Question

In Southeast Asia, there's an old saying: 'There is only one tiger to a hill.' In terms of energy flow in ecosystems, explain why big predatory animals such as tigers and sharks are relatively rare.

Accepted Answer

Hey everyone. Let's take a look at this question together. Which of the following statement is incorrect. So let's take a look at the statements listed below to try to figure out which of the following is incorrect. So taking a look at the options we have listed. We know that we're dealing with energy change in an ecosystem. So let's recall what we've learned about how energy changes within an ecosystem. So we know that at the bottom we have our producers and then we know that we have our primary consumers and then it goes to our secondary consumers. And lastly we have our tertiary consumers. And so now that we've written this down, let's take a look at our statements to see if it is correct or incorrect. So answer choice A. Says D. Composers make up the majority of the food chains population. And we know that those D. Composers are the organisms that consume dead and decaying matter. And that would be your fun guy or your bacteria and several other microorganisms. And we know that those have the greatest population in the food chain. So answer choice A. Is a correct statement. Answer choice B. Says the lowest number of organisms would be found at the highest Trophic level so the highest trophic level is our tertiary consumers, which we know that the tertiary consumers consume the secondaries which consume the first which consume the producers. And in this pattern the number of organisms decreases. And so the number of organisms decreases as you go up the chain. So answer choice B is another true statement. Looking at answer choice C. We see the energy flows in a cyclic pattern, which would mean that from the producers, the energy that gets transferred to the consumers from primary to secondary to tertiary would come all the way back down, which we know. That is not how it works and that the energy only flows upwards in a single direction. So that means that answer choice C. Is not a correct statement. So that would be our answer, since we know that the flow of energy in an ecosystem is in a single direction. So answer choice D. Is also a true statement and answer choice C is the only statement listed. That is incorrect. I hope you found this video to be helpful. Thank you and goodbye.
