Answer:
Yes, it affects photosynthesis rate, amount of atmospheric carbon dioxide, and ecosystem balance.
Step-by-step 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.
