Study Notes
Biological Diversity and Interdependence
- The Amazon Rainforest's warm temperatures and ample sunlight support year-round plant growth
- Species distribution is not uniform across the Earth, with less diversity towards the poles
- There are an estimated 8.7 million plant and animal species, but only 1.2 million have been identified
- Biological diversity encompasses genetic, species, and ecosystem diversity
- Biological diversity is important for ecosystem stability, including disease resistance and adaptation
- Variability within species is crucial for survival in changing environments
- Natural selection is the process by which the environment determines survival, while artificial selection involves intentional breeding for desirable traits
- Carolus Linnaeus developed a system for classifying organisms based on physical structure
- Modern scientists expanded Linnaeus' system into the 5 kingdom classification: Animalia, Plantae, Fungi, Protista, Monera
- Interdependence among species is essential for survival and includes symbiotic relationships, competition, and predator-prey dynamics
- Symbiosis includes commensalism (one benefits, the other is unaffected), mutualism (both benefit), and parasitism (one benefits, the other is harmed)
- Examples of symbiosis include birds nesting in trees (commensalism), lichen in the arctic tundra (mutualism), and tapeworms in the human intestine (parasitism)
