This document discusses several topics including trees, buildings, animals, and natural phenomena. It defines trees as having woody stems that grow upright and distinguishes them from bushes. It describes the main functions of a tree's trunk and branches. It defines animals as multicellular organisms in the kingdom Animalia that are heterotrophs. It associates buildings with human civilization and the development of sciences like architecture and engineering to support building construction. It provides examples of natural phenomena like weather events, volcanic eruptions, and decay as non-artificial events not created by humans.

5. Is a major part of the tree trunk and became the main liaison between the roots, as collectors of water and minerals, and the tree canopy (canopy), as the central processing of input energy (sugar production and reproduction). Branch is also the stem, but smaller than the function expanding leaves room for growth so it gets more sunlight and also suppress the growth of competitors in the vicinity. Trunk covered with skin that protects the shaft from damage.In everyday language, understanding the tree a bit wider, which in botanical called "pseudo-tree

6. Animal or animals are a group of organisms that are classified in the kingdom Animalia or metazoans, is one of many living things on earth. Other designations are the fauna and wildlife (or animals only).

7. Animals in the sense of modern systematics includes only multicellular groups (multicellular) and organized in different functions (network), so the group is also called Histozoa. All animals heterotrophs, meaning not create its own energy, but must pick up from the surrounding environment.

8. The building is usually connoted with houses, buildings or any facilities, infrastructure or infrastructure in culture or human life in building a civilization as well as bridge design and construction, roads, telecommunications facilities. Generally, a civilization of a nation can be seen from the techniques of building and facilities created or left by humans in the course of history.

9. Because the buildings associated with the advancement of human civilization, then on his way, people need a science or engineering related to building or supporting the making of a building. The development of science is inseparable from it as well as architecture, civil engineering related to buildings. Even the use of trigonometry in mathematics is also associated with a building allegedly used during the ancient Egyptians in building the Pyramids. Even today, in the form of a high-rise building construction is considered to be characteristic of the progress of human civilization.

10. Natural phenomena are non-artificial event in the view of physics, and then not created by humans, although it can affect humans (eg bacteria, aging, natural disasters). Common examples of natural phenomena, including volcanic eruptions, weather, and decay.Aurora is one of the natural phenomenon

11. Mostly harmless natural phenomenon like rain. Natural phenomena such as volcanic eruptions, tsunamis and tornadoes are considered hazardous and can cause kematian.Fenomena is uncommon in the life of the world and can occur with unexpected and seemingly impossible in view of the human.
