| Further, both biotope and biocenosis were respectively considered as abiotic and biotic parts of an ecosystem. |
| The biocenosis is extremely rich as regards both quality and quantity, containing several hundred species. |
| The sediment fauna is the same as that of the biocenosis of well sorted fine sands. |
| The fairly deep bowls of the platforms constitute enclaves for a flora and a fauna that belong to the biocenosis of photophilous algae. |
| The 'hardware', design, and technology must provide optimum conditions for the microbial biocenosis that carries out the AD process. |
| Indeed, it appears to be difficult to fully describe a facies or an association without having first set them within their biocenosis. |
