The method of heat transfer by which the sun energy reaches the earth is a) conduction b) convection c) radiation d) solaration

Radiation

Explanation:

The sun is a huge ball of gaseous that is very hot and it transfer the energy to the earth. The temperature of the earth is maintained by the the radiation from the Sun.

The radiation from the sun brings heat to earth that helps to maintain the various process on earth. The radiation falling on earth is absorbed and some of the radiation is reflected back.

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.
