which statement about ecological pyramids is false?

They were either beacons for alien spacecraft or pharonic burial tombs

Anthropogenic (human caused) climate change involves:

all the above and also some gasses absorb and randomly reemit in infrared.

Not a potential characteristic of an invasive species:

lives only in the ecosystem in which it evolved

A hawk that eats frogs can be described by all the following:

tertiary consumer, heterotroph, predator

Possible negative impacts of current global climate change include all but one:

A sudden snap into a new ice age.

High levels of biodiversity indicate a healthy ecosystem because:

ecosystems are more resiliant to disruptions

One of these contains an answer that is not a characteristic of all life:

Internal homeostasis and evolves and made EXCLUSIVELY of carbon.

Energy, Matter
Matter, Information
Information, Matter
Matter, Energy
2
which statement about ecological pyramids is false?
They were either beacons for alien spacecraft or pharonic burial tombs
they roughly correspond to the 10% rule
Models energy, biomass and species numbers across trophic levels.
A similar but inverse exponential effect explains biomaginification.
3
Which best describes the biome in Lake Stevens?
coniferous forest
Temperate forest
Taiga
Tundra
4
Anthropogenic (human caused) climate change involves:
positive feedback mechanisms like the albedo effect.
a sharp increase in the concentration of carbon dioxide in the atmosphere
A sharp increase of the concentration of methane gas in the atmosphere
all the above and also some gasses absorb and randomly reemit in infrared.
5
Not a potential characteristic of an invasive species:
Negatively affects other species and disupts ecosystem balance.
lives only in the ecosystem in which it evolved
may outcompete native species as a predator.
may have chemical or bodily defenses that protect it from predators
6
A form of symbiosis in which both species benefit:
commensalism
anarcho syndicalist communism
parasitism
mutualism
7
That first one was tough! In the scientific method, which comes first?
perform an experiment
collect the data
form a hypthesis
Publish your results
8
A hawk that eats frogs can be described by all the following:
primary consumer, herbivore, predator.
Your Uncle Sally and Aunt Bob.
tertiary consumer, heterotroph, predator
secondary consumer, autotroph, decomposer
9
Possible negative impacts of current global climate change include all but one:
A sudden snap into a new ice age.
sea level rise seriously disrupting many coastal cities
Increased extreme weather
Reduction of arable land (places that can support productive farms)
10
High levels of biodiversity indicate a healthy ecosystem because:
biodiversity measures how big the population of a species is.
ecosystems are more resiliant to disruptions
it demonstrates that animals have been evolving for longer in this location
3 rings for elves, 7 for dwarvish lords, 9 for men and 1 to rule them all..
11
One of these contains an answer that is not a characteristic of all life:
made of cells and reproduces
Internal homeostasis and evolves and made EXCLUSIVELY of carbon.
Takes/eliminates materials and responds to the environment
grows and uses a universal genetic code.
12
Which one is not a density dependent limiting factor?
viral infections
parasitism
competition
extreme drought
13
These two classes of biomolecules are used by cells to make the following structures: Cell Membranes and Enzymes...
lipids and protiens
nucleic acids and lipids
carbohydrates and lipids
proteins and carbohydrates
14
A limiting factor can turn a ____________ growth pattern into a ________________ pattern.
logistic, exponential
exponential, demographic
exponential, logistic
carrying capacity, exponential
