Q. No.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
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:
| 1. | primary metabolites | 2. | secondary metabolites |
| 3. | cofactors | 4. | pollens |
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:
| 1. | competitive exclusion | 2. | predation |
| 3. | exploitative competition | 4. | interference competition |
Monarch butterflies are toxic and unpalatable to predators because they:
| 1. | incorporate the toxic chemicals from the milkweed they eat |
| 2. | produce their own secondary compounds |
| 3. | break down the toxic chemicals from the milkweed they eat |
| 4. | live with symbionts that secret toxins |
Cryptically colored animals are most likely:
| 1. | Batesian mimics | 2. | is palatable to predators |
| 3. | aquatic | 4. | top predators |
Number of species in a community is an indicator of its:
| 1. | spatial heterogeneity | 2. | ecosystem productivity |
| 3. | species diversity | 4. | species richness |
Identify the correct statement:
| 1. | Eutrophic lakes contain fewer nutrients than oligotrophic lakes. |
| 2. | Xerarch succession is a primary succession that occurs in water bodies. |
| 3. | Most ecologists believe that most communities achieve stable, unchanging climax vegetation. |
| 4. | A mature ecosystem has greater species richness, greater biomass, and less net productivity than a younger stage of succession. |
