habitat

Plants or Producers
An organism that eats only plants.
Herbivore
What is the variety of different organisms living in a certain area?
Biodiversity
Where is the largest reservoir of carbon?
Oceans
The community of organisms that live in a particular area, along with their nonliving surroundings. This includes abiotic and biotic factors.
Ecosystem?
These organisms are herbivores, therefore they are called ______________ consumers.
Primary
The word that describes ALL the living organisms found at each trophic level.
Biotic
This happens when the birth rate is higher than the death rate.
Population increases
This is how carbon dioxide leaves the atmosphere and enters the food chain.
Photosynthesis

Abiotic?
An organism that is killed and eaten by another organism.
Prey
If a shark, a tertiary consumer, requires 3500 calories per day, the number of calories that the phytoplankton, a producer, must be is this.

Decrease
Name one way humans return carbon to the atmosphere.
Burn fossil fuels and breathing
An organism that breaks down wastes and dead organisms and recycles the nutrients back into nature.
Decomposer
This is a way to show how energy in a food web is allocated. Usually there is a large base and a pointed top.
Energy pyramid
This is the reason why there are seldom more than five trophic levels in a food chain.
Energy runs out
This is largest population of any one species that an environment can support.
Carrying capacity
How is carbon found in the atmosphere?
Carbon dioxide
Usually written on one line, this is a series of events in which one organism eats another and obtains energy.
Food chain
What is the percentage of energy LOST as it moves from producer to primary consumer to secondary consumer?
