What is climax vegetation how does it work?

Climax vegetation are those plants which form the stable, long term ecosystem in a given environment. For instance in Europe after the Ice sheets melted, the ground was barren of plants. Then slowly mosses, grasses and small plants colonised the area, building up a soil humus, then more shrubby plants were able to grow and the ecosystem got richer. Finally deciduous forest trees were able to establish and the region became forested. These plants then formed the long term stable vegetation cover and are therefore called the climax vegetation. If you go further north deciduous forest gives way to evergreen pine forest as in this environment pine trees are the climax vegetation.


What does a black stallion eat?

A black stallion is a horse, and like any other horse, its food needs will depend on its size and work level. Horses eat grass, and in the wild this is the only food they would readily eat. However, in winter, horses will eat hay, bran and chaff. If there is snow on the ground or little grass (or if the grass is dead in summer) they will need supplementary feeding on quality hay. Horses that are being worked will need concentrates to keep their energy up, such as oats, corn or commercial horse feed. The more time a horse spends under saddle (or pulling a plough, or on the lunge line, or working in any other way) the more concentrates it will need to stay in condition. Retired horses, foals and horses that are not under work often do not need concentrates.A stallion is a male horse. Horses eat grasses like oats, wheat, or barley. They graze in open grass lands. Horses do not eat other animals, they are called herbivores.
