Energy Flow in an Ecosystem and Symbiotic Relationship

What is the difference between a food chain and food web? Food webs only follow just one path as animals find food A food chain shows the many different paths that energy flows through many plants and animals. A food chain only follows just one path as animals find food A food web shows the many different paths that energy flows through many plants and animals. A food chain consists of many food webs. A food chain only follows just one path as animals find food. Match the parts of the food chain. Producer Grass Primary Consumer Grasshopper Secondary Consumer Mouse Tertiary Consumer Snake Quaternary Consumer Hawk Pond Food Chain Energy Flow Click on each organism from the pond food chain and label it with the amount of energy it has. The rule is, is that it only passes on 10%. So divide by 10. The plant will start at 100,000 units of energy do the math to figure out the rest. 100,000 10,000 1,000 100 10 1 Answer the following questions using the pyramid below. Which trophic level has the most energy? 1st trophic level (producers) 2nd trophic level (primary consumers) 3rd trophic level (secondary consumers) all levels have the same amount of energy What happens to the amount of energy available to organisms when moving from trophic level 1 to trophic level 2? the energy increases by 90% the energy decreases by 10% the energy decreases by 90% the energy increases by 10% Sort it out Put the following scenarios to their correct heading. Mutualism A bee wants nectar from a flower, the flower attaches pollen to the bee to reproduce. Clownfish live in an anemone, the anemone is cleaned by the clownfish. Commensalism Tree frogs use plants as protection, the plant gets nothing in return. The remora fish follows behind a shark to eat it's leftovers. The shark gets nothing in return. Parasitism Mosquitos bite humans for blood, human are left with a mosquito bite Fungus grows on a human foot, the human's foot burns and itches. Competition Orca whales hunting seals, sharks, and penguins. Dolphins chasing and eating fish. Predation A lion attacking an elephant A snake attacking a chicken. Amensalism A penicillin killing bacteria
