which of the following shows the correct order for the biological hierarchy of life? (least complex to most complex)
population → ecosystem → community → biosphere
population → community → ecosystem → biosphere
tissue → cell → organ → organ system
cell → tissue → organ system → organ

Explanation:

1. Analyze the first option: A population is a group of the same species. A community is multiple populations. An ecosystem includes the community and its environment. The biosphere is all ecosystems. So "Population → Ecosystem → Community → Biosphere" is incorrect because ecosystem is more complex than community, so the order here is wrong.
2. Analyze the second option: Population (same species) → Community (multiple populations) → Ecosystem (community + environment) → Biosphere (all ecosystems). This follows the correct order of increasing complexity for the ecological levels of the biological hierarchy.
3. Analyze the third option: The correct order for the organismal level is Cell → Tissue → Organ → Organ System. So "Tissue → Cell → Organ → Organ System" is wrong because cells make up tissue, not the other way around.
4. Analyze the fourth option: The correct order is Cell → Tissue → Organ → Organ System. So "Cell → Tissue → Organ System → Organ" is wrong because organs make up organ systems, not the other way around.

Answer:

B. Population → Community → Ecosystem → Biosphere
