Study the graph below, which shows food availability in a given area over 25 years.Created for Albert. All rights reserved.If the food source shown in the graph is shared between various species in an ecosystem, you might predict all of the following to occur over time, EXCEPT:Elimination ToolSelect one answerAIncreased competition between the organisms that share the food source.BDecreased growth rates of the organisms that share the food source.CIncreased reproduction rates of the organisms that share the food source.DDecreased survival rates of the organisms that share the food source.Skip For No

A model of a food web is provided in the diagram below.If organism IV is eliminated from the population, what long-term effect could this possibly have on organism V?ResponsesOrganism V would be preyed upon by organism III.Organism V would be preyed upon by organism III.Organism V would not be affected.Organism V would not be affected.Organism V could become eliminated from the ecosystem.Organism V could become eliminated from the ecosystem.Organism V could become overpopulated.

Explain how competition between organisms affects the availability of resources in an area.

The diagram below shows the food webs of two simple marine ecosystems, A and B.Explain which ecosystem is more resilient by describing what would happen to each if the wrasse went extinct.

Suppose that scientific research reported that the cod population was reduced in the ecosystem represented by the food web.What result would be most likely over time?Group of answer choicesThe penguin population may decrease.The leopard seal population may decrease.The photosynthetic plankton population may decrease.The krill and zooplankton populations may decrease.

13) In lines given above, it is stated that “Food web A represents a more diverse ecosystem with, as a result, many more alternative feeding pathways.” Look at FOOD WEB A. Only two animals in this food web have three direct(immediate) food sources. Which two animals are they?*1 pointNative Cat and Parasitic WaspNative Cat and Butcher BirdParasitic Wasp and SpiderNative Cat and HoneyeaterOption 514) . Food webs A and B are in different locations. Imagine if Leaf Hoppers died out in both locations. Which one of these is the best prediction and explanation for the effect this would have on the food webs?*1 pointThe effect would be greater in food web A because the Parasitic Wasp has only one food source in web A.The effect would be greater in food web A because the Parasitic Wasp has several food sources in web A.The effect would be greater in food web B because the Parasitic Wasp has only one food source in web BThe effect would be greater in food web B because the Parasitic Wasp has several food sources in web B.15) Which of these statements is NOT true?*1 pointAn animal can be located at more than one type of trophic level in a food webThe position of an organism in a food chain is due to its food preferencesUnlike food chains, food webs represent multidirectional transfer of energyFood web is made due to species that occur in more than one food chain16)  Organisms of a higher trophic level which feed on several types of organisms belonging to a number of lower trophic levels constitute*1 pointFood webFood chainEcological pyramidEcosystem
