Producers/Autotrophs (either or)
What are the levels of ecological organization from largest to smallest. (There are 6)
Biosphere
Biome
Ecosystem
Community
Population (Species)
Organism

What is an ecosystem?
A herbivore would be a ____________ consumer.
Primary
Non-living factors that play a role in the survival of species within an ecosystem
Abiotic
Evaporation, Condensation, Precipitation
Identify the relationship:
Plover birds feed on the decay and bacteria found within the mouths of crocodiles
Mutualism
The pioneer species that usually begins primary succession by breaking down rock.
Lichen
Because energy is used and lost as heat, what percentage of energy is usually passed between trophic levels?
10%
Omnivore
What two processes do consumers and producers perform to recycle carbon back and forth?
photosynthesis and respiration
Identify the Relationship:
A tick latches on to a dog, and feeds by sucking its blood.
Parasitism
An organism that breaks down wastes and dead organisms, and returns their nutrients back to the soil
A model used to show how energy is dispersed within an ecosystem
Ecological Pyramid
The role that a species plays within an ecosystem is said to be its....
Niche
The additional CO2 added to the atmosphere is not only depleting the ozone layer, but also causing this phenomona to occur that is heating the planet
Greenhouse Effect
The organism that is hurt by a parasitic relationship...
Host
Each step in a food chain or ecological pyramid
Trophic Level
If 90,000 calories are produced in an ecosystem, how much energy is LOST by the time the the tertiary consumer is reached? (You have 45 seconds)
89,910
81,000 used by producers + 8,100 used by 1st consumers + 8100 used by 2nd consumers = 89,910 calories lost
