URGENT: A fungus kills 75% of the plant life in tropical areas such as Florida, Mexico, Central America, and the Bahamas. These areas include plants that do not go into a dormancy, like in New England, and a significant percentage of global rain forests. Would might be the global result as it relates to: photosynthesis rate, amount of atmospheric carbon dioxide, and ecosystem balance.

Yes, it affects photosynthesis rate, amount of atmospheric carbon dioxide, and ecosystem balance.

Explanation:

Plants have the ability to clean the environment by absorbing carbondioxide gas during the process of photosynthesis. These plants are the important part of ecosystem and their removal causes imbalance of ecosystem. These plants provide habitat and food etc. If plants were killed because of fungal attack so decrease occurs in rate of photosynthesis, concentration of carbondioxide gas in the atmosphere and disturbed the balance of ecosystem.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
