Environments high in this have many different species living in the area.
What is biodiversity?
The number of a species in a given area.
What is population size?
An organism that consumes other organisms for energy is called this.
What are Predator, Heterotroph, Secondary+ Consumer?
Organisms that eat primary consumers.
What are secondary consumers?
The producers go here on the energy pyramid.
What is the bottom?
A density-dependent factor, where hunters kill and eat their prey.
What is predation?
How close the individuals of a population are to each other.
What is population density?
Organisms that make their food from the sun or inorganic material.
What are autotrophs or producers?
Herbivores are considered this type of consumer.
What is a Primary Consumer?
In food chains, the arrows represent this.
What is the flow of energy?
A density-dependent factor, where organisms are fighting for the same resources.
What is competition?
When individuals of a species join a new population.
What is immigration?
Organisms that eat dead material.
What are decomposers, detritivores, or scavengers?
Organisms that perform photosynthesis and cellular respiration.
What are producers?
A squirrel eats oak tree acorns. In a food web/chain, the arrow would point towards this organism.
What is the squirrel?
A species that has an outsized effect on the ecosystem.
What is keystone species?
In population ecology, this type of growth has a "J" curve.
What is exponential growth?
Organisms that eat many types of organisms, producers and consumers.
What is an omnivore?
Photosynthesis is performed by producers and makes these products.
What is glucose (C6H12O6) and oxygen (O2)?
A producer has 400 units of energy. Given the 10% rule, a primary consumer can get this much energy.
What are 40 units of energy?
These are examples of density-independent limiting factors.
What is weather or natural disaster? (more specific answers accepted)
The flat line on an "S" curve of logarithmic population growth, where births equal deaths, is called this.
What is carrying capacity?
In order to access storage energy (glucose) and convert it to useable energy (ATP), all organisms perform this function.
What is cellular respiration?
In the 10% rule, an organism only captures about 10% of the energy from their food source. The other 90% is lost to this.
What is heat?
A producer has 1100 units of energy. Given the ten percent rule, the secondary consumer can get this much energy.
What is eleven units of energy?
