In this section, I talk about communities. It’s a part of the chapter entitled Communities and Biomes from the textbook Biology: The Dynamics of Life. Join me as I explore the relationships between the populations of a community. I then go into the concept of tolerance and show how Limiting factors can restrict the size of a population. The topic of Primary and Secondary succession is also dealt with, and I show how those processes result in the formation of a climax community. Enjoy!
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.
Watch Video →Section 1.2 in the book Biology: The Dynamics of Life deals with the Methods of Biology. In this section, I talk about the Scientific method, which shows the steps that are used to answer questions scientifically. Of course, when talking about the scientific Method, you have to include a discussion of Controlled experiments.
