Introduction: Species interact with each other in the ecosystem for their survival. These interactions can be understood by the food chains and food webs where species depend on each other for certain nutritive benefits. However, these interactions can be beneficial for one and harmful to others, or sometimes beneficial for both.
Answer to Problem 1TY
Correct answer: In an interaction where species is benefitted, and the other species is not harmed is known as commensalism. Hence, the correct answer is option d.
Explanation of Solution
Reason for correct answer:
Commensalism is the type of species interaction in which one is benefited, and the other species remain unharmed or unaffected. This type of interaction is depicted as ‘+/0’, where ‘+’ sign refers to as benefits, and ‘0’ refers to as unaffected or experiences no loss.
Option d is given as, “Commensalism”.
The interaction in which one is benefitted and the other species is not harmed is called commensalism. Hence, option d is correct.
Reasons for incorrect answers:
Option a. is given as, “Mutualism”.
It is a symbiotic relationship in which both species are mutually benefitted. This type of interaction is depicted as ‘+/+’. Hence, option a. is incorrect.
Option b. is given as, “Amensalism”.
In this type of interaction, one is harmed, and another is not affected. It is depicted as ‘-/0’. This interaction is generally observed in predation. Hence, option b is incorrect.
Option c. is given as, “Parasitism”.
In this type of interaction,
Option e. is given as, “Mimicry”.
Mimicry is not an interaction; it is an adaption. In this type of adaptation, the species adapt or acquire some features of other ones in order to protect themselves from predators. Hence, option e is incorrect.
Hence, options a, b, c, and e are incorrect.
Species interact with each other to survive, and it is natural. These interactions can be understood by the food chains and food webs where species interact to get food.
