In a forest ecosystem, a food chain might look like this: If the green plants are destroyed in a forest fire, which short-term effect will this have on the organisms in this food chain?
Most mountain lions will leave the area.
Rabbits will obtain their energy from coyotes
There will be fewer rabbits for coyotes to eat.
There will be more coyotes for mountain lions to eat.
If wolves prey on deer for food, what will most likely happen to the deer population if wolves are removed from an area where deer live?
The population of deer will increase.
The population of deer will decrease
The population of deer will remain the same.
The population of deer will become extinct.
The following is a food chain observed in a large wilderness park. A swarm of insects consumes 70% of the vegetation in the park. As a result, which of the following will MOST likely occur?
The prey will decrease in numbers.
The predator will increase in numbers.
The prey will be unaffected.
The predator will be unaffected.
What happens to a population and to competition when there is a reduction of living space?
The population expands and competition intensifies.
Competition strengthens while the population contracts.

It has approximately 20% of the energy level below it.
A diagram of an Everglades food web is shown. Energy is transferred from organism to organism in a food web. Some organisms, such as the leopard frog, are secondary consumers. Others, such as herbivorous carp, may be primary consumers or secondary consumers, depending on which organism they consume. Which of the following populations in this food chain provides the greatest amount of energy as a food source?
raccoon
herbivorous carp
utricularia
american alligator
Which diagram BEST illustrates the flow of energy in an ecosystem?
In a food pyramid, which best explains why the number of organisms decreases from one trophic level to the next?
Consumers at the lower level require more energy than the top-level consumers.
Consumers at the top level require more energy than the lower-level consumers.
The consumers are feeding on larger organisms that have less energy.
The consumers are feeding on smaller organisms that have less energy.
This energy pyramid models the flow of energy between organisms in a Florida ecosystem. Which statement describes how energy flows in the pyramid?
Energy is lost between each level.
Energy is consumed only at Level 1.
The most energy available is at Level 3.
Equal amounts of energy are transferred between levels.
Where do plants get most of the energy they need to live and grow?
toilet
soil
air
sunlight
The food chain shows the flow of energy through an ecosystem. What is the role of decomposers in the system?
They recycle oxygen back into the ecosystem.
They recycle energy from dead organisms back to the ecosystem.
They absorb energy from sunlight to pass on to other organisms.
They obtain and use the energy that remains in living organisms.
