A climax community

Logistic growth
Consumers are organisms that obtain their energy and nutrients by eating and digesting other organisms
Tertiary consumers are animals that eat the animals that eat the animals that eat plants
Producers are organisms that extract their energy from nonliving components of their environment
Decomposers are organisms that obtain energy and nutrients from the remains and wastes of other organisms
All of the above are correct

Population
Predators will always competitively exclude their prey
Dominant species can always outcompete recessive species
K-selected species will always outcompete r-selected species
Two species may occupy the same niche in a given community by sharing its resources
No two species competing for the same resources can stably coexhist

That different places have different thicknesses to the atomosphere
That the earth is shaped like a pear and not a sphere
That different places receieve different amounts of solar energy
That different places receive different amounts of wind
That different places receive different amounts of thermal energy
The amount of moisture in the soil
The amount of precipitation in the area
The human population in the area
The amount of solar energy recieved by the area
The elevation of the area
It includes the average temperature of that locality
It contains at least one community
It includes bacteria and fungi
It includes chemical resources
All of the above are true about an ecosystem

The angle of the sunlight is an important determinant of the amount of solar energy received
The density of vegetation affects how much solar radiation a place will receive-- the more grassland, the less solar radiation
The density of vegetation affects how much solar radiation a place will receive---the more tall trees, the less solar radiation
The heigh of a place above sea level is an important determinant of the amount of solar energy that place receives
The winds of upper stratosphere can blow solar radiation away from an area before it reaches the land
Consume carnivores primarily
Rely on symbiotic bacteria living in their digestive systems to help digest cellulose
Consume herbivores primarily
Rely directly on primary producers for energy
Are more common than secondary consumers
False; food chain depends solely on population size
True; food chains accurately illustrate existing trophic levels
False; food chains depict organisms diets, not energy flow
True; however they do not represent the amount of energy flowing through the ecosystem
False; real ecosystems are much more complex than simplified food chains

Is lower than when the sun is high in the sky because the solar rays strike more atmospheric molecules on its way to the earth
Is lower than when the sun is high in the sky because the same amount of solar radiation is subject to greater temperature fluctuations
Is higher than when the sun is high in the sky because the same amount of solar radiation is being spread over a large area
Is lower than when the sun is high in the sky because the same amount of solar radiation is being spread over a large area
Is higher because the energy has built up during the day
