Study of the interactions of organisms with each other and their environment
What is ecology?
Non-living factors like temperature, salinity, pH, dissolved oxygen, light, etc.
What are abiotic factors?
Species evolve in response to each other
What is coevolution?
Organisms living very closely together
What is symbiosis?
Can be photosynthetic or chemosynthetic
What are autotrophs?
Growth that is represented by J-curve
What is exponential growth?
Short supply restricts population growth
What is a limiting resource?
_% of energy is lost at each transfer as heat
What is 90?
Population growth that occurs until resources become limited
What is logistic growth?
Competition that occurs between members of different species
What is interspecific competition?
Are the basis of food chain in hydrothermal vents
What are bacteria?
Climate change and overfishing are examples of this
What are human impacts on marine ecology?
An organismβs position on the food chain
What is a trophic level?
_ explains why food chains are relatively short
The largest population size that can be sustained by available resources
What is carrying capacity?
The symbiont benefits, and the host neither benefits nor is harmed
What is commensalism?
Shrimp eating parasites/dead skin off larger fish is an example of this
What is mutualism?
Are the basis of food chain in all marine areas (except hydrothermal vents)?
What are diatoms?
Modern COβ levels have reached _ ppm
What is 400?
Energy is recycled by these kinds of organisms
What are decomposers?
Ecological interactions affect _ and _ of organisms
What are abundance and distribution?
Pelagic zone that is found closest to the surface
What is the epipelagic zone?
5 subdivisions of heterotrophs
What are herbivores, carnivores, omnivores, scavengers, and detritivores?
Pelagic zone that is found on top of a continental shelf
What is the neritic zone?
Hadal and hadopelagic zones are found here
What are trenches?
