golden snail
– encompasses the biotic and abiotic component
in an environment, as well as their relationships and
interactions.
ecosystem

of different species in an ecosystem.
Relative abundance
Types of biodiversity
- Genetic D.
- Species D.
- Community or Ecosystem D.
- Functional D.
identifies how much resources environments
low genetic diversity to organisms in the same species and species an ecosystem has
Variety in biodiversity
Refers to the variability of different species represented in a community
Species diversity
Refers to the variation in the genes of a species of individuals
Genetic Diversity
Refers to the variety of ecosystems in a given region.
Community/ Ecosystem D.
Refers to the range of things an organism does in communities and ecosystems.
Functional D.
Variety commonly measured by counting all species in an area.
Species Richness
Manner which species behave, obtain food, and use the natural recourses.
Functional D.
describe as a linear network of links in a food
web. More detailed process.
