Study Notes
SVT - Ecology
- Ecology: the scientific study of relationships between living things and their environment.
- Environment (milieu): The surroundings.
- Species counting: Regular sampling over time.
- Scientific photos: Important for accurate data.
- Coral role: Protection against erosion and carbon dioxide storage.
Biodiversity
- Biodiversity: the variety of living things.
- Three levels:
- Ecosystem diversity: variety within an environment.
- Species diversity: variety of species within an ecosystem.
- Genetic diversity: variety within a species.
- Definitions evolve over time.
Food Webs
- Food web: a chain of feeding relationships.
- Hybrid: the result of crossing two species.
Microbiology
- API test: Identifying bacteria types by placing them in various environments.
- Code of numbers: Results of the test
- Prokaryotes: Lack a nucleus.
- Eukaryotes: Have a nucleus.
Species and Characteristics
- Species: A tool for describing biodiversity, based on:
- Morphology: Physical characteristics.
- Genetics: Hereditary traits.
- Metabolism: Chemical processes.
- Reproduction: How species make more of themselves.
- Phenotype: An observable characteristic determined by genes.
- Genotype: All the genes in an organism, which together determine an inherited trait.
Alleles and Inheritance
- Dominant allele: An allele that is expressed more frequently than others.
- Recessive allele: An allele that's only expressed when paired with another recessive allele.
- Advantageous alleles: Increases survival and reproduction traits in an organism.
Fossils
- Fossils: Mineral remains or impressions of past organisms that provide evidence of previous biodiversity.
