Plants have evolved various strategies to secure animals into eating their fruit and spreading their seeds without relying solely on sugar.
Step-by-step explanation:
Plants have evolved various ways to secure animals into eating their fruit and spreading their seeds without relying solely on sugar content. One strategy is to produce fleshy fruits that are attractive to animals. When animals consume these fruits, the seeds pass through their digestive tract unharmed and are excreted, allowing for seed dispersal. Another method is the development of specialized fruits, like burrs, that stick to animals' fur and are transported to new locations. Additionally, some plants have co-evolved with specific pollinators that are attracted to their nectar, ensuring that pollen is transferred only between flowers of the same species.
