a. mutualism
b. commensalism
c. amensalism
d. neutralism
e. parasitism

Explanation:

1. The holly leaf - miner eats holly leaves. Producers are plants, and primary consumers eat producers. So the holly leaf - miner is a first - level or primary consumer.
2. Batesian mimicry is when a harmless species mimics a harmful one. The scarlet king snake (harmless) mimics the coral snake (venomous), so this is batesian mimicry.
3. Mullerian mimicry is when two or more unpalatable or dangerous species resemble each other. Both the viceroy and monarch butterflies are distasteful to predators and look similar, so this is mullerian mimicry.
4. Commensalism is a symbiotic relationship where one organism benefits and the other is neither helped nor harmed. The barnacle benefits by getting a place to live on the whale, and the whale is unaffected, so this is commensalism.

Answer:

1. A. first - level or primary consumer
2. D. batesian mimicry
3. A. mullerian mimicry
