Answer 2

The seeds of some plants are dispersed by animals.Plants such as burdock have hooks to which the seed is attached. These hooks easily get caught in the fur of mammals as they pass by the plant. At some point the seed will fall, often a considerable distance from the parent. If conditions are right the seed will germinate and grow into a new plant.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 them.The small hard seed is hidden inside the fruit and passes through the gut of the animal as it cannot 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.Nuts such as Hazelnuts and acorns are also distributed by animals and birds. Jays are conspicuous in the Autumn as they collect acorns to  tide them over the lean Winter. They may be responsible for the collection of several thousand acorns per bird. Not all of the acorns will be eaten, leaving some to germinate and produce new trees.Squirrels are famous for collecting nuts, not all of which will be eaten. Some will be forgotten and left to germinate later.
