Basic Terms
The study of how abiotic and biotic things interact in an ecosystem.
What is ecology?
No limiting factors. Population can grow without limit. Fast, unlimited and constant growth rate making a "J" curve.
What is exponential growth?
Living together or an organism that is at least benefited once.
The predictable series of species replacements after an ecosystem responds to disturbance. An event that happens which leads to the ecosystems population after that event.
What is ecological succession?
An organisms specific job in an ecosystem
What is niche?
Living and non-living
What is biotic and abiotic
Limited growth. Population grows quickly, slows, and then levels out to carrying capacity. "S" curve.
What is logistic growth?
Predator kills and eats prey
What is predator/prey?
First organisms
What is pioneer species
Concentration of toxins increase up the food chain
What is biomagnification?
Abitoic and biotic things that LIMIT a population's growth. When limiting factors are low, competition increases.
What is limiting factors?
A deer's population goes above the carrying capacity and then quickly goes back down to carrying capacity. This is an example of what and happened because...
What is overshoot which occurs because of an increase of prey and then a increase of mass death?
Both organisms benefit
What is mutualism?
Final, stable, and complex
What is climax community?
Must eat to get food.
What is heterotrophs/consumers?
Determined by limiting factors. The max population that an ecosystem can support.
What is carrying capacity?
Plant growth is constant. No limiting factors at the time.
What is exponential growth?
One organism benefits, the other is unaffected
What is commensilism?
After an event that leaves no soil
What is primary succession?
Make their own food
What is autotrophs/producers?
When a population breaks the carrying capacity but then suddenly drops back down to the carrying capacity because of a mass death.
What is overshoot?
Plant growth is fast, but then slows down, and finally reaches carrying capacity
What is logistic growth?
What organism in benefited, the other is harmed
What is parasitism?
After an event that leaves soil
What is secondary succession?
DAILY DOUBLE
On which trophic level would you find organisms that use the sun's energy directly to make their own food?
What is trophic level 1
