questions
1. Define and give 2 examples of a biological hotspot.
2. How are the three types of savannas (edaphic, derived, climatic) different?
3. Why is the Atacama the driest non-polar desert?
4. What are 3 ways to remove invasive plant species?
5. If you are MattChina, what the heck is up with your signature??


answers
1. Tropical Andes and Mediterranean Basin
2. The way they are formed
3. Ocean currents, dry winds, rain shadow effect
4. prescribed fire, herbicides and flooding
5. moisty *slurp slurp

For the first one, I did say define but ok.
I know stuff about rocks, minerals, experiments, and ecosystems, yay!
Now I kind of know stuff about amphibians, reptiles, weather, fossils, and water... hopefully I'll get to keep learning.

Answers
1. Grasslands in Africa? Not sure how specific my answer should be...
2. Mag: Harmful chemicals increase in concentration as one moves up a food chain
Accum: Harmful chemicals build up in a single organism
Turb: Organisms loosen the soil
Rem: Organisms are used to clean up the environment
3. Mollisols have a dark, fertile surface horizon
4. a) Fresh: heart stops, oxygen depleted, discoloration starts
b) Bloat: Anaerobic organisms give off gases, body looks bloated
c) Active decay: Most decomposition, fluids purged from body
d) Advanced decay: decomposition slows down, less nutrients
e) Dry/remains: only dry skin and bones

Sure, for number 3 i meant the soil horizon like oebacr or something but its fine, so your turn.
