First, second, and third
What is a community?

An organism that can make its own food
The amount of organic compounds produced by an ecosystem
All of the same species in the same area
What is biomass?
How heavy the world is
The highest level of organization
All the organic material produced by an ecosystem
A mass of all living species in an environment
Which of the following is a correct statement about the energy flow of food pyramids?
More energy gets transferred as you go up the pyramid
Energy is never lost going from level to level
The tertiary consumers get the most energy
Energy gets used by the organism so less gets passed on

It is the growth of a community in an area that has no soil
It is the second plant in a community
Which of the following is a difference between logistic and exponential growth?
The logistic model is truer than the exponential model
The logistic is S shaped and the exponential is J shaped
The logistic model accounts for carrying capacity
All of the above are differences
The number of individuals an environment can support over a period of time is knows as:
Limiting factors
Biomass
Carrying Capacity
Population Growth
What is commensalism?
Where one species benefits and the other has no affect
Where one organism is harmed and the other is helped
Where both species are helped
When two species are using the same resource
What is mutualism?
Where one species benefits and the other has no affect
Where one organism is harmed and the other is helped
Where both species are helped
When two species are using the same resource
What is parasitism?
Where one species benefits and the other has no affect
Where one organism is harmed and the other is helped
Where both species are helped
When two species are using the same resource
