12. Ecologists study the relationships between flora and
fauna (plants and animals), and their environment. What is
the proper listing of the levels of ecological organization from smallest to largest? (1 point)
[Choice A] population—>ecosystem—->organism
—->biosphere—>community—>biome
[Choice B] community—>biosphere—>organism
—>population—>biome—>ecosystem
[Choice C] organism—>population—>community
—>ecosystem—>biome—>biosphere
[Choice D] biosphere—>ecosystem—>organism
—>community—>biome—>population
The proper listing of the levels of ecological organization from smallest to largest is:
[Choice C] organism—>population—>community —>ecosystem—>biome—>biosphere
The proper listing of the levels of ecological organization from smallest to largest is:
[Choice C] organism—>population—>community—>ecosystem—>biome—>biosphere.
To determine the proper listing of the levels of ecological organization from smallest to largest, we need to understand the hierarchy of ecological organization. Let's analyze the given choices:
Choice A: population—>ecosystem—>organism—>biosphere—>community—>biome
Choice B: community—>biosphere—>organism—>population—>biome—>ecosystem
Choice C: organism—>population—>community—>ecosystem—>biome—>biosphere
Choice D: biosphere—>ecosystem—>organism—>community—>biome—>population
To find the correct order, we can start by examining the definitions of each level:
1. Organism: An individual living thing, such as a plant, animal, or microorganism.
2. Population: A group of organisms of the same species living in the same area and interacting with each other.
3. Community: All the populations of different species living and interacting in a particular area.
4. Ecosystem: A community of organisms and their physical environment, including both living (biotic) and non-living (abiotic) components.
5. Biome: A large-scale area with specific climate conditions, characterized by dominant plant and animal communities.
6. Biosphere: The highest level of organization, including all of Earth's ecosystems.
Based on these definitions, the correct order is:
Organism—>Population—>Community—>Ecosystem—>Biome—>Biosphere
Therefore, the correct choice is Choice C: organism—>population—>community—>ecosystem—>biome—>biosphere.
