Trophic levels Flashcards
Utilizes either photosynthesis or chemosynthesis to create its own energy (Self-Foods)
Autotroph
Gains energy by eating different organisms (different food)
Heterotroph
Trophic level 1
Autotrophs- photosynthesis for energy
Primary Producers
trophic level 2
Heterotroph- herbivore
Primary Consumers
trophic level 3
Heterotroph- Omnivores, carnivores
Secondary consumers
trophic level 4
Carnivores
Tertiary consumers
Trophic level 5
Top level carnivores
Quaternary Consumers
10 % rule
only 10% of energy is transferred to next trophic level, the other 90% is lost as heat!
if producers have 100% available energy, how much remains in other levels
P.C=10%
S.C=1%
Third level c.=.1%
Apex pred=.01%
The amount of living matter in an ecosystem
EX: highest amount is producers, lowest is highest level consumer
Biomass
Changing calories up the trophic pyramid due to 10% rule
100,000 kcal- Producers, 10,000 kcal primary consumers, 1000 kcal secondary consumers, 100 kcal tertiary consumers and 10 kcal quaternary consumers.
The study of how organisms interact with each other and the environment
Ecology
An intricate ecosystem of organisms that shows energy transfer with an arrow producers→ consumers
Food web
A single organism to organism energy transfer
Food chain
