taking in carbon dioxide
Which type of organism makes its own food?
consumer

Which kind of diagram shows how much energy passes along as one organism consumes another?
decomposition
energy pyramid
food chain
food web
Which of these shows the flow of energy in a food chain?
decomposers > consumers > plants > producers
sun > consumers > producers > decomposers
producers > predators > decomposers > consumers
sun > producers > consumers > decomposers
In this food chain, what would be a possible energy source for the bacteria?
all the animals
all the organisms
only the hawk
only the predators
In a forest food chain, what is the connection between the sun and a tree?
The sun helps chlorophyll turn oxygen into carbon dioxide.
The tree shades animals from the sun and gives them nutrients.
The sun heats up the ground so the tree's roots can take in water.
The tree uses the sun's energy to make food through photosynthesis.
Alex notices a small spot of fungus growing on an orange in the back of his refrigerator. He doesn't eat it, but looks at it again a week later. Which of these is he most likely to observe?
The fungus has gone away.
The fungus has not changed.
The fungus has grown larger.
The fungus has changed color.
Which of these happens during the time a fallen log is decomposing?
The fallen log slowly begins to die.
The fallen log continues to produce food.
The materials in the log combine into new, complex parts.
The materials in the log are broken into smaller, simpler parts.
Why are bacteria shown at the end of the food chain?
They are producers, and make food from sunlight.
The are consumers, and feed off of the dead hawk.
They are decomposers, and break down the dead hawk.
They are consumers, and the smallest organisms in this chain.
Hawks eat snakes. Snakes eat toads. Toads eat grasshoppers. Grasshoppers eat plants. Which of the statements below about this food chain is correct?
A toad is an herbivore.
A grasshopper is a producer.
A hawk is a second-level consumer.
A snake is a first-level consumer.
If the number of fish dropped suddenly, which of the following is a likely short-term effect in the food web?

as both a consumer and prey
as both a producer and consumer
as both consumer and scavenger

Mold grew faster on the dry bun.
Mold grew the same on both buns.
Mold did not grow inside sealed bags.
Mold grew faster on the moistened bun.
