Question

Write short notes on (a) Predation (b) Mimicry (c) Mutualism (d) Antibiosis.

Answer 1

All of these are biological interactions. These interactions connect one organism with another one.

Complete step by step answer:
Predation
1.It is preying on one animal on the other.
2.Predation is mainly done by carnivores and omnivores.
3.The nutrition and energy for the predator is obtained from the prey.
4.Predation is necessary to maintain an ecological balance.
5.It maintains the number of the particular animal.
6.An imbalance in it can cause disruption of the food chain and food web.
Mimicry
1.It is the close external resemblance of an animal or a plant with another animal or plant or even inanimate objects.
2.It may evolve in individuals within a genus or within a species.
3.Mainly the evolution of mimicry is to protect itself from the predators.
4.In mimicry they pretend to be something or someone else thus it escapes from the predator.
Mutualism
1.It is an ecological interaction between two or more species, where each of the involved organisms is benefited.
2.Here as the name suggests the benefits are mutual.
3.The organisms involved may belong to different species, it can also be different organisms too.
4.The organism involved does not harm one another.
Antibiosis
1.It is an interaction between two or more organisms where one organism is detrimental to the other.
2.Here one organism harms the other organism which is involved.
3.It either causes a disease or can even lead to the death of the other organism.
4.The best example for this is a host-pathogen interaction, where the pathogen harms the host which gives it nutrition and shelter.

Note:
1.Predation is preying.
2.Do not confuse mimicry with camouflage.
3. Mimicry in biology is that the body is evolved to resemble something or someone else so as to escape from the predators.
4. Whereas camouflage is a defence mechanism or a tactic used by the prey when they sense a danger from the predator. So that they can escape the predator.
5.Antibiosis is one organism acting against the other one.
