Study Notes
Earth System
- Earth's system comprises all the matter, energy, and processes within its boundaries.
- Matter stays within the Earth system, while energy enters as sunlight and exits as heat.
- Energy transformations occur within the system, driving matter cycling through different forms.
Four Spheres
- The Earth system is divided into four interconnected spheres: geosphere, hydrosphere, biosphere, and atmosphere.
- Geosphere encompasses all solid features of Earth's surface and below, including mountains, continents, and sea floor.
- Hydrosphere includes all Earth's water in liquid, ice, and vapor forms.
- Biosphere is the region where life exists, encompassing all living organisms.
- Atmosphere comprises the air surrounding Earth's surface.
Biosphere's Organization
- Biosphere is made up of ecosystems, which encompass all living and nonliving components in a given area.
- Organisms of the same species living in the same area form a population.
- Collections of different populations in an area make up a community.
- Communities exist within biomes, large regional or global areas characterized by climate and vegetation.
Biotic and Abiotic Factors
- Biotic factors refer to the living components of an ecosystem.
- Abiotic factors constitute the nonliving components of an ecosystem.
- Interactions and interdependence exist between biotic and abiotic factors within an ecosystem.
Characteristics of Living Things
- Living things are characterized by being made up of one or more cells, requiring energy sources, growing and changing over time, reproducing, and responding to environmental changes.
- Homeostasis maintains constant internal conditions in living organisms, ensuring their survival amidst changing environments.
Venus Flytrap as an Example
- Venus flytrap, as a living organism, demonstrates the characteristics of life.
- It obtains energy from sunlight and nutrients from captured insects.
- It exhibits both sexual and asexual reproduction methods.
