<h1><strong>HABITAT</strong></h1> CONTENT <ol> <li>Meaning of Habitat</li> <li>Types of Habitats</li> </ol>   <h2><strong>Meaning of Habitat</strong></h2> The place where an organism normally lives is called its habitat. Specifically, it means the home where an organism (plant or animal) inhabits. The biologists who study habitats are called <strong>ecologists</strong>. Ecology is the study of organisms in relation to their environment. There are many kinds of habitats. The school compound is a habitat, a pond is a habitat and the tropical rain forest of Africa is a habitat. <br> <h2><strong>Types of Habitats</strong></h2> There are basically three types of habitat. They are aquatic habitat, terrestrial habitat and arboreal habitat. 1.<strong> Aquatic (Water) Habitat</strong>: This habitat refers to water environment. Organisms found in this habitat are called aquatic organisms. There are three types of aquatic habitat:

Factors are the things or conditions that influence their livelihood. These factors are called <strong>biotic</strong> and <strong>abiotic </strong>factors. Biotic factors are the living factors of the habitat such as the living things found in that habitat while the abiotic factors are the non-living factors in the habitat such as oxygen, temperature, dissolved salt, water, sun light, etc. The biotic factors are classified as producers, consumers and decomposers.

Photosynthesis and respiration drive the movement of oxygen and carbon dioxides to become available all the times.   <h2><strong>The Water Cycle</strong></h2> We use water every day, where does water comes from, water is found almost everywhere in different forms. Water cycle is the continuous movement of water, from land, rivers and oceans to the atmosphere as vapour and from atmosphere back to land and rivers or oceans as rain.

They belong to a special group of animals called mammals. As mammals, they possess the following characteristics: <ol> <li>They have high level of intelligence</li> <li>They give birth to young ones alive (viviparous)</li> <li>They possess hair or fur on every part of their body or certain part of the body</li> <li>They breast-feed their young ones with milk from the mammary glands e.g cow, sheep, cat, man</li> <li>they have four chambered hearts</li> <li>they are warm blooded animals</li> </ol> <br> <h2><strong>Man as a Primate</strong></h2> Mammals can be subdivided into many groups, one of the sub-groups is primates. Human beings belong to a sub-group of mammals called primates. Primate is a member of an order of mammals with a large brain and complex hands and feet. All primates are mammals but not all mammals are primates. Among the primates are man, gorilla, chimpanzee and monkeys. <img class="size-full wp-image-19634 aligncenter" src="https://classhall.com/wp-content/uploads/2018/06/man-as-a-primate.jpg" alt="Man as a primate" width="520" height="371" /> They have the following characteristics as primates:
