True or False: Species protection acts tend to be more expensive and widespread than ecosystem protection acts
False
True or False: Natural Selection is a short process carried out over only a few years and generally in one generation*
False
If a sunflower has 10,000 J of energy, how much energy would a hawk consume? Assume the food chain is Sunflower > Grasshopper > Mouse > Hawk. Assume standard trophic efficiency.
10 J
What are the reasons that not all of the energy an organism possesses gets passed on when it is consumed by the next organism? (Choose the best answer)
The energy an organism consumes is also passed off as feces, used in cellular respiration and other functions
_______________ is the ability of an organism to tolerate a chemical or disease-causing agent.
Resistence
Pollutants becoming more concentrated in organisms higher in the food chain is called:
Bioaccumulation
What is the selective breeding of organisms, by humans, for specific desirable characteristics?
Artificial Selection
In the Water Cycle, what are the two terms that describe how the water falls to the earth and then how it is (generally) sent back up?
Evaporation (Up), Precipitation (Down)
What is the trophic efficiency level that we use as a standard in this class?
10%
The number of species in a given area is called:
Species Diversity
Walker really enjoys eating squirrel. So much so that he has a whole cookbook of squirrel recipes. The only issue with this is what he has moved to a new country and there aren't any squirrels here. He solves this by bringing in his own herd! What is the potential main issue that could come from introducing a new species to his new environment?
The squirrels might not have natural predators in this environment, becoming invasive
You have a warm, desolate environment. Water is hard to come by. There are two types of Caleb Buffalo in this environment. One has thicker fur and the other has the ability to drink and store water at an elevated rate. Which Caleb Buffalo will survive and reproduce easier here?
The Water Caleb Buffalo
In the Carbon Cycle, how is CO2 broken down?
Photosynthesis
What are the reasons that not all of the energy an organism possesses gets passed on when it is consumed by the next organism? (Choose the best answer)
The energy an organism consumes is also passed off as feces, used in cellular respiration and other functions
The number of habitats in an ecosystem is called:
Ecological Diversity
What are the three levels we talked about in regards to how close a species is to non-existence? Pick the one that is in correct order (from left to right, least in danger to most)
Threatened, Endangered, Extinct
We gave the example of the honeycreepers adaptation in our lecture notes. It adapted at the same time as a flower, benefiting both. What is this an example of?
Coevolution
Why do some biogeochemical cycles go global while others tend to stay localized?
Gaseous cycles tend to be able to spread on a global level, where less mobile cycles like calcium tend to not be able to move far
What is a Biogeochemical cycle?
Nutrient cycles in ecosystems involving biotic and abiotic components
What do we call a species that is vitally important to an ecosystem?
Keystone Species
What is the current era of extinction we are in called?*
The Holocene Era
Which of these would be an example of selective breeding?
Dogs
What is a Biogeochemical cycle?
Nutrient cycles in ecosystems involving biotic and abiotic components
Which of the following would be an example of Natural Selection?
A salamander developing natural camouflage to hide from predators
Which of these are not a benefit of biodiversity we listed in our slides?
Solves overpopulation
