Q. No.A population interaction that is detrimental to both species would be:
| 1. | Mutualism | 2. | Competition |
| 3. | Predation | 4. | Amensalism |
Consider the given statements regarding competition amongst organisms:
| I: | Only related species can compete for the same resource |
| II: | Competition occurs only when the resources are limiting |
The correct statement/s is/are:
| 1. | I alone | 2. | II alone |
| 3. | Both I and II | 4. | Neither I nor II |
A process in which the fitness of one species is significantly lower in the presence of another species, is termed as :
| 1. | Predation | 2. | Parasitism |
| 3. | Competition | 4. | Amensalism |
Abingdon tortoise in Galapagos islands became extinct within a decade after goats were introduced on the island due to:
1. Habitat fragmentation
2. Better browsing efficiency of goats
3. Predator of goat attacking tortoise
4. Virus of goats parasitizing tortoise
“Competitive Exclusion Principle” may be true if:
| 1. | The competing species are equally capable |
| 2. | Resource partitioning occurs |
| 3. | There is only intraspecific competition |
| 4. | Resources are limiting |
One mechanism that promotes co-existence rather than exclusion amongst competing species is:
| 1. | Periodic migration | 2. | Hibernation and aestivation |
| 3. | Resource partitioning | 4. | Reproductive isolation |
All the following relations are examples of commensalism except:
| 1. | Sea anemone and clown fish |
| 2. | Cattle egret and grazing cattle |
| 3. | Barnacles growing on the back of whale |
| 4. | Cuscuta growing on hedge plants |
