Marine Habitat 1

Front 1

marine ecology

Back 1

The study of interactions of marine organisms with each other and with their environment

Front 2

Ecology

Back 2

Study of the inter-relationships between the physical and biological aspects of the environment. Study of how organisms adapt to and alter their environment

Front 3

abiotic

Back 3

temperature, salinity, pressure, nutrients, dissolved gases, currents, light, suspended sediments, substrate, river inflow, tides, and waves.

Front 4

biotic factors

Back 4

competition, predation, symbiosis

Front 5

Predation

Back 5

can affect community structure, increased diversity when superior competitor is preferred prey

Front 6

Symbiosis

Back 6

co-occurrence of two species in which the life of one is closely tied with the life of another

Front 7

Infraspecific Competition

Back 7

between individuals of the same species, leads to adaption

Front 8

Interspecific Competition

Back 8

between individuals of different species, lead to competitive exclusion

Front 9

Light penetration is different based on

Back 9

levels of photosynthesis, water quality/ sedimentation/ turbidity, & location

Front 10

Temperature can control organism life by

Back 10

distribution, degree of activity. reproduction

Front 11

Water quality parameters

Back 11

light, temperature, salinity. dissolved gases

Front 12

Pressure

Back 12

pressure changes with increases water depth

Front 13

Benthic community, Soft bottom

Back 13

soil decreases in volume, sand and mud substrates.Sandy areas harbor filter feeders whereas deposit feeders dwell in muddy regions

Front 14

Benthic community, Hard bottom

Back 14

rock and gravel substrates.Seaweeds occur here and the animals tend to be filter feeders, grazers, and predators (coral & kelp)

Front 15

Top predators in the open ocean

Back 15

squid, jellyfish, tuna, porpoise, shark, humans

Front 16

Pelagic communities

Back 16

is a community of organisms that live suspended in the water column…they either float (plankton) or swim (nekton).

Front 17

Population

Back 17

A group of organisms of the same species occupying a specific area

Front 18

Community

Back 18

Many populations of organisms that interact with each other at a particular location

Front 19

Community composition, Physical factors (abiotic)

Back 19

temperature, salinity, dessication, pressure can all limit where an organism can survive

Front 20

Community composition, Biological factors (biotic)

Back 20

larval supply, competition, predation, parasitism, can also limit where an organism can be found

Front 21

Symbiosis, Mutualism

Back 21

two organisms of different species exist in a relationship in which each individual benefits.

Front 22

Symbiosis, Commensalism

Back 22

relationship between two organisms where one organism benefits without affecting the other.

Front 23

Symbiosis, parasitism

Back 23

one organism [parasite] benefits, and the other [host] is adversely affected [weakened, sickened, damaged etc].

Front 24

Niche

Back 24

an organism’s environmental role (environmental factors, biological factors, the organism’s behavior)
