Answer 1

1. Spanish Moss comes under the category of commensalism because it gets benefit from the tree (southern live oak) but do not cause any harm to oak. Spanish moss does not have any roots, so it wraps itself in the branches of trees and collects water from a special scale like structure  present on its leaves. It is considered as a +/0 relationship but here since we have only 3 options +,-,0 then it will be 0.

2. It is also a commensalism realtionship with (+) relation. Because here moss is not getting benefited from other organisms but those organism are being protected by Spanish moss.

3. It is a symbiotic relationship because here both Rhizobia bacteria as well as plant get benefited from each other. It is a positive relatonship.

4. These microbes (Downy mildew) are obligate parasites of plants. Downy mildew belongs to peronosporaceae. Hence, these type of relationships are Negative (-) relationships.
