Reflection on topics taught in term 3

In term 3, we learnt reflection of light, ecology, and the carbon cycle. I must say that the topics taught in this term are relatively easy as most of us got good grades in the term 3 tests. For reflection of light, the angle of incidence is wqual to the angle of reflection and the distance of the object from the plane mirror is same as the distance of the image form the mirror. The image is virtual as no actual light rays are captured form the screen and is upright and laterall inverted. There is the diffused reflection and the specular reflection, the type of reflection formed depends on the direction of the reflected ray, the type of surface of the reflective object and the direction of the light source. For ecology, we learnt about the different types of organisms in a food web, such as autotrophs, heterotrophs and decomposers, and the different types of relatonships of organisms, such as commensalism and exploitative relationships. There are abiotic factors that affect the ecosystem such as humidity and wind speeds. For ecology we learnt the various ways of how carbon is recycled, for example, when forests are burnt in slash and burn cultivation, large amounts of carbon dioxide is released form the destroyed plant material.
