Study Notes
Key Vocabulary and Definitions
- Species: A group of organisms with shared traits, capable of interbreeding to produce fertile offspring.
- Biological Diversity: The variety of life forms, encompassing species, genetic, and ecosystem diversity.
- Kingdoms of Life: Five classifications: Animalia, Plantae, Fungi, Protista, and Monera.
-
Symbiotic Relationships: Interactions between species:
- Mutualism: Both species benefit.
- Commensalism: One species benefits, the other is unaffected.
- Parasitism: One species benefits at the expense of the other.
Core Concepts
- Classification System: Organisms are categorized hierarchically (Kingdom → Phylum → Class → Order → Family → Genus → Species).
- Niche: An organism's role in its ecosystem, including habitat, diet, and interactions with other species.
-
Variation:
- Genetic Variation: Differences in DNA between individuals.
- Heritable Traits: Traits passed from parent to offspring (e.g., eye color).
- Discrete Variation: Traits with distinct categories (e.g., blood type).
- Continuous Variation: Traits varying along a spectrum (e.g., height).
Biological Processes
- Asexual Reproduction: Reproduction involving one parent, producing offspring with identical traits. Examples include budding, binary fission, and spore production.
- Sexual Reproduction: Reproduction involving two gametes (specialized cells). The union of sperm and egg (fertilization) leads to genetic variation.
- Natural Selection and Adaptation: Species with greater variation are better equipped to adapt to environmental changes. Natural selection favors individuals most suited to their environment.
- Antibiotic Resistance: Overuse of antibiotics promotes resistant bacteria through natural selection.
Ecological Interactions and Relationships
-
Symbiosis Examples:
- Goby fish and shrimp: Mutualistic relationship.
- Barnacles on whales: Commensalistic relationship.
- Food Web Roles: Organisms play roles as producers, consumers, or decomposers.
- Human Influence and Conservation: Protecting biodiversity is essential for ecosystem stability. Avoiding resource overuse is crucial to prevent species extinction.
Application Concepts
-
Experimental Design:
-
Variables:
- Manipulated Variable: The factor changed in an experiment (e.g., fertilizer type).
- Responding Variable: The observed effect (e.g., plant growth).
- Data Interpretation: Using graphs and tables to analyze patterns in species diversity and environmental impacts.
-
Variables:
- Ecological Impact: Changes in predator or prey populations have cascading effects on ecosystems (e.g., decreased wolves lead to increased elk and reduced vegetation).
Study Tips
- Understand key terms (species diversity, niches, reproduction types).
- Review classification hierarchies.
- Practice questions related to symbiosis, reproduction, and variation.
- Visualize concepts with diagrams (e.g., food webs, reproductive processes).
- Connect concepts to real-world issues (conservation, antibiotic resistance).
- Utilize AI for concept clarification and practice questions.
