The logistic population growth is expressed by the equation:
1.
2.
3.
4.
Which one of the following is most appropriately defined:
1. | Amensalism is a relationship in which one species is benefited whereas the other is unaffected |
2. | Predator is an organism that catches and kills other organism for food. |
3. | Parasite is an organism which always lives inside the body of another organism and may kill it. |
4. | Host is an organism which provides food to another organism. |
Cuscuta is an example of:
1. Brood parasitism
2. Predation
3. Endoparasitism
4. Ectoparasitism
Annual migration does not occur in the case of:
1. Salmons
2. Siberian crane
3. Salamander
4. Arctic tern
Niche overlap indicates:
1. | active cooperation between two species |
2. | two different parasites on the same host |
3. | sharing of one or more resources between the two species |
4. | mutualism between two species |
The formula for exponential population growth is:
1. dt/dN= rN
2. dN/rN= dt
3. rN/dN= dt
4. dN/dt= rN
Praying mantis is a good example of:
1. Mullerian mimicry
2. Warning colouration
3. Social insects
4. Camouflage
A high density of elephant population in an area can result in:
1. mutualism
2. Intraspecific competition
3. Interspecific completion
4. Predation on one another
