Detritus production rate

Gives a named vector with the rates at which different components of the ecosystem produce detritus:

1. biomass not assimilated by predators ("feces"),

2. decomposing carrion ("carrion"),

3. the pelagic zone ("external").

Usage

getDetritusProduction(
  params,
  n = params@initial_n,
  n_other = params@initial_n_other,
  rates = getRates(params)
)

Arguments

params

MizerParams

n

A matrix of current species abundances (species x size)

n_other

Other dynamic components. Only n_other$carrion is used.

rates

A list of rates as returned by getRates()

Value

A vector with named entries "external", "feces" and "carrion", giving the rates at which carrion biomass is produced by these sources in grams per year.

Details

The function returns a vector with the individual contributions. These can be summed with sum() to get the total production rate.
