and the arthropod predator Caridina multidentata. A stable model ecosystem hydrosphere can be constructed using the appropriate combination of species.
10.1.2 Culture Vessel and Culture Conditions
An example of an ecosystem model using aquatic animals and plants is shown in
Fig. 10.2. The experimental apparatus should contain glass beads (1 L) for planting
submerged plants and 4 L of lake water in a 5 L beaker. The apparatus should be
installed in a thermostatic chamber at 20
C that blocks light from the outside. An
irradiance of 5000 lux and fluorescent lamps that can be adjusted to create day and
night (L/D) cycles should be used.
10.2 Chemical Substance Addition Experiment
10.2.1 LAS
An experiment was performed for the purpose of constructing a standard by planning
the construction of the model ecosystem (scaled-up model ecosystem) hydrosphere
using larger aquatic organisms in addition to the microcosm N-system, evaluating
