These slides go into some of the basic principles of ecology and how organisms interact with each other and the environment. I also go into nutrition and energy flow.
Watch Video →All organisms (living things) require energy in order to do ANYTHING. Where does all this energy come from? Well, go ahead and watch those videos and you will find out. In the lecture, I talk about the source of energy, producers vs. consumers, the different types of heterotrophs and a number of other details.
Watch Video →Organisms do not exist in isolation. In fact, they depend on other organisms AND also nonliving things. These interactions are necessary for life to exist and we notice that, in nature, a change in one population affects other populations in an ecosystem. This is something that can lead to interesting consequences.
Watch Video →This is section 1.3 in the book Biology: The Dynamics of Life. I talk about quantitative vs. qualitative research, how science is influenced by society, the difference between pure science and applied science and then I finish off with the definition of technology, when it comes to science.
