Substrand: "4.1 Organisms in their environment"
(25 periods)
Different types of living things live at different places of the environment called its habitat. The habitat of any organism (living thing) will contain essential things for its life. These may be other living things for food and mates or non living things like the soil, water or environmental conditions. There is a continuous interaction and dependence among the living things themselves and between the livings with non living things in any environment. For a long time, human beings had put considerable impacts on other organisms and the environment.
