| Which of the following processes will be most adversely affected if micro-organisms are removed from a forest ecosystem? |
Solar energy fixation and nutrient cycling. Decomposition of organic matter and photosynthesis . Nitrogen fixation and decomposition of organic matter. Carbon assimilation and nitrogen fixation. |
| Nitrogen fixation and decomposition of organic matter. |
| If microbes are removed from a forest ecosystem, nitrogen-fixation and decomposition of organic matter will be high affected. There are many nitrogen-fixing microbes involved in biological nitrogen-fixation. Bacteria and fungi secrete enzymes to degrade organic matter into simpler inorganic substances. |
