Virtual Lab Major Takeaways Different ecosystems have different

Virtual Lab Major Takeaways • Different ecosystems have different organisms living there • All ecosystems have abiotic and biotic factors – Abiotic= nonliving • Ex. Temperature, rainfall – Biotic = living • Ex. Plants, animals, bacteria

Virtual Lab Major Takeaways • Flow of energy through an ecosystem – When one organism consumes (eats) another, energy is transferred from the organism that is eaten to the organism that eats it – Most of the energy an organism takes in is released as heat • Only about 10% of the energy available at one level of a food chain transfers to the next • Think back to our energy pyramid notes!

Virtual Lab Major Takeaways • Identify positions on a food chain or food web – Producer – Primary consumer – Secondary consumer – Tertiary (third) consumer – Decomposer • Why don’t food chains have 10 links (ex. 10 th order consumers)? – Think back to the previous slide about the energy available at each level of the food chain/web

What you ultimately need to know • Identify/define the following terms: – Abiotic and biotic factors – Producer, consumer, decomposer, herbivore, carnivore, omnivore – Primary, secondary, tertiary consumer • Be able to draw/analyze the following: – Food chain/food web – Energy pyramid
