries, they have darker skin in…
