17. All life on Earth under the atmosphere, including the lithosphere and the hydrosphere is ...(1 point)
[Choice A] a single ecosystem
[Choice B] a single biome
[Choice C] the biosphere
[Choice D] the hydrosphere
The correct answer is [Choice C] the biosphere. The biosphere refers to all living organisms on Earth, including those found in the atmosphere, lithosphere (land), and hydrosphere (water). It encompasses all ecosystems and biomes on the planet.
The correct answer is [Choice C] the biosphere.
To determine the correct answer, we need to understand the definitions of the given terms:
1. Ecosystem: An ecosystem refers to a community of living organisms interacting with each other and their physical environment.
2. Biome: A biome is a large geographic area classified by its predominant vegetation and characterized by specific climates and organisms adapted to those conditions.
3. Biosphere: The biosphere is the zone of the Earth where life exists. It includes all living organisms and their environments, including the atmosphere, lithosphere, and hydrosphere.
4. Hydrosphere: The hydrosphere encompasses all the Earth's water, including oceans, lakes, rivers, groundwater, and even water vapor in the atmosphere.
Now, let's apply this knowledge to answer the question:
The statement includes all life on Earth under the atmosphere, including the lithosphere (Earth's solid outer layer) and the hydrosphere (all water on Earth). Since it includes life on Earth as a whole, the correct answer is [Choice C] the biosphere. The biosphere represents the interconnected system where all living organisms exist and interact with their physical surroundings, encompassing all ecosystems and biomes on Earth.
