also known as adaptive radiation

20
What is the "10% rule" for energy pyramids?
About 10% of energy available at one level is available at the next level.
Total biomass decreases by about 10% at each successive level.
Total biomass increases by about 10% at each successive level.
The number of organisms decreases by about 10% at each successive level.
21
What is the key difference between parasitism and predation?
A predator may not catch its prey but a parasite always does
Parasites don't always hurt their hosts
A parasite doesn't actually kill it's host
Predation=short term relationship, parasitism=long term
