Answer:
An ecosystem is a natural system that consists of organisms and their abiotic environment, and the interactions between the two, within a defined geographic space.
An ecosystem is a natural system that consists of living organisms and their plant, climatic and geographical environment, delimited within a specific space in which they interact and interrelate with each other.
In the concept of ecosystem, the geographical location is very important, as the context of it will develop in a very different way given the climatic and geographical conditions of the place: for example, a desert has very different conditions than a jungle; the animals that live there are totally different, as are the vegetation and other characteristics of the environment.
Thus, the altitude and latitude of a certain place decisively affect said environment, affecting the conditions of the ecosystem: the further from the equator or higher the ecosystem is, for example, it will be colder, with which the life that develops there it should be adapted to that context.
In Guyana and Suriname, the dominant ethnic group is made up of people descended from workers who migrated from India. East Indian’s are the largest ethnic group in Suriname, comprising approximately 27% of their population. While in Guyana, East-Indians are the largest ethnic groups as well — forming at about 43.5% of their population.
Africa, Asia, and South America are the three continents that are partly in the northern hemisphere and partly in the southern hemisphere.
Africa, Asia, and South America lie in both hemispheres. The Equator divides the earth into two equal halves. The upper half is called as Northern hemisphere and the lower half is called as Southern Hemisphere. All these continents are mostly in the torrid zone and from these three continents, only the equator crosses.
On the African continent, there are 54 countries today making it having most countries on the continent. Whereas Asia is comprised of 48 countries and South America is comprised of 12 countries.

A. Used fire to do controlled burns
The result of controlled burns were highly beneficial to both the Aborigines and the environment. The burnt remains of the burns were very fertile and encouraged the growth of new vegetation that would not have been able to flourish if the older growth had not been removed. The removal of old vegetation also resulted in a low chance of wild fires. Further more new vegetation was able to attract wildlife to graze, making hunting easier.
The concept of controlled burns is still used today and was/is also practiced by First Nations in North America.
