Study Notes
Habitat and Niche
- Habitat refers to the natural environment where organisms like animals and plants live.
- Niche defines the specific role an organism plays within its ecosystem, including its use of resources and interactions with other organisms.
Symbiosis
- Symbiosis encompasses close, long-term interactions between different biological species.
- Types of symbiotic relationships include mutualism, commensalism, and parasitism.
Mutualism
- Mutualism is a relationship where both organisms involved benefit.
- Example: Bees and Flowers - Bees consume nectar and simultaneously pollinate flowers, aiding in reproduction.
- Example: Alligators and Birds - Birds clean the teeth of alligators while feeding on the residual food.
- Example: Clownfish and Sea Anemone - Clownfish seek shelter in anemones for protection; in return, they clean the anemones.
Commensalism
- Commensalism involves a relationship where one organism benefits and the other remains unaffected.
- Example: Remora and Sharks - Remoras attach to sharks for protection and feed on leftover scraps.
- Example: Elephants and Birds - Elephants offer shade and safety from predators to birds.
- Example: Cattle Egrets and Livestock - Cattle egrets follow livestock to consume insects disturbed by their movement.
Parasitism
- Parasitism is a relationship in which one organism benefits at the expense of another, causing harm.
- Example: Mosquitoes - Mosquitoes draw blood from other organisms, sometimes transmitting diseases.
- Example: Parasitic Worms - These worms live in hosts, consuming nutrients and hindering the host's nutrient absorption.
- Example: Ticks - Ticks feed on the blood of their hosts, potentially transmitting diseases like Lyme disease.
