v1 v2 1 1 == 6.2 Edit groups == 2 The first task in building an Ecopath model is to define the model’s functional groups (called Groups or Boxes). Groups are species or collections of species that share similar population dynamics and ecological function. See [ [Defining the system.htm|Defining the system]] for more on how to define groups.2 The first task in building an Ecopath model is to define the model’s functional groups (called Groups or Boxes).

See [wiki:EwEugDefiningTheSystem Defining the system] for more on how to define groups. 3 3 4 To add and edit functional groups to an Ecopath model, choose the ''Edit groups...'' option on the [ [Ecopath menu.htm|Ecopath menu]] on the ''Menu bar''. This will open a form where you can add, delete, name and sort the functional groups in your model.4 To add and edit functional groups to an Ecopath model, choose the ''Edit groups...'' option on the [wiki:EwEugEcopathMenu Ecopath menu] on the ''Menu bar''.

To exit without implementing any changes, click the ''Cancel'' button. 7 7 8 After adding model groups on the ''Edit groups'' form, you can proceed to the ''Input data'' forms to enter parameters for your groups (i.e., [ [Basic input.htm|Basic input]], [[Diet composition.htm|Diet composition]], [[Detritus fate.htm|Detritus fate]] and [[Other production.htm|Other production]] forms, accessible in the ''Navigator window'' under the ''Input data'' node).8 After adding model groups on the ''Edit groups'' form, you can proceed to the ''Input data'' forms to enter parameters for your groups (i.e., [wiki:EwEugBasicInput Basic input], [wiki:EwEugDietComposition Diet composition], [wiki:EwEugDetritusFate Detritus fate] and [wiki:EwEugOtherProduction Other production] forms, accessible in the ''Navigator window'' under the ''Input data'' node). 9 9 10 10 '''Add/insert groups''' … … 22 22 You must define whether a functional group is a primary producer, consumer or detritus by checking the appropriate box. 23 23 24 * Primary producers (producers) obtain all of their energy from photosynthesis. By definition, their [ [Trophic level decomposition.htm|trophic level]] is 1.24 * Primary producers (producers) obtain all of their energy from photosynthesis. By definition, their [wiki:EwEugTrophicLevelDecomposition trophic level] is 1. 25 25 26 26 27 27 * Consumers obtain their energy by consuming other organisms. They have trophic level > 1. 28 * Detritus groups are dead. Note that you must enter at least one detritus group and you can have as many detritus groups as you like. Note also that detritus groups must be placed after all living groups (i.e., they must have a higher group number than the last living group). You must also specify where the surplus detritus (left over after feeding by detritivores) will go using the [ [Detritus fate.htm|Detritus fate]] form.28 * Detritus groups are dead.
