2. a butterfly visits a flower to drink nectar.
3. moss is growing on the roots of a tree.
4. a worm buries in the soil.

6. a squirrel drinks from a puddle of water.

a. the butterfly, moss, and hawk only
b. the spider and worm only
c. the moss and butterfly only
d. all of the organisms

Explanation:

• Butterfly and flower: The butterfly (biotic) interacts with the flower (biotic) as it drinks nectar.
• Moss and tree: The moss (biotic) interacts with the tree (biotic) as it grows on the tree roots.
• Spider and fence: The fence is abiotic (non - living), so this is a biotic - abiotic interaction.
• Worm and soil: The soil is abiotic (non - living), so this is a biotic - abiotic interaction.
• Hawk and tree: The tree is abiotic in terms of the hawk just circling above (no direct biotic - biotic interaction like consumption or symbiosis shown here).
• Squirrel and water: The water is abiotic (non - living), so this is a biotic - abiotic interaction.

Answer:

C. The moss and butterfly only
