The diets of several types of prairie animals are described in the table. Which of the following prairie food chains is in the correct order?
Eagles --> prairie dogs --> coyotes
Wildflowers --> badgers --> grasshoppers
Sparrows --> seeds --> insects
Grasses --> prairie dogs --> badgers
In a food chain, energy does NOT flow directly from -
producer to decomposer
producer to consumer
consumer to decomposer
consumer to producer
Analyze the food webs. Which food web has the greatest biodiversity?
They have equal biodiversity.
Food Web X
Food Web Y
There is not enough information to determine biodiversity.
Surtsey is an island located south of Iceland. The island was formed by a volcanic eruption and first appeared in 1963. The table below contains descriptions of changes in the population and diversity of species on Surtsey. Which of these lists the descriptions in the correct order of ecological succession on Surtsey?
I, II, IV, III
III, I, II, IV
IV, III, I, II
II, IV, I, III
Which table shows the correct role of each organism in the food chain?
Scientists observe two different habitats in North America. In the event of a natural disaster, which habitat most likely survives and has the ability to rebuild?
Habitat 2 survives and rebuilds because there are less species that escape the natural disaster.
Habitat 1 survives and rebuilds because there is less biodiversity.
Habitat 1 survives and rebuilds because there is more biodiversity.
Habitat 2 survives and rebuilds because there is less biodiversity.
The rocky material left behind by a retreating glacier forms what is called a moraine. When primary succession occurs on a moraine, which organisms will help create the soil by breaking down bare rock?
Insects
Lichens
Grasses
Deciduous Trees
The energy pyramid below shows the energy made available by producers. Based on the energy flow between trophic levels in an energy pyramid, how much energy would be expected to be found at the secondary consumer level in this pyramid?
0.01%
0.1%
1%
10%
What is the best explanation for what the arrows in a food chain represent?
The arrows demonstrate in which direction the animal or plant is moving.
The arrows demonstrate the order in which a plant or animal consumes food.
The arrows demonstrate how much each animal eats.
The arrows demonstrate the flow of energy through the food chain.
Based on the model, which consumer receives the least amount of energy from the producers?
Primary consumers
Secondary consumers
Tertiary consumers
Quaternary consumers
