can you mention any one mechanism through which plants attract them?
Through bright colors and attractive smells.
Frugivore
Many animal-dispersed fruits advertise their palatability to animals with bright colors and attractive smells (mimetic fruits). Fruit pulp is generally rich in water and carbohydrates and low in protein and lipids.
what is an orangutan? It is a great ape native to Indonesia and Malaysia. where from the name originates? It comes from the Malay words "orang", meaning "man", and "hutan", meaning "forest". what do they feed on? Fruit, primarily. are fossils of this primate found?

Frugivores how are these animals significant to the environment? They cause seed dispersal in many ecosystems.

Frugivore [SEP] Plant adaptations to attract dispersers
There are a number of fruit characteristics that seem to be adaptive characteristics to attract frugivores. Many animal-dispersed fruits advertise their palatability to animals with bright colors and attractive smells (mimetic fruits). Fruit pulp is generally rich in water and carbohydrates and low in protein and lipids. However, the exact nutritional composition of fruits varies widely. The seeds of animal-dispersed fruits are often adapted to survive digestion by frugivores. For example, seeds can become more permeable to water after passage through an animal's gut. This leads to higher germination rates. Some mistletoe seeds even germinate inside the disperser's intestine.
