Convection - hot air raises -- smoke and other hot air goes up. Conduction - anything in contact with the fire - a pot, a poker, etc conducts the heat Radiation - some of the energy ( heat) is released as infrared (heat) waves you can feel the heat without touching the fire thru radiation of these i-r waves.
No. Not unless the person touches the BBQ. More a case of heat radiation.
You are correct because the heat of the fire causes the hot air to rise quickly by convection currents and the intense radiated heat ignites materials like fabrics, plastics and light wooden objects like chairs.
Conduction
Convection.
convection causes the heat transfer.
the smoke
Heat, smoke, and the consumption or change of the fire's object.
radiation
Well usually the smoke will suffocate you first, but it's a totally different story if you catch on fire. The heat itself won't kill you because the smoke or fire will get to you before any heatstroke/heat exhaustion comes along.

No, not at all. There can be heat without flame. Something can smolder and put out more smoke than something that is at a rolling fire.
yes because not enough heat
Fire or heat
heat, oxygen & fuel
The friction caused by rubbing the sticks together causes heat causes the fire
