Question

One species is harmed whereas the other is unaffected. Such type of interaction is called
(a) Commensalism
(b) Amensalism
(c) Parasitism
(d) Predation

Answer 1

Hint:A biological phenomenon by which an organism produces one or more biological phenomena by which an organism produces one or more biochemicals that influence the expansion, survival, and reproduction of another organism.

Complete answer:
Amensalism is that the sort of relationship that exists where one species is inhibited or completely obliterated and one is unaffected. In allelopathy, thanks to biochemicals produced by one organism, the opposite organism might not be ready to survive.
Example- Black walnut trees store allelopathic properties within their buds, nut hulls and root which is liable for its toxicity called juglone, remains within the soil around the tree.
Other forms of population interactions are:
- Commensalism:
- This is the association between two organisms in which one benefits and therefore the other derives neither benefits nor harm.
- Species involved live together without getting into any quite physiological exchange.
Example- An epiphyte may be a plant. Growing on another plant gives the epiphyte better access to sunlight and moisture like orchid species.
- Parasitism:
- In this one organism, the parasite derives nourishment from another organism, its host which is harmed within the process.
- Parasites survive or in their hosts often for long periods.
- Parasitism features a negative effect on hosts but doesn't usually kill hosts.
Example- Numerous microorganisms living on the skin of the human for prey on only.
- Predation:
- Predation is when the organism of 1 species as a predator consumes part or all of another species prey.
- These are often herbivorous like plants and eaters or carnivores like meat and eaters.
So, the right answer is, ‘amensalism.’

Note:
- Species interaction refers to the direct or indirect interrelationship between different organisms, which can be in between plants and plants, plants and animals and animals and animals and also interaction with microorganisms like bacteria, fungi, etc in which the interaction can harm or benefit the other organism.
- Species interaction is of the following types Competition- interspecific and intraspecific, Predation – carnivory, and herbivory, Parasitism, Commensalism, Mutualism, and Amensalism.
