the proper order, from smallest to largest, for the levels of organization is
a. population, community, organism, biome, ecosystem, biosphere
b. organism, community, population, ecosystem, biome, biosphere
c. biosphere, biome, ecosystem, community, population, organism

The right option is; d. organism, population, community, ecosystem, biome, biosphere

The proper order, from smallest to largest, for the levels of organization is; organism, population, community, ecosystem, biome, and biosphere. Organism (a discreet and complete living things; plants, animals or microorganism that has cellular structure and perform physiological functions) is the smallest, followed by population (group of organisms of similar species living in a certain area), community (which is composed of different species within a specific area), ecosystem (which is composed of all the communities in a certain area including biotic and abiotic), biome and biosphere.
