Question

1. which of the following sequences represents the hierarchy of biological organization from the most inclusive to the least complex level?

a. organelle, tissue, biosphere, ecosystem, population
b. organ, organism, tissue, organelle, molecule
c. organism, community, biosphere, molecule, tissue, organ
d. biosphere, ecosystem, community, population, organism

Explanation:

To determine the correct sequence of biological organization from most inclusive to least complex, we recall the hierarchy: Biosphere (all ecosystems) → Ecosystem (community + environment) → Community (all populations in an area) → Population (same species group) → Organism (individual living thing). Let's analyze each option:

• Option a: Organelle (too small) and order is wrong (biosphere should be first, not after tissue). Eliminate.
• Option b: Order is incorrect (organ should be after tissue, and molecule is too small here; also, organism is not more inclusive than organ). Eliminate.
• Option c: Molecule is too small, and the order of biosphere, community, organism is jumbled. Eliminate.
• Option d: Follows the hierarchy: Biosphere (most inclusive) → Ecosystem → Community → Population → Organism (least complex among these levels).

Answer:

d. biosphere, ecosystem, community, population, organism
