Whale barnacles attach typically to baleen whales without harming them. This relationship is called as:

1.	vitalism	2.	mutualism
3.	parasitism	4.	commensalism

A parasitism that does not involve feeding on the body of the host is:

The adaptation that a prey species avoid being detected by a predator would be:
1. Mullerian mimicry
2. Batesian mimicry
3. aposematic coloration
4. cryptic coloration

The appearance of an animal that warns predators it is toxic, distasteful or dangerous is called as:
1. Batesian mimicry
2. Mullerian mimicry
3. aposematic coloration
4. cryptic coloration

The chemical defence produced by plants against herbivory are:

All the following are symbiotic relations except:
1. monarch butterflies and viceroy butterflies
2. lichens
3. mycorrhizae
4. tapeworms and humans

To avoid herbivory milkweeds secret latex containing:
1. cardiac glycosides
2. stipules
3. mustard oils
4. strychnine

The two species physically interfere with one another by aggressively attempting to exclude one another from particular habitats in:

Monarch butterflies are toxic and unpalatable to predators because they:

Cryptically colored animals are most likely:
