Study Notes
Earth's Spheres
- Hydrosphere: All water on Earth, including oceans, lakes, rivers, groundwater, and ice.
- Biosphere: All living things on Earth, from microscopic bacteria to giant whales.
- Atmosphere: The layer of gases surrounding Earth, composed primarily of nitrogen and oxygen.
- Geosphere: The solid, rocky part of Earth, including the crust, mantle, and core.
- Cryosphere: All frozen water on Earth, such as glaciers, ice caps, and sea ice.
Types of Symbiosis
- Mutualism: Both organisms benefit from the relationship. Example: Clownfish live within sea anemones, gaining protection from predators while providing food for the anemone by attracting prey.
- Commensalism: One organism benefits, while the other is neither helped nor harmed. Example: Birds building nests in trees. The birds benefit from shelter, while the tree is unaffected.
- Parasitism: One organism benefits at the expense of the other. Example: Ticks feeding on human blood. The tick benefits, while the human may suffer health consequences.
Food Webs and Chains
- Food chains illustrate the flow of energy through a series of organisms, starting with a producer and ending with a consumer.
- Food webs are interconnecting food chains, showing the complex relationships between different organisms within an ecosystem.
Biotic and Abiotic Factors
- Biotic Factors: All living components of an ecosystem, including plants, animals, fungi, and bacteria.
- Abiotic Factors: Non-living components of an ecosystem, such as sunlight, temperature, water, and soil.

Description
Explore the fundamental concepts of Earth's spheres, including the hydrosphere, biosphere, atmosphere, geosphere, and cryosphere. Additionally, dive into the different types of symbiosis, such as mutualism, commensalism, and parasitism, with real-life examples that illustrate these relationships in nature.
