Biology Vocab Review Flashcards
An ecological relationship in which two species live in close contact with each other.
Symbiosis
The functional position of an organism in an environment. This could be how it adapts, what it responds to, or how it lives.
Niche
A fundamental unit of structure and function, collection of molecules and organelles. You are made of trillions…
Cells
A region or area that includes BOTH living and non-living things…
Ecosystem
Living organisms.
Biotic
A natural environment where an organism lives and thrives.
Habitat
When an organism gains something in a relationship but the other suffers or loses something. Usually, the organism suffering does not die in this case.
Parasitism
The suffix -troph or the word Trophic refers to the action of… (Think about Heterotroph)
Eating
Non-living things.
Abiotic
Which of these definitions defines a relationship where one species benefits and the other does not benefit NOR does it suffer? A good example would be whales and barnacles that hitch a free ride on the Whale’s skin but causes no extra burden to the animal.
Commensalism
Evolution is…
A commonly accepted theory that organisms change overtime due to evidence and data to back it
When an organism gains from a relationship and the other is killed and eaten for energy gain.
Predation
A signal in which an organism responds. This could be water, temperature, sunlight, or introduction of a new organism.
Stimuli
Species or organism that has a unique and vital role in maintaining structure, stability, and diversity in an ecosystem. (example: wolf, beaver)
Keystone species
Individuals of the different species compete for the same limited limited resources. This could be a blue jay and a cardinal competing for seeds.
Interspecific Competition
individuals of the same species compete for the same limited limited resources
Intraspecific competition
A collection of molecules that work together for a specific function, working components of a cell.
Organelles
The maximum number of organisms an area/environment can support.
Carrying Capacity
The variable that does not change between trials in order to have accurate/reliable data.
Control variable
An organism that CAN NOT produce it’s own food. It must obtain energy from something other than itself, one of which most likely used to be living.
Heterotroph
The study of living things and their relationships
Biology
A chemical structure consisting of two or more atoms.
Molecule
The data-based variable in an experiment that is being recorded and is usually shown on the Y axis of a graph.
Dependent variable
A body part made up of multiple tissues working together
Organ
The theory that specific organisms are physically and genetically fit to survive in a specific environment.
Natural selection
A relationship where both organisms benefit from the situation.
Mutualism
The manipulated variable in an experiment.
Independent Variable
A large community of plants and animals that occupies a distinct region of Earth.
Biome
Which of the following will eat plant and organism based diets?
Omnivore
The use of EVIDENCE to construct TESTABLE explanations and predictions of natural phenomena.
Science
