    This helps illustrate by, in a way, dividing the words by Herero or auto and chemo or photo, and then picking one or the other from the diagram of carbon and energy. This really helped me understand it visually, thank you so much!

    What does energy source mean for animals ?Where is it needed? I didn't get it.
    I understood the carbon source so we are heterotrophs .

    • @BiologyProfessor
      @BiologyProfessor  7 років тому +1

      All organisms need some kind of energy to grow, reproduce, maintain homeostasis, etc. Phototrophs (like algae or plants) get their energy directly from sunlight. Animals get their energy (and their carbon) from food. In other words, animals eat food that contains carbon and that also contains energy in the bonds that carbon forms with other carbon atoms or with atoms of other elements. In breaking down those bonds during cellular respiration, energy is released and stored in molecules of ATP until the cell needs it. But remember that ultimately, even the energy contained in the food we eat comes from the sun, because the food we eat is composed either of plants or of animals that eat plants. I hope this helps!

  • @kingo717
    @kingo717 7 років тому +1

    What are inorganic chemicals and organic sources?

    • @BiologyProfessor
      @BiologyProfessor  7 років тому +1

      The main determinant is whether a compound contains carbon or not. Organic compounds are those that contain carbon, like carbohydrates and proteins, which can also contain other atoms, like nitrogen, sulfur, phosphorous, etc. Inorganic chemicals are those that do not contain carbon, but contain other atoms instead, like nitrogen, sulfur, and more. Some organisms use organic compounds to obtain energy, others use inorganic compounds.

    Can chemotrophs or chemoautotrophs make their own food? Do you need to obtain inorganic and organic sources from other organisms or can you make the yourselves? How do you identify if an organism can me its own food or not? I don't understand. Thank you.

    • @BiologyProfessor
      @BiologyProfessor  7 років тому +2

      When we say "make their own food" we typically are referring to photosynthesis or chemosynthesis, where organisms use one of these processes (using light or chemicals for energy) to "fix" atmospheric carbon dioxide or other compounds into sugars (the food). Chemoautotrophs do this (chemosynthesis) to "make their own food" (the sugars). Chemoheterotrophs do not; they have to ingest materials for food instead. As for the question about how to identify an organism as being one of these types, it depends on what you mean. A scientist who is studying a new organism will look at where it gets its nutrients and energy and look closely at its cellular metabolism to make the determination. On the other hand, if you mean how does a STUDENT know, the answer is that a student will need to learn about different types of organisms (plants vs animals vs fungi vs cyanobacteria vs archaebacteria for example) and memorize which categories these organisms fit into.

    • @BiologyProfessor
      @BiologyProfessor  8 років тому

      Organotrophs: Organic compounds are used as electron donor.
      Lithotrophs: Inorganic compounds are used as electron donor.
      You can read a bit more about it here: en.wikipedia.org/wiki/Primary_nutritional_groups#Primary_sources_of_reducing_equivalents
      Hope this helps!

  • @JudithSamp
    @JudithSamp 7 років тому +1

    For further explanation, I got confused, because our Prof uses the word litho instead ot hetero. Is that possible? So ist chemolithotroph the same as chemoheterotroph?

    • @BiologyProfessor
      @BiologyProfessor  7 років тому +2

      No, they are not the same. Heterotrophs cannot fix their own carbon from carbon dioxide, they must get it somewhere else. Chemoheterotrophs are organisms that obtain energy by the oxidation of chemicals in their environments (rather than using light energy). Chemoheterotrophs can be chemolithoheterotrophs, utilizing inorganic energy sources (such as sulfur) or chemoorganoheterotrophs, utilizing organic energy sources such as carbohydrates, lipids, and proteins. This is summarized from Wikipedia, hope it helps!

    • @BiologyProfessor

      You are correct. The molecules used by chemotrophs can be organic (chemoorganotrophs) or inorganic (chemolithotrophs). This distinction is made less commonly in my experience, but thank you for pointing it out!

    • @BiologyProfessor
      @BiologyProfessor  3 роки тому

      No, not from CO2 like a photoautotroph. Photoheterotrophs use light for energy, but need to take in "food" (organic compounds from the environment, like carbs, fatty acids, and alcohols) to satisfy their carbon requirements.

    • @BiologyProfessor
      @BiologyProfessor  3 роки тому

      We use oxygen (inorganic) as our final electron acceptor, making aerobic respiration possible. But really, for heterotrophs, I should have said the energy comes from chemicals (not inorganic chemicals) - because yes, we get energy from organic compounds by using the power of oxygen.
