Section 1 Flashcards
Productivity
the amount of food produced by marine organisms and the number of organisms the ocean can support
Oceanography
the study of the ocean and their phenomena
Marine Biology
the study of organisms and their reactions with each other and their environments
Inductive Reasoning
involves looking at individual observations and proposing a general explanation for them
Deductive Reasoning
the process of reasoning whereby observations suggest a general principle from which a specific statement can be derived
Theory
a body of observations that have stood the test of time
Experimental Variable
factor that is altered in an experiment
Experiment Set
has experimental variable
Control Set
without experimental variable
Observational Science
observing and describing and possibly theorizing; but not testing
Aristotle
the first to develop scheme of classification “ladder of life”
Pliny the Elder
roman naturalist; works in natural history
Kumulipo
hawaiian creation chant
Jean-Baptiste Lemark
environment shapes animals, forms vs function
George’s Cuvier
“father” of vertebrate paleontology
Charles Darwin
HMS beagle 1831 observations of atolls, 1859 origin of the species by natural selection
Modern Science Originated…
in the challenger expedition, 19th century
First Marine Bio Lab…
Louis Agassiz started a lab for teachers in 1873
Scientific Method (1)
making observations
Scientific Method (2)
using inductive reasoning to form a hypothesis
Scientific Method (3)
using deductive reasoning to design experiments
Scientific Method (4)
gathering results
Scientific Method (5)
drawing conclusions
70% of the Ocean affects (3)
global issues, provides food and vital resources, helps understand/ relate to organisms and how we affect them
Zones of Intolerance
regions where an environmental variables is so far from optimal range that the organism cannot survive
Ecosystem
system composed of living organisms and their physical environment
Biosphere
composed of all the earths ecosystems; all are interconnected
Environment
consists of all the external factors acting on that organism
Abiotic Factors
physical factors; temperature, salinity, pH, sunlight
Biotic Factors
biological factors; living organisms, and their interactions with each other( plants and animals)
Habitat
where an organism lives, specific place where an organism is found
Microhabitat
smaller subdivisions of a habitat
Homeostasis
International steady state of a cell or an organism
Optimal Range
range of environmental factors to which an organism is best adapted
Zones of Stress
Regions above and below the optimal range of environmental variables
Phytoplankton
photosynthetic organisms (mostly microscopic plantlike organisms and bacteria) that float in the sea currents
Ectotherms
animals that obtain most of their body heat from the environment
Endotherms
animals that obtain most of their body heat from metabolism
Metabolism
the sum of all the chemical reactions that occur within cells
Salinity
a measure of the concentration of dissolved inorganic salt in water
Solutes
substance is dissolved in water
Osmosis
movement of water across a semipermeable membrane from an area of low salute concentration to an area of high salute concentration
Sunlight
a central role in the marine environment; powers photosynthesis
