Guide- Unit 1 Test
10%rule - correct Answer-As you go up, the food chain. 90% is lost and 10% goes up.
-On average pnly 10% of the energy from a lower level makes it to the level above.
Abiotic Factors - correct Answer-Non-living thing
Ex: Waters, soils, minerals in the soil,O2
Biodiversity - correct Answer-Why is it valuable? Makes the ecosystem stronger. The
richer it is, the higher the diversity is. Biodiversity contain species and genetic diversity.
Species diversity: The # of different types of species in an ecosystem.
Genetic Diversity: The variety of genetic diversity held within a species.
Species richness: The # of species
Species Eveness: The relative # of species
Biomagnification - correct Answer-Toxic substances become increasingly concentrated
withn living organisms as they move up each step of the food chain.
*The more you go up the food chain, the more toxins you have in your body.*
Biomass - correct Answer-The mass of the living thing
Biotic Fctors - correct Answer-Living things
Ex: Grasses, elephants
Climax Community - correct Answer-Fully recover ecosystem
Community - correct Answer-Living things in an community. Groups of different species
living together in a particular place with a potential for interacting with one another.
Example:Deer
Competition - correct Answer-Neither organisms is happy about this
Ecological Succession - correct Answer-A process of ecosystem recovering
Ecosystem - correct Answer-Living and non-living things
Example: Rock, deer
Ecosystem Services - correct Answer-a) What products do we get from the healthy
ecosystem?
b) What life functions we get from the healthy ecosystem?
