d. Pollinators rely on the flowers for food and have to pollinate to survive
Explanation:
Insect pollination is more successful as compared to wind pollination which is completely a chance event. Insect pollinated plants have evolved several strategies to attract pollinators.
The co-evolution of insect-pollinated plants further ensures the mutualism between them. Pollinators derive their food from the flowers they visit in the form of nectar.
Due to their food requirements, insects visit the flowers and in turn pollinate them. If insects do not visit the flowers, they will face the food scarcity. To ensure food availability, insects visit the flowers and pollinate them.
