c. Mention two harmful effects of fungi?
d. Explain the role of microorganisms in cleaning the environment?
Answer (2)
Fungi can cause health issues and spoil food, while microorganisms assist in cleaning the environment through bioremediation and nutrient recycling. Their activities maintain ecosystem balance and contribute to sustainability. Understanding the roles of fungi and microorganisms is essential in biology.

Fungi and microorganisms play significant roles in our world, both beneficial and harmful. Let's explore these aspects:
c. Mention two harmful effects of fungi:
Diseases in Humans and Animals: Some fungi are pathogenic and can cause diseases in humans and animals. For example, Candida infections can cause conditions like athlete's foot or thrush. These fungal infections can lead to discomfort and, if untreated, may result in more severe health issues.
Crop Diseases: Fungi can have detrimental impacts on agriculture. Certain fungal species infect crops and cause diseases, leading to reduced yields and agricultural loss. For instance, rusts and smuts are fungi that can damage cereal crops like wheat and corn, affecting food supply and farmer revenues.
d. Explain the role of microorganisms in cleaning the environment:
Microorganisms play a crucial role in environmental cleaning through processes such as decomposition and bioremediation.
Decomposition: Microbes like bacteria and fungi are key decomposers in nature. They break down organic matter from dead plants and animals, recycling nutrients back into the ecosystem. This process helps maintain soil fertility, balancing ecosystems and providing energy for other organisms.
Bioremediation: Certain microorganisms can degrade pollutants, making them invaluable for environmental cleanup. For example, some bacteria and fungi can break down oil spills or detoxify heavy metals in contaminated soil or water. This natural process helps in cleaning up polluted environments and restoring ecological balance.
By understanding these roles, we can appreciate how microorganisms contribute to the health and sustainability of our environment.
