What were early civilizations more likely to fight over

Early civilisations were most likely to fight over control over limited resources. Because at that time civilisations did not have the capability to travel far for food and water, they had only what they found around them when they settled, but what they found was often already being coveted by another group, so the only option was to fight until one group won out.

Plants take energy from the sunlight with the of chlorophyll so the plant starts the food chain. then an herbivore eats the plant and gets its energy.then a carnivore or a human eats the herbivore and gets its energy. : )
