Using what you know about the transfer of energy among trophic levels
Using what you know about the transfer of energy among trophic levels, explain why there are so few top predators compared to the organisms in the other trophic groups (e.g. producers, primary consumers, secondary consumers) within a given ecosystem?
Homework Answers
Energy is passed from one trophic levels to other in increasing order of trophic level from producuc-herbivorous-1st carnivores and so on.Only 10%energy is passed on .So at top carnivores level,a very less energy remain for their need .this small energy can be used by small population of top carnivores.If population will be larger ,no one could get enough energy .

1) If you examined predator-prey relationships within an ecosystem and noticed that the removal of predators also resulted in the die-off of herbivores, what would you suspect occurred? a) Removal of predators would directly lower the number of herbivores. b) The lack of predators could mean that too much primary production occurred. c) Herbivores from another region may have entered the ecosystem and consumed the primary producers, causing death of the original herbivores species. d) Overeating by herbivores could have...

1: What do trophic relationships illustrate about an ecosystem? 2: About how much of the sun's energy is converted, captured, or fixed by primary producers? 3: Net Primary Production is always lower than Gross Primary Production. What happens to the difference? 4: Does energy flow through an ecosystem or is it recycled? Why? 5: How does climate determine the distribution of ecosystems?

What is a food chain? What is a food web? What are trophic levels? (see class notes and Campbell pp. 1221-1223) What is the role of primary producers in food chains? Why is the biomass of consumers in a community determined by the net primary production (NPP) of the autotrophs in a community. What abiotic environmental factors affect the net primary production in a community? Gives examples of some communities with high NPP and some with low NPP. Open Ocean...

NPP = GPP – R
Net primary production =
______________
= GPP – energy used for cellular respiration
Gross primary production = ________________ production of
primary producers
Respiration = ______________________
Thus NPP is the amount of energy available to primary
consumers = primary production
Explain the different ways in which primary production is
influenced in terrestrial and aquatic ecosystems
Primary production: terrestrial

Which statement about organisms' "niche" is false? The niche summarizes environmental factors influencing growth, survival, and reproduction of a species The "fundamental" niche refers to physical, but not biological, aspects of the environment Interactions such as competition and parasitism may restrict the size of an organism's niche In the laboratory, two species with identical niches are especially easy to maintain in a mixed culture Which of the following is NOT a population characteristic favored by K-selection? low intrinsic rate of...
