Explanation:

Both statements are incorrect.

• Fungi can be single celled or very complex multicellular organisms.
• They are found in just about any habitat but most live on the land, mainly in soil or on plant material rather than in sea or freshwater.
• A group called the decomposers grow in the soil or on dead plant matter where they play an important role in the cycling of carbon and other elements.
• Some are parasites of plants causing diseases such as mildews, rusts, scabs or canker.
• A very small number of fungi cause diseases in animals. In humans these include skin diseases such as athletes’ foot, ringworm and thrush.

Hence option 4th is correct.
