| 21. | Many of the barriers to top-down trophic cascades also promote stability.
|
| 22. | These include primary productivity ( production of trophic interactions.
|
| 23. | One aspect of trophic levels is called tritrophic interaction.
|
| 24. | Properly managed multi-trophic aquaculture accelerates growth without detrimental side-effects.
|
| 25. | Currently, ecological networks that integrate non-trophic interactions are being built.
|
| 26. | They are, in turn, central prey items for higher trophic levels.
|
| 27. | Humans are also at the top of the trophic pyramid, particularly newborns.
|
| 28. | Example : Assume 500 units of energy are produced by trophic level 1.
|
| 29. | Large predator fish with higher trophic levels have been depleted in wild fisheries.
|
| 30. | This augmented community matrix provided a probabilistic trophic network.
