Unit 1
what is the relationship that benefits both organisms
Mutualism
what is the term used for
just the total number of different
species found in an ecosystem
Species Richness
what are the 3 types of plate boundaries
divergent <>
convergent ><
TranSform (slide past each other)
Name 6 different types of terrestrial Biomes and which one is the most biodiverse.
rain forest, tiaga, temperate deciduous forest, tundra, desert and grasslands
Tropical rain forests are the most biodiverse
What is the THEORY of ISLAND Biogeography. Hint: we did a lab based on this theory and we created little and big islands in the classroom.
Larger islands and islands closer to the mainland support more species therefore are more biodiverse
What are the layers of the earth
Core, mantle (magma, asthenosphere, lithosphere) and crust
What are the 4 characteristic that help identify the different types of aquatic biomes.
salinity, flow, temperature and depth
based on the 10% rule how much percent of energy is available for tertiary consumers.
.1%
what are the 4 soil horizons and which one has the most organic material
In order
o-horizon
a-horizon (most nutrients)
b-horizon
c-horizon
What are the major sources of CARBON.. refer to the carbon cycle
The ocean is the biggest carbon sink other sources are fossil fuels, animal agriculture mainly cow farts and burps and deforestation
An env. disturbance (natural disaster/human hab. destruction) that drastically reduces
pop. size & kills organisms regardless of their genome
Bottleneck event
What are the three characteristics used to identify a soil type?
Particle size, texture and porosity
name the steps of the nitrogen cycle in order
Nitrogen fixation , assimilation, ammonification, nitrification and lastly denitrification.
What are the 4 ecosystems services and what do they provide
Provisioning Goods taken directly from ecosystems or made from natural
resources (wood, paper, food)
Regulating Natural ecosystems regulate and stabilize climate, air quality, water quality soil, biodiversity
Supporting Natural ecosystem processes that sustain ecosystems & allow
them to support life
Cultural Money generated by recreation (parks, camping, tours) or
scientific knowledge
Based on the soil texture chartk, what type of soil do I have within 40% sand, 40%silt and 20% clay
