Our sun release energy by a process called convection. Inside the star, energy is transported towards the surface through radiation, but about 1/3 of the outer layer of the star is markedly cooler than the core and the energy is transported by convection from the core to this layer.
The convection zone is how the energy from the core is transported to the photosphere. The plasma is heated, rises to near the surface, cools and then falls back toward the core to be heated again.
Radiation, convection
Energy from the core travels by radiation through the radiative zone, then by convection through the convection zone.

No, Convection does not occur in the Core. For example, in the Sun, the convection occurs only after the Radiation zone. In the radiation zone the energy is transported by radiation (ie, by photons). At about 0.8 solar radius the density and temperature are not enough to transport the energy by radiation, so convection sets in.
Mainly by radiation - however, the radiation quickly gets absorbed by an atom, and re-emitted, so it takes quite a while to reach the surface. In the outer part of the Sun, the energy also gets transported through convection.

Yes, both. In some regions of the Sun, mainly one method of heat transport is used, in others, mainly the other.
Conduction, convection and radiation.
The light is electromagnetic energy; so is the heat radiation. Heat transported through conduction or convection is no longer electromagnetic energy.
radiation carried by convection.
