Study Notes
Definition of Habitat
- A habitat is the natural environment in which an organism lives, including living and non-living factors.
- It is the specific area where an organism can find food, shelter, and protection from predators.
Components of a Habitat
- Biotic factors: living components, such as plants, animals, and microorganisms.
- Abiotic factors: non-living components, such as temperature, humidity, light, water, soil, and air.
Types of Habitats
- Terrestrial habitats: land-based habitats, including forests, grasslands, deserts, and tundras.
- Freshwater habitats: habitats found in freshwater ecosystems, such as rivers, lakes, and wetlands.
- Marine habitats: habitats found in saltwater ecosystems, such as coral reefs, estuaries, and open ocean.
- Arctic and alpine habitats: habitats found in cold, treeless regions, such as tundras and mountain tops.
Importance of Habitat
- Supports biodiversity: habitats provide a home for a wide range of species, allowing them to coexist and thrive.
- Provides resources: habitats supply organisms with food, water, shelter, and other essential resources.
- Influences behavior: habitats can shape the behavior and adaptations of organisms that live within them.
Habitat Destruction and Fragmentation
- Habitat destruction: the process of destroying or altering a habitat, making it unable to support the organisms that live there.
- Habitat fragmentation: the process of breaking up a habitat into smaller, isolated areas, making it difficult for organisms to move and interact.
Habitat Definition and Components
- A habitat is the natural environment where an organism lives, comprising living (biotic) and non-living (abiotic) factors.
- Biotic factors include plants, animals, and microorganisms, while abiotic factors include temperature, humidity, light, water, soil, and air.
Types of Habitats
- Terrestrial habitats are land-based, including forests, grasslands, deserts, and tundras.
- Freshwater habitats are found in rivers, lakes, and wetlands.
- Marine habitats are found in saltwater ecosystems, including coral reefs, estuaries, and open ocean.
- Arctic and alpine habitats are found in cold, treeless regions, including tundras and mountain tops.
Importance of Habitat
- Habitats support biodiversity by providing a home for a wide range of species, allowing them to coexist and thrive.
- Habitats supply organisms with essential resources such as food, water, shelter, and other necessities.
- Habitats shape the behavior and adaptations of organisms that live within them.
Habitat Destruction and Fragmentation
- Habitat destruction is the process of destroying or altering a habitat, making it unable to support the organisms that live there.
- Habitat fragmentation is the process of breaking up a habitat into smaller, isolated areas, making it difficult for organisms to move and interact.
