Hello everybody! Here you have the most important information you need to know for the first exam of Natural Science. You are going to do it very well! PARTS OF THE CELL : UNICELLULAR AND MULTICELLULAR ORGANISMS: Organisms that have only one cell are called unicellular organisms. Organisms that are made up of many cells are called multicellular organisms. VITAL FUNCTIONS: All living things perform three vital functions : 1.  Nutrition:  All living things obtain nutrients from their environment to live, grow and develop. They transform them into energy . For example: Plants produce their own food through photosynthesis . Animals feed on other living things . Decomposers feed on dead plants and animals. 2.

The defending team instead positions themselves to defend the ball against the Tchouk! How to play Tchoukball? To play tchoukball, two official tchoukball rebound surfaces and a handball ball are needed. The game is played on a handball court (20X40 meters) between two teams of nine players or on a basketball court between teams of six or seven players. The rebound surfaces (which can be used by both teams) are placed at each end of the court, and each one is within a semi-circle line, with a three meters radius, which defines the forbidden zone. The team that has possession of the ball has a three-pass limit before being forced to shoot the ball at t...

1. ELEMENTS OF ECOSYSTEMS An ecosystem includes all the living things and non-living things in a specific area and the interaction that occurs between them.   LIVING THINGS : plants (flora) animals (fauna) other organisms, such as fungi and microorganisms. Organisms in the same area form groups. Those that belong to the same species are called a population . Populations interact with each other and form a community .   NON-LIVING THINGS (Physical environment) soil (rocks and minerals) air water sunlight temperature climate      A habitat is the place where a plant or animal normally grows or lives.     2. THE EARTH'S TERRESTRIAL ECOSYSTEMS TUNDRA:    Tundra is the coldest ecosystem on Earth and it is also very dry . It is located in the land areas near the North Pole. Its main characteristic is the absence of trees. Flora : lichens, mosses and some grasses. Fauna : reindeers, caribou, a...
