ECOSYSTEM
Organization structure that builds biosphere
(1) Biosphere
(2) Biome
(3) Ecosystem
(4) Community
(5) Population
(6) Individual
Freshwater
Lake
River
Pond
Land
Savana
Tropical
Rainforest
Desert
Taiga & Tundra
Marine
Ocean
Sea
All ecosystems that exists
Earth
Component of ecosystem
BIOTIC
Producer
Plants photosynthesize to produce food
Consumer
Animals that eat plants/other animals
ABIOTIC
Interaction between ecosystem
Symbiosis
Mutualism
Both organisms benefit
Parasitism
One organism benefits and one is harmed
Commensalism
One organism benefits and one does not benefit but is unharmed
Amensalism
One organism causes harm to another organism without any cost or benefits to itself

Feeding
Plants, animals, and decomposers continually recycling the same nutrients through the ecosystem
Neutralism
Interactions between the two individuals are neutral in regards to both species
Competition
Animals compete for food, shelter, mates, nesting sites
Plants compete for CO2, mineral ions, light and water
Between ORGANISM & ENVIRONMENT
Plants absorb mineral ions, CO2, water from environment
Plants give off water vapor & O2
Animals use materials from environment to build shelters
Food chain, Food web,
Pyramid of Ecology
Pyramid of Ecology
Pyramid of numbers
The numbers of organisms in each trophic level in a food chain (irrespective of their mass)
Pyramids of biomass
Total mass of organisms in each trophic level (irrespective of their numbers)
Decomposer
Organisms that break down dead materials
Recycle nutrients
Food Chain
Consists of producer
and consumer
Primary consumer
Secondary consumer
Tertiary consumer
Quartenary consumer
Food web
Consists of ALL the food chains
in a single ecosystem
Physical Environment
Non-biological components
