In the natural world it is often hard to survive alone, so one species often relies on another in order to thrive. This is known as mutualism.
Mutualism is a relationship between different species, where both parties benefit.
For example, the honeysuckle requires help with pollination.
By emitting a special scent, it attracts the hummingbird hawk moth, which is rewarded with nectar from the honeysuckle's flower.
While drinking nectar, the moth makes contact with stamens, which brush it with pollen.
Once exhausted of pollen, the stamens shrivel. Now as the moth drinks nectar, it brushes pollen from another flower onto the stigma.
So the moth enjoys a meal and the honeysuckle is pollinated.
Other plants use mutualism to help with seed dispersal.
In southern Nepal, trewia trees drop their fruit on the forest floor, where little light can reach them. However, they need light to grow.
Enter the Indian rhinoceros. During the hottest part of the day, these rhinos feed in the shady forest, eating trewia fruit as they go.
When the temperature cools they move to open grassland where, in their dung, they deposit the indigestible trewia seeds on the ground.
This means the seed is dispersed to a sunny spot along with a supply of fertiliser. And in return, the rhino has had a meal.
Mutualism is also handy when it comes to defence.
In Africa, the acacia tree defends itself with spines, but despite this, some animals are determined to eat it.
So the acacia employs ants as bodyguards, providing them with homes and food.
In return, when a herbivore shakes the branches of the tree, the ants hurry toward it, attacking its tongue and lips, thus defending their home and protecting the acacia.
Mutualistic relationships between plants and animals aid reproduction and survival, proving it pays to work together in the wild.
