Question

1. fill in the levels of biological organization from smallest to largest. cell → answer → answer → answer → answer individual → answer → answer → ecosystem

Explanation:

The levels of biological organization from smallest to largest (after cell) are: Tissue (group of similar cells), Organ (group of tissues), Organ System (group of organs), Population (group of same species individuals), Community (group of different species populations). And after Individual: Population, Community (before Ecosystem). So filling the blanks:

• Cell → Tissue → Organ → Organ System → Population
• Individual → Population → Community → Ecosystem (wait, correction: The correct sequence from cell is Cell, Tissue, Organ, Organ System, Individual, Population, Community, Ecosystem, Biosphere. But in the given diagram, after Cell, we have four blanks, then after Individual two blanks before Ecosystem. So:

Cell → Tissue (1st blank), then Organ (2nd), then Organ System (3rd), then Individual (4th blank? Wait no, the left side is Individual → [blank] → [blank] → Ecosystem. The right side is Cell → [blank] → [blank] → [blank] → [blank]. So correct sequence:
Right side (from Cell): Cell → Tissue → Organ → Organ System → Individual
Left side (from Individual): Individual → Population → Community → Ecosystem

Wait, let's recall the standard biological organization levels:

1. Cell
2. Tissue (group of cells)
3. Organ (group of tissues)
4. Organ System (group of organs)
5. Individual (organism)
6. Population (group of same species organisms)
7. Community (group of different species populations)
8. Ecosystem (community + abiotic factors)
9. Biosphere (all ecosystems)

So in the diagram:
Right column (starting with Cell):
Cell → Tissue (1st answer) → Organ (2nd) → Organ System (3rd) → Individual (4th)

Left column (starting with Individual):
Individual → Population (1st answer) → Community (2nd) → Ecosystem

So filling the blanks:

Right (Cell → ...):

1. Tissue
2. Organ
3. Organ System
4. Individual

Left (Individual → ...):

1. Population
2. Community

Answer:

Right column (Cell →):

1. Tissue
2. Organ
3. Organ System
4. Individual

Left column (Individual →):

1. Population
2. Community
