Select the correct option from following:

  1. (a)-(iv), (b)-(ii), (c)-(i), (d)-(iii)
  2. (a)-(iii), (b)-(ii), (c)-(iv), (d)-(i)
  3.  (a)-(ii), (b)-(i), (c)-(iii), (d)-(iv)
  4.  (a)-(i), (b)-(iii), (c)-(iv), (d)-(ii)

Solution

Mycorrhiza: This is a mutualistic relationship between fungi and roots of higher plants. Fungi absorb essential nutrients from the soil while the plants, in turn, provide energy-yielding carbohydrates to the fungi.

Competition in the broadest sense refers to the interaction of two organisms striving for the same resource. Sheep and cattle both are herbivores and fight for the same resource when present together. It is an example of an interspecific competition.

In predation, only one species (predator) benefits and the interaction is detrimental to the other species (prey). Herbivores are predators and plants are prey.

Epiphytes (orchids) growing on other plants like mango (host) gets benefit in the form of shelter but the host neither drives any apparent benefit nor does it get harmed. Such an interaction is called commensalism.
