Study Notes
Biodiversity
- Biodiversity encompasses all the various life forms on Earth.
Classification System
- A hierarchical system categorizes organisms: Kingdom, Phylum, Class, Order, Family, Genus, Species.
Resource Partitioning
- Resource partitioning minimizes competition among species by allowing them to coexist and utilize shared resources in different ways.
Species, Populations, and Communities
- Species: Organisms with similar structures that can reproduce.
- Populations: Organisms of the same species, living in the same area, sharing resources.
- Communities: Different interacting species in a specific environment, sharing resources.
Ecosystem
- An ecosystem comprises living (biotic) and non-living (abiotic) components interacting within a shared environment.
Diversity Within and Between Ecosystems
- Within-species diversity: Variation within a single species (e.g., human skin color, eye color).
- Between-species diversity: Differences among distinct species (e.g., humans vs. fish).
Symbiotic Relationships
- Symbiotic relationships describe interactions between different species, including commensalism, mutualism, parasitism, and interspecies competition.
Natural Selection
- Natural selection favors individuals better adapted to their environment, allowing them to reproduce and pass on advantageous traits.
Variation
-
Discrete variation (discontinuous): Traits present either/or (e.g., presence or absence of a characteristic).
-
Continuous variation: Traits with a range of possibilities (e.g., height, number of freckles).
-
Between-species variation: Differences among different species.
-
Within-species variation: Differences within the same species.
