Answer

Brief Explanations:

  1. Parasitism is a non - cooperative relationship where a parasite benefits at the expense of a host, and it is similar to predation as one organism (parasite) exploits another (host), but parasites don't always kill their hosts immediately.
  2. Convection is the transfer of heat by the movement of currents (fluid or gas).
  3. Fossil fuels are widely used because they are readily available and relatively inexpensive, though they are non - renewable and harmful to the environment.

Answer:

  1. Parasitism is similar to predation.
  2. transfer of heat by currents.
  3. Fossil fuels are readily available and inexpensive
