Biodiversity
The variety in life
Genetic diversity
The diversity of genetic characterists within a species
Species Diversity
The number, and density of number of a species, in a given area
Ecosystem Diversity
The diversity of ecological processes, habitats and communities
Hypothesis
A testable statement about something you think is occurring in the natural world- IF
Test
The methods of your experiment - And
Expectation
Is a statement about what you expect your data to look like if your hypothesis is correct. - Then
Biotic
The living componets of an ecosystem
Abiotic
The non-living componetns of an ecosystem
Individualistic
A chance assemblage of different species occurs in a location because of similar abiotic requirements or limitations
Interactive
Closely linked species joined by a mandatory biotic interactino and therefore must live together
Trophic levels
Levels in an ecosystem compirsed of organisms that share the same function in the food chain and the same nutritional relationhship to the primary sources of energy
What are the differnt names in the Basic Trophic Pyramid?
Abiotic Factors, Primary Producers, Herbivores, Small Carnivores, Large Carnivores.
Ecosstems
Are made up of different species and popoulations, interactions between bitoic factors, all abitioic factors, interactinos of between abiotic factors and interactions between biotic and abiotic factors in a specific area.
Communities
Are made up of the biotic factors in an ecosystem and interactions between them
Intraspecfic
Interactions between the same species
Interspecfic
Interactions between differnt species
Commensalism
Occurs when one organism benefits from the relationshiop and the other is not harmed.
Mutualism
Both parties benefit from the relationship.
Parasitism
Beneficial to one species and detrimental to the other
Predation
When one animal is highly benefited and the other animal gets highly detrimental affects (usually death)
Herbivory
When an animal feeds on a plant
Competition
When two species compete to obtain the same limited resource at the same time preventing the coexistance of both species.
Niche
(ecology) the status of an organism within its environment and community (affecting its survival as a species)
Fundamental Niche
The full potential range of the physical, chemical, and biological factors a species can use if there is no competition from other species. Can live.
Realized Niche
Part of a species fundamental niche that it actually uses, limited by competition. Does live.
Keystone species
Species that have a larger effect on their enviroment compared to other specis in their community.
Autotrophs
Produce their own food from solar energy
Chemotrophs
Produce their own food from chemical energy
Heterotrophs
Obtain food by eating other organisms or decaying matter
What are major threats to biodiversity
Invasive Species, Land use changes, OVerexploitation, Climate change.
Native Species
A species that originated in or migrated to a region as a result of natural processes. A species that developed, occurs naturally, or has existed in an area for many years
Exotic/non-native species
A species that is living outside of its native range that has arrived there due to human activity. They can have a neutral, beneficial or negative effect
Habitat loss can occur due to:
Urbanization, Resources exraction, Water projects, Mining, Deforestation, Pollution,climate change
Edge effects
Influences of adjacent habitat on edge habitat, resulting in an enviromental difference betweeen the edge and the interior
Invasive species
When a species cause the lost of another species. Reproduce quickly
Edge
The portion of an ecosystem near its perimeter
Direct use of good values
Food, Fiber, Fuel, Medicine, Building material
Indirect use vaule
Atmospheric and climate regulation, Pollination, Cultural, Spiritual,
Non-Use Values
Potential
