Which of the following is true of trophic relationships in an ecosystem? All energy in the food chain is ultimately transferred to top level carnivores Most of the useable energy transferred between trophic levels is maintained--very little is lost The trophic pyramid predicts that top level carnivores should have the least amount of biomass in an ecosystem Net productivity is typically a measure of over-all photosynthesis in an ecosystem

Which of the following is true about energy flow in ecosystems on Earth? 99% of energy that reaches the earth is used to drive the process of photosynthesis Only about 10% of energy is moved from one trophic level to the next, while the remaining is lost as heat A very small amount of solar radiation that reaches the earth is scattered or reflected The Law of Conservation of Energy states that energy cannot be destroyed, but it can be created in plants
Net primary productivity refers to the rate of energy storage as organic matter by autotrophs after respiration is deducted the total rate of photosynthesis, or energy assimilated, by autotrophs the amount of accumulated organic matter found in an area at a given time the production of new tissues and offspring by heterotrophs
In the trophic structure, autotrophs are living organisms that: Are at the top of the chain, referred to as tertiary producers. Photosynthetic organisms that produce their own energy Organisms that receive their energy by consuming producers such as plants Help to decompose the remains of dead organisms
In an ocean ecosystem, the biomass of an algal community is approximately 3000 kilograms. It can support a food chain up to 4 levels. Considering an efficiency at an average of 10% in passing on energy from one trophic level to the next level, how much biomass of the fourth trophic level can be maintained.
For every megajoule of used by the phytoplankton in the michigan. How many joules of energy are used in building cell tissue in the lake trout?How many in humans? Use the food chain pathPhytoplankton > zooplankton > alawite > lake trout > humansGiven that only 10% of energy consumed is converted biomas.
ctional What proportion of energy stored at one trophic level ends up being LOST as it moves to the next trophic level? O 10% O 25% O 50% O 75% O 90%
support or refute the following statements based on what you learned about energy flow, biogeochemical cycling, decomposition, trophic levels, and keystone species. You may add a diagram or illustration to support your answer. Shark fin soup can cause the collapse of coral reef ecosystem
Availability of energy is less for entities at higher trophic levels. Why?
Availability of energy is less for entities at higher trophic levels.Why?
The trophic levels found in this ecosystem are decomposers, producers, consumers, secondary consumers, and top predators. Which one of these converts light energy into chemical energy?
An organism exists for long periods by using only CO2 and H2O. herbivore. carnivore. decomposer. autotroph. heterotroph.
Why are terrestrial autotrophs responsible more global productivity than marine producers? higher local biomass per unit productivity ocean temperature limit cellular physiology currents stress out the plankton terrestrial CO2 is more accessible for uptake all of the above
