Define the following ecological terms: Niche, Ecological Climax, Population, Environment, Lithosphere, Biosphere, Atmosphere, Hydrosphere, Habitat, Ecosystem.

Here are the definitions for the terms you provided:

1. Niche: The specific role or function an organism plays in its ecosystem, including its interactions with other organisms and its physical environment.

2. Ecological Climax: The final, stable stage of ecological succession, where the community of plants and animals remains relatively unchanged over time until disturbed by external factors.

3. Population: A group of individuals of the same species living in the same geographical area at the same time.

4. Environment: The sum of all external conditions and influences that affect the life and development of an organism or a population.

5. Lithosphere: The rigid, outermost shell of a terrestrial-type planet or natural satellite, consisting of the crust and the uppermost mantle.

6. Biosphere: The part of Earth where life exists, encompassing all ecosystems and living organisms, from the deepest oceans to the highest atmosphere.

7. Atmosphere: The layer of gases surrounding Earth, held in place by gravity, which protects life on Earth by absorbing ultraviolet solar radiation and moderating temperature.

8. Hydrosphere: All the water on Earth's surface, underground, and in the air, including oceans, lakes, rivers, glaciers, and water vapor.

9. Habitat: The natural home or environment of an animal, plant, or other organism.

10. Ecosystem: A community of living organisms (biotic components) interacting with their non-living physical environment (abiotic components).

11. Ecology: The scientific study of the relationships between living organisms, including humans, and their physical environment; it considers how these interactions shape the distribution and abundance of organisms.
