Solution:

Ecology is basically concerned with four levels of biological organization - organisms, populations, communities, ecosystems, and biomes.
A population is a group of similar individuals in a particular geographical area or space. Community is the assemblage of interdependent and interacting populations of different species present in an area. The ecosystem is the sum of the biotic (living) and abiotic (non-living) components of a particular geographical area. The biosphere also called the ecosphere or giant ecosystem is the largest and nearly self-sufficient biological system. It is formed of all the ecosystems of the world. It is also called the life-supporting zone of the earth.
