,3. Soil conditions
4. Biodiversity
5. Species interaction, for example, what is the predation of one species on
the other?
6. Are there any invasive species that compete for resources?
Name some of the environmental (ABIOTIC) factors that define an
ecosystem? - 🧠 ANSWER ✔✔1. Climate-averages and seasonality. For
example, rainy seasons.
2. Geology-bedrock, water, soils, topography.
3. Disturbance-Natural (tornado), human, and the scale and frequency of
such disturbances.
Name some of the environmental (BIOTIC) factors that define an
ecosystem? - 🧠 ANSWER ✔✔1. Biodiversity-what kinds of organisms live
there and in what proportion.
2. Biomass-for example, plants, wood, waste.
3. Species interactions-how the different species interact with one another.
4. Invasive or keystone species.

, What is an invasive species? - 🧠 ANSWER ✔✔An organism that is not
native to a particular area. An invasive species is capable of causing
extinctions of native plants and animals, reducing biodiversity, competing
with native organisms for limited resources, or altering habitats.
Is there any defined size for an ecosystem? - 🧠 ANSWER ✔✔No, there are
no boundaries, mostly.
Mount St. Helens - 🧠 ANSWER ✔✔Located in Washington State and part
of the Cascade Mountains. It is a part of the temperate rainforest biome.
What happens to a biome as the elevation increases? - 🧠 ANSWER ✔✔At
sea level, there is tropical rainforest, and as we go up in elevation, there is
temperate forest, then taiga, then tundra, then polar ice at the top of the
mountain.
Answer: What type of biome did Mt. St. Helen have prior to the volcanic
eruption? - 🧠 ANSWER ✔✔Old growth forest, rich soil.
*Be able to interpret graphical climate data to estimate climatic conditions.
Meaning, does the graph indicate warm/wet, seasonally hot/dry, etc. - 🧠
ANSWER ✔✔
