Question

1. a type of bacteria lives in the roots of plants. the bacteria helps the plants obtain nutrients. the roots are a moist home, which helps the bacteria grow and reproduce.
2. the fungus known as \chicken of the woods\ grows on trees. the fungus breaks down the tree and gets its nutrients that way. the tree decays, gets weak, and becomes very vulnerable to extreme weather.

Explanation:

1. In the first case, both the bacteria and the plant benefit. The bacteria helps the plant get nutrients and the plant provides a living - space for the bacteria. This is mutualism.
2. In the second case, the fungus benefits by getting nutrients from the tree, while the tree is harmed as it decays and becomes vulnerable. This is parasitism.

Answer:

1. Organism 1: Bacteria; Organism 2: Plant; Symbiotic Relationship: Mutualism
2. Organism 1: Fungus; Organism 2: Tree; Symbiotic Relationship: Parasitism
