Explanation:

1. Levels of Organization: The biosphere is the global sum of all ecosystems, the largest level. An ecosystem consists of a biological community and its physical environment. A population is a group of the same - species organisms in a given area.
2. Habitat vs Niche: A habitat is the natural environment where an organism lives. A niche is the role and position an organism has in its environment, including its interactions with other species and its use of resources.
3. Abiotic vs Biotic Factors: Abiotic factors are non - living components of an ecosystem such as sunlight, water, and temperature. Biotic factors are living organisms in an ecosystem, including plants, animals, and microorganisms.

Answer:

1. Levels of Organization (from largest to smallest): Biosphere, Ecosystem, Population
2. Habitat: The natural place where an organism lives. Niche: The role and position of an organism within its environment.
3. Abiotic factor: Non - living components of an ecosystem. Biotic factor: Living organisms in an ecosystem.
