Nature’s Networks: Ecosystems & Biomes
Ecosystems and biomes study the interactions within ecosystems and explore major terrestrial and aquatic biomes, revealing how living and non-living components shape Earth’s diverse environments. Ecosystems involve organisms interacting with their surroundings, like in a forest or coral reef, while biomes are large-scale regions, such as tundras or oceans, defined by climate and species, offering insights into biodiversity and ecological balance.
Components of Ecosystems & Biomes
Ecosystems and biomes are defined by their interactions and the characteristics of major global regions. Here’s the breakdown:
- Ecosystem Interactions: Relationships between biotic (living) and abiotic (non-living) factors in an ecosystem.
- Terrestrial Biomes: Land-based biomes like forests, grasslands, and deserts, defined by climate and vegetation.
- Aquatic Biomes: Water-based biomes, including freshwater (lakes, rivers) and marine (oceans, coral reefs).
- Biodiversity in Biomes: The variety of species and adaptations unique to each biome.
Lists of Ecosystems & Biomes Components with Examples
Ecosystem Interactions Examples
- In a forest, trees (biotic) absorb sunlight (abiotic) to photosynthesize.
- Frogs in a wetland eat insects, controlling pest populations.
- Decomposers like fungi break down dead leaves, recycling nutrients.
Terrestrial Biomes Examples
- Tropical rainforest: The Amazon has high rainfall, dense vegetation, and jaguars.
- Tundra: The Arctic tundra is cold, with permafrost and caribou.
- Desert: The Sahara has extreme heat, sparse plants, and camels.
Aquatic Biomes Examples
- Freshwater: The Great Lakes host fish like trout, with clear water.
- Marine: Coral reefs in the Pacific support colorful fish and corals.
- Estuary: The Chesapeake Bay mixes freshwater and saltwater, hosting crabs.
Biodiversity in Biomes Examples
- Rainforests have high biodiversity, with species like orchids and monkeys.
- Coral reefs support diverse marine life, including clownfish and sharks.
- Grasslands feature grazing animals like bison and diverse grasses.
