Topic 1 Flashcards
Genetic Composition
the specific set of genes that make up an organism, like the instructions inside our DNA that decide things like how we look or how our bodies work.
Taxonomic Units
a group used to classify living things. For example, species, genus, and family are all taxonomic units.
Difference between Character and Trait
Character: A heritable feature of a given organism
Trait: A specific state of the character
Four Benefits of Biodiversity
- Provision of materials
- Regulating Services
- Supporting Services
- Cultural Services
Difference in Extinction and Extirpation
Extinction is the last individual is still living.
Extirpation is the local extinction of a species in a certain area, but its populations can be found in other locations.
Habitat Loss
Natural environments become unable to support the local species.
Invasive Species
A species, often introduced by humans, that takes hold outside its native range.
Overexploitation
Harvesting of wild plants or animals at rates exceeding the ability of populations of those species to recover.
Global Climate Change
Significant, long-term changes in the patterns of temperature, precipitation, wind, and other aspects of Earth’s Climate.
Define the three main components of biodiversity
- Species Diversity: Number of species or higher taxonomic units
- Genetic Diversity: Various Versions of genetic composition within and among populations of a single species
- Ecosystem Diversity: The variety of habitats and the relationship among them.
