@@Mr.Smedes Yes, this is my first year teaching it. I usually teach just chem and orgo. I have started making guided note outlines to go along with some of the videos and assigning them for homework. Thanks a bunch for doing this!
Hi, thanks for the video. I have a quick question. (7:15) Do Boreal Forest (Taiga) and Tundra have fewer nutrients for similar reasons? What's the difference? I was thinking that Tundra was a more extreme case that has even fewer nutrients? Please correct me if I'm wrong.
I think the difference is that tundra has much less organisms living there so there's much less dead matters. With the cold soil, the decomposers can't absorb anything to make nutrients. In boreal forest, there's much more organisms but most of those plants are evergreen. With cold soil, there's not much nutrients. So basically tundra has low organisms and low nutrient, boreal forest has higher organisms and low nutrients.
1.2- Terrestrial (land) Biomes
Biome- an area that shares a combination of avg. yearly temp, & precipitation (climate)
The organisms that live in the biome are adapted for that biome specifically
Biome chart can predict where biome is on earth:
Tundra & boreal = higher latitude (60+)
Temperate = mid latitude (30-60)
Tropical = closer to the equator
Nutrient Availability
Availability of soil nutrients determine what plants can survive
Ex: frozen soils of tundra don't allow nutrients in dead org. matter to be broken down by decomposers
Low soil nutrients
Low water availability
Few plants survive here
Tropical RF= nutrient poor soil
Due to high competition from many diff species
Boreal Forest = nutrient poor soul
Low temp & low decomp rate of dead org. matter
temp forest = nutrient rich soil
a lot of dead organic matter + warm temp for decomposition
Shifting Biomes
Biomes shift as climate changes
Ex: warming climate will shift boreal forests further north as tundra permafrost soil melts & lower latitudes become too warm for aspen & spruce
Thank you so much! I am reviewing for my AP Exams in a couple weeks and this really helps me refresh what I know.
Thank you so much! I love environmental science, it sounds cool and fun. I have it next semester wish me luck in there:)
Awesome work! Thank you!

Thank you!
where can i access the slide?

Rainforests: nutrient-rich, with a lot of rain, and hot. If I wrong give feedback to me😉
Wrong, because it isn't nutrient rich due to competition between plants 6:16
