In which type of economy do we typically see very poor people living subsistence lifestyles where the gathering of food and fuel takes place on a daily basis?

I would say a mixed economy or a 3rd world economy

The earth's inner core is the earth's innermost part. it is primarily a solid ball with a radius of about 1,220 km (760 miles), which is about 70% of the moon's radius.[1][2] it is composed of an iron–nickel alloy and some light elements. the temperature at the inner core's surface is approximately 5,700 k (5,430 °c), which is about the temperature at the surface of the sun.
