Unit 7 Reflection

In this unit we learned about ecology.We learned about food chains and food webs. Autotrophs provide energy for other organisms in an ecosystem. Heterotrophs are organisms that get their energy by eating other living things. Food chains and food webs model the flow of energy in an ecosystem. A food chain shows how each organisms get its energy. Tropic levels are levels in a food chain based on what something eats. From the bottom ts primary producers, primary consumers, secondary consumers, tertiary consumers, and the lastly, Quaternary consumer. Biomass is the method of measuring energy. Biodiversity is threatened due to habitat loss, introduced species, overexploitation, and change in climate. We also watched a movie called bag it. We learned how much plastic we use and why we should stop using so much plastic. We also took a questionnaire and I learned that I am passive. I should try to be more assertive.
