Study Notes
Ecology
- Study of the relationships between living organisms and their environment
- Examines the interactions between organisms and their physical environment (e.g. climate, soil, water)
- Focuses on the dynamics of populations, communities, and ecosystems
Key Concepts:
- Biotic factors: living components of an ecosystem (e.g. plants, animals, microorganisms)
- Abiotic factors: non-living components of an ecosystem (e.g. light, temperature, water)
- Ecosystem services: benefits provided by ecosystems (e.g. air and water purification, soil formation)
- Food webs: networks of predator-prey relationships in an ecosystem
- Energy flow: movement of energy from one trophic level to the next in an ecosystem
Genetics
- Study of heredity, genes, and genetic variation
- Examines the transmission of traits from one generation to the next
- Focuses on the structure and function of genes and genomes
Key Concepts:
- DNA: double-stranded molecule containing genetic information
- Genes: units of heredity that carry information from one generation to the next
- Genotype: genetic makeup of an individual
- Phenotype: physical and behavioral characteristics of an individual
- Mendel's laws: principles of inheritance discovered by Gregor Mendel (e.g. segregation, independent assortment)
Evolution
- Study of the changes in the characteristics of populations over time
- Examines the processes that shape the diversity of life on Earth
- Focuses on the adaptation of populations to their environment
Key Concepts:
- Natural selection: process by which populations adapt to their environment
- Speciation: formation of new species
- Adaptation: trait that increases an individual's fitness in a given environment
- Fossil record: chronological record of the history of life on Earth
- Homologous structures: structures shared between different species that have a common evolutionary origin
Explore the basics of biology, covering the relationships between living organisms and their environment, the study of heredity and genetics, and the changes in populations over time.
