New cards
Primary Productivity
Rate producers convert sunlight into biomass
3
New cards
Gross Primary Productivity (GPP)
Total energy captured by producers
4
New cards
Net Primary Productivity (NPP)
GPP minus respiration
5
New cards
Food Chain
Linear transfer of energy
6
New cards
Food Web
Multiple interconnected food chains
7
New cards
Trophic Level
Feeding position in a food chain
8

Primary Producer
Makes its own food
9
New cards
Primary Consumer
Herbivore
10
New cards
Secondary Consumer
Eats herbivores
11
New cards
Tertiary Consumer
Eats secondary consumers
12
New cards
10% Rule
About 10% of energy transfers to next trophic level
13
New cards
Why Food Chains Are Short
Energy is lost at each trophic transfer
14
New cards
Factor Determining Food Chain Length
Productivity and energy transfer efficiency
15
New cards
Why Aquatic Food Chains Are Longer
Phytoplankton are consumed efficiently
16
New cards
Why Terrestrial Food Chains Are Shorter
More energy trapped in plant tissue
17
New cards
Keystone Species
Species with disproportionately large ecosystem effects
18
New cards
Trophic Cascade
Changes at one trophic level affect all others
19
New cards
Yellowstone Wolf Example
Wolf reintroduction increased biodiversity
20
New cards
Effect of Reintroducing Keystone Species
Usually increases biodiversity
