The Transfer of Energy in Ecosystems

Which of the following statements about energy transfer in a food chain is true?
1. Only some of the light and heat from the sun is absorbed by producers
2. The energy transfer in a food chain proceeds through a series of producers
3. In food chains, energy moves both upward and downward through one biotic element to another
4. About 90% of the energy taken in by a food source is available to the organism that consumes it
Which one of the following types of consumers could be a herbivore?
1. Primary consumer
2. Secondary consumer
3. Carnivore
4. Producer
Why are there fewer organisms at the top of an energy pyramid?
1. Very little of the sun's energy is available to the top level
2. These organisms have the fewest food sources
3. Organisms at the top level live longer than those on lower levels
4. Organisms at the top have complicated family structures to support
Which one of the following statements about food chains is false?
1. The energy transfer in an ecosystem always ends with the Sun and producers
2. Food chains show how energy is transferred in an ecosystem
3. At each step in a food chain, less energy is available to the next consumer
4. Food chains show how energy and matter flow from one biotic element to another
Which part of a food chain absorbs the Sun's light and heat?
1. Producers
2. Consumers
3. Herbivores
4. Omnivores
What is the correct order of how energy travels through an ecosystem?
1. Sun>producer>herbivore>carnivore
2. Carnivore>herbivore>producer>Sun
3. Sun>omnivore>carnivore>herbivore
4. Sun>producer>omnivore>herbivore
Which statement about the energy available to the next level as you move up a food chain is incorrect?
1. Most of the Sun's energy is available to the next level in a food chain
2. At each level of a food chain much energy is lost as heat
3. The stored energy of an organism is available to the organism that consumes it
4. At each level in a food chain, energy is used up in the processes of living and growing
Which choice is not one of the ways in which energy is used at each level in a food chain?
1. Food consumption
2. Heat
3. Stored
4. Living processes
Which choice correctly completes the following statement? As the food chain gets longer,
1. less energy is transferred from one organism to the next.
2. fewer producers are available to create energy.
3. more omnivores are involved in the transfer of energy.
4. more energy is available to each type of consumer.
Which one of the following organisms is most likely to be at the top of a food pyramid?
1. Owl
2. Rabbit
