Energy & Matter
The process that turns sunlight, CO₂, and water into glucose.
What is photosynthesis?
A relationship where both species benefit.
What is mutualism?
The maximum number of individuals an environment can support.
What is carrying capacity?
Succession starting in areas without soil.
What is primary succession?
The cycle that moves water through evaporation, condensation, and precipitation.
What is the water cycle?
The group of organisms that make their own food.
What are producers (autotrophs)?
A species with a disproportionately large effect on its ecosystem.
What is a keystone species?
A J-shaped growth curve represents this type of growth.
What is exponential?
Succession starting where soil already exists.
What is secondary succession?
The greenhouse effect is caused by these.
What are greenhouse gases?
The pyramid that shows energy transfer between trophic levels.
What is an energy pyramid?
A relationship where one benefits and the other is harmed.
What is parasitism?
Growth that slows near carrying capacity.
What is logistic growth?
The ability to recover after a disturbance.
What is resilience?
Nitrogen fixation is primarily carried out by these organisms.
What are bacteria?
The process that releases CO₂ when glucose is broken down.
What is cellular respiration?
Symbiosis where one benefits and the other is unaffected.
What is commensalism?
The formula r = b – d represents this.
What is per capita growth rate?
The ability to remain unchanged during a disturbance.
What is resistance?
Fossil fuels are formed through this process.
What is fossilization?
The majority of energy is lost at each trophic transfer as this.
What is heat?
What is an endemic species?
A survivorship curve where many offspring die young.
What is Type III?
The hypothesis that biodiversity is highest at moderate disturbance.
What is the intermediate disturbance hypothesis?
Nutrient pollution often leads to this event in aquatic ecosystems.
What is eutrophication (algal blooms)?
