Verified step by step guidance

1. Step 1: Understand the concept of biological organization. Biological organization refers to the hierarchy of complex biological structures and systems that define life, ranging from the smallest unit to the largest.
2. Step 2: Review the levels of biological organization. The levels typically include atom, molecule, cell, tissue, organ, organism, population, community, ecosystem, and biosphere.
3. Step 3: Identify the lowest level of organization in the environment. The atom is the fundamental unit of matter and represents the lowest level of biological organization, as it forms the basis for all other levels.
4. Step 4: Compare the other options provided. Population refers to a group of organisms of the same species living in a specific area, organism refers to an individual living entity, and individual is synonymous with organism. These are higher levels of organization compared to an atom.
5. Step 5: Conclude that the atom is the correct answer because it is the smallest and most basic unit in the hierarchy of biological organization.
