Matter (a) through the ecosystem.
Energy used for body processes are given off as heat and is not passed to other organisms in a usable form best explains what?
Some energy at each level is destroyed and cannot be passed to other organisms.
Less energy is generated by the organisms in higher trophic levels,
The organisms at each level are less efficient at using energy than those in the previous levels.
Energy used for body processes are given off as heat and is not passed to other organisms in a usable form.
Which correctly compare the amount of available energy in different trophic levels in an ecosystem?
Select all correct responses
First-level consumers have less available energy than second-level consumers
Producers have more available energy than third-level consumers
Third-level consumers have more available energy than first-level consumers
Second-level consumers have less available energy than first-level consumers
The producers are the trophic levels with the _____ amount of available energy.
least
same
greatest
equal
Choose the response that is NOT an important role of carbon for organisms in an ecosystem?
It makes up compounds in soils that are important for plant growth and health
It is used to make up sugars like glucose

This global food web shows how parts of a meadow ecosystem interact with parts of a marsh ecosystem.
Which of these is a food chain that is part of the global food web?
meadow grass → rabbit → fox → hawk
marsh grass → snail → small fish → hawk
marsh grass → grasshopper → mouse → fox
meadow grass → grasshopper → praying mantis → small fish
What happens during an energy transformation in a living thing?
Energy is created.
Energy is destroyed.
Energy is permanently stored.
Energy changes from one form to another.
What is the difference between a food web and an energy pyramid?
There is no difference; food webs and energy pyramids show the same types of relationships between organisms.
Food webs show all the feeding relationships between organisms, while energy pyramids show how energy moves from producer to consumer.
Food webs show an animal at the top of the energy pyramid, while energy pyramids show only how producers get their energy.
Energy pyramids show how energy flows between organisms, while food webs show only the different organisms in an ecosystem.
