The various types of symbosis include: 1  parasitism-one species (parasite) benefits more than the other species (host). 2  commensalism-one species benefits while a second species is neither helped nor injured. 3  mutualism-both species benefit from the interaction.he various types of symbosis include: 1  parasitism-one species (parasite) benefits more than the other species (host). 2  commensalism-one species benefits while a second species is neither helped nor injured. 3  mutualism-both species benefit from the interaction.
Many different types of energy can be converted into heat energy. Light, electrical, mechanical, chemical, nuclear, sound and thermal energy itself can each cause a substance to heat up by increasing the speed of its molecules.
Thermal energy is a part of the total energy of any object. Thermal energy is related to the temperature of an object. The joule is the unit used to measure thermal energy. Unlike other forms of energy, thermal energy is difficult to convert to other forms of energy. When thermal energy is transferred from or to an object, it is called heat. Since heat is known as a process, objects cannot contain heat. Objects contain thermal energy.
