Lily reads the following paragraph about garter snakes:
"Garter snakes may live in a variety of places, including meadows, forests, and along the stores of a pond. They hunt and eat small rodents and amphibians, and they will eat birds' eggs. They provide food for larger predators, including hawks and raccoons."
By citing information from this paragraph, Lily can most usefully answer which of these questions?
How does the garter snake depend on microhabitats?
What is the carrying capacity of a meadow for garter snakes?
What is the tolerance of the garter snake to changes in its environment?
What is the niche of the garter snake?
Walleyes and northern pike are both species of fish that live in freshwater lakes. Many lakes maintain large, healthy populations of both of these fish species year after year. Which statement about walleyes and northern pike is MOST USEFUL in explaining how they are able to live together in the same habitat?
The two species adapted to eat different types of food.
The two species have different ranges of tolerance to oxygen content in water.
The two species adapt to eat the same types of food.
The two species have different ranges of tolerance to temperature.
Scientists have classified the sea otter as a keystone species in communities along the Pacific coast of North America. This classification depends on which property of the sea otters?
Sea otters have the highest population in the community.
Sea otters act to maintain a wide variety of other populations in the community.
Sea otters are the largest, most massive members of the community.
Sea otters provide food for all of the predators in the community.
Termites are able to digest wood because of microbes that live in their gut. The relationship between a termite and the microbes inside it is an example of what type of symbiosis?
parasitism
mutualism
commensalism
predator-prey relationship
Thomas is describing an example of secondary succession. Which of the following events is most useful for him to include?
Lichens begin growing on rocks that formed from a volcanic eruption.
Many fishes die in a pond when oxygen levels decrease.
The populations of wolves and rabbits change in a cyclical pattern.
Small plants and animals return to the land after a forest fire.
ex. barnacle on whale
In (a) , one species harms another species to benefit themselves. For example, a flea bites a dog to get (b) . This leaves the (c) with itchy bite marks.
Barbara is studying the process of ecological succession in a temperate forest ecosystem. Her goal is to construct an explanation based on evidence. Observations of which the following locations is most likely to provide useful evidence for Barbara to cite?
A healthy, undisturbed temperate forest ecosystem.
A healthy, temperate forest ecosystem a few years after a wildfire.
A farmer's field that had been cleared from a temperate forest.
A temperate forest that is changing due to invasive vines.
After a volcanic eruption, volcanic rock is present (but no soil). Which of the following states the most likely order of succession that would be seen?
Lichens → Shrubs → Grasses → Trees
Lichens → tree → shrubs→Grasses
Grasses → Lichens → Shrubs → Trees
Lichens → Grasses → Shrubs → Trees
True or false: hurricanes, tornadoes, floods, and fires are examples of secondary succession
True
False
Scientists have observed that all cheetahs have very similar body structures, markings, and other physical traits. These observations provide evidence for which conclusion?
Cheetahs have low genetic diversity.
Cheetahs have low species diversity
Cheetahs have high genetic diversity.
Cheetahs are minimally affected by biodiversity.
Carla claims that a strain of rose bushes is resilient to temperatures as low as 5 degrees C. Which statement about rose bushes of this strain can be inferred from Carla's claim?
They grow better at 5 degrees C than at higher temperatures.
They grow better at higher temperatures, but can survive at 5 degrees C.
They grow as well at 5 degrees C as at higher temperatures.
They can survive at 5 degrees C without inputs such as water and sunlight.
Which of the following describes a benefit of biodiversity to an ecosystem?
Decreases the energy flow through the ecosystem.
Increases the maximum number of trophic levels.
Increases the maximum biomass of the ecosystem.
Allows the ecosystem to withstand environmental changes.
Food production, purifying water, storing carbon, and regulating pests are all examples of what?
ecosystem services
ecosystem resilience
abiotic factors in ecosystems
biodiversity
