Adaptation, Interdependance And Competition Flashcards
(20 cards)
An abiotic factor is…
Non-living chemical and physical part of the environment that affect living organisms and the functioning of ecosystems.
An abundance is…
A measure of how common or rare a particular type of organism is in a given environment.
Adaptations are…
Special features that make an organism particularly well suited to the environment where it lives.
A biotic factor is…
Any living component that affects another organism, i.e. a living thing that helps shape an ecosystem.
A community is…
A group of interdependent organisms living in an ecosystem.
Competition is…
The process by which living organisms compete with each other for limited the sources such as food, light, or reproductive partners
Distribution is…
Where particular types of organisms are found within an environment.
An ecosystem is…
A community of living organisms together with the nonliving components of their environment, interacting as a system.
Extremophiles are…
Organisms that can survive and reproduce in extreme conditions.
A habitat is…
Ecological or environmental area inhabited by a particular species; natural environment in which an organism lives, or the physical environment that surrounds a species population.
Interdependence is…
The network of relationships between different organisms within a community. For example, each species depends on the other species for food, shelter, pollination, seed dispersal etc.
The mean is…
The arithmetical average of a series of numbers.
The median is…
The middle number in a list of numbers.
The mode is…
The number which occurs most often in a set of data.
A quadratic is…
A sample area are used for measuring the abundance and distribution of organisms in the field.
Quantitative sampling is where you…
Record the number of organisms rather than just the type.
The population is…
A group of organisms of the same species inhabiting a given area.
The range is…
The maximum and minimum values for independent or dependent variables - important in ensuring that any patterns are detected.
A sample size is…
The size of the sample in an investigation.
Transect is…
A measured line or area along which ecological measurements are made.
