A tight one-to-one relationship between a fig species and its pollinator wasp species is an example of:
The text highlights this as an example of 'co-evolution of the mutualists, that is, the evolutions of the flower and its pollinator species are tightly linked with one another.'
Which of the following interactions is characterized by both species benefiting, often involving co-evolution?
The passage describes mutualism as conferring benefits on both interacting species, and specifically mentions that 'plant-animal interactions often involve co-evolution of the mutualists'.
Plants offering rewards like pollen and nectar to animals for pollination is a strategy to:
The text states, 'Animals obviously have to be paid ‘fees’ for the services that plants expect from them. Plants offer rewards or fees in the form of pollen and nectar for pollinators and juicy and nutritious fruits for seed dispersers.'
What is the role of the plant in the mycorrhizal association?
The NCERT states, 'while the plant in turn provides the fungi with energy-yielding carbohydrates' in mycorrhizal associations.
The Mediterranean orchid Ophrys demonstrates a unique mutualistic interaction to ensure pollination using:
The NCERT text mentions, 'The Mediterranean orchid Ophrys employs ‘sexual deceit’ to get pollination done by a species of bee. One petal of its flower bears an uncanny resemblance to the female of the bee...'
Which of the following is NOT an example of mutualism?
Lichens, mycorrhizae, and plant-pollinator interactions are explicitly stated as examples of mutualism. The cattle egret and grazing cattle represent commensalism, where one benefits and the other is neither harmed nor benefited.
In the context of mutualism in plant-animal relationships, why do plants offer rewards?
The text states: 'Animals obviously have to be paid ‘fees’ for the services that plants expect from them. Plants offer rewards or fees in the form of pollen and nectar for pollinators and juicy and nutritious fruits for seed dispersers.'
Which term best describes the reciprocal evolutionary changes between intimately associated species, such as a fig tree and its pollinator wasp?
The passage explicitly states, 'plant-animal interactions often involve co-evolution of the mutualists, that is, the evolutions of the flower and its pollinator species are tightly linked with one another' with the fig-wasp relationship as an example.
A 'cheater' in a plant-pollinator mutualistic system is an animal that:
The text mentions safeguarding against 'cheaters', 'for example, animals that try to steal nectar without aiding in pollination.'
The interaction between two different species where both receive benefits, denoted by a '+' sign for each species, is known as:
Mutualism is defined by 'both species benefit', which in the provided notation means both species have a '+' interaction, hence (+, +).
