|Hooks are not the only way by which plant seeds are distributed. Many plants
produce fruits which animals such as birds and mammals eat.
In the autumn blackberries
are a common sight in British woodlands and hedgerows. The berries
are eaten by birds such as blackbirds and pigeons. Mice, deer and even foxes eat also eat
The small hard seed is hidden inside the fruit and passes through the gut of the animal as it can not
be digested. The seeds are therefore expelled in the droppings of the animal. Some seeds
dispersed in this way cannot germinate unless they have passed through the digestive
system of an animal.
