What is "they are members of the same species"?
In this type of relationship one organism benefits while the other is nierther helped or harmed.
What is commensalism?
This describes the highest number of organisms that an ecosystem can support.
What is carrying capacity?
MOST energy that moves through earth's ecosystems can be traced back to this source.
What is the sun?
This describes that third heterotroph in a food chain/web.
What is tertiary consumer?
Sunlight, weather, soil, and natural disasters are all examples of __________.
What are abiotic factors?
Parasites want to keep these alive as long as possible.
What is the host?
As of today, it is estimated that there is a population of _____________ people on planet earth. (you may round your answer)
What is 8,000,000,000 (8 billion)?
This rule describes the amount of energy that is passed from one organism in a food chain/web to the next.
What is "the 10% rule"?
This level of organization contains both biotic and abiotic factors within an area.
What is an ecosystem?
All organisms in a population have this in common.
What is "they are alive and members of the smae species"?
When an organism is killed by another organism, often as a food source, it is known as _______________.
What is predation?

What is:
1) India
2) China
3) United States
This cosnumer role can NEVER fit into the primary consumer level on a food chain/web. Explain your reasoning.
What is a carnivore? Primary consumers must be able to consume and digest producer which are typically plants.
This is a synonym for consumer.
What is a heterotroph?
These are the levels in order form smallest to largest.
What is "cell -> tissue -> organ -> organ system -> organism -> population -> community -> ecosystem -> Biosphere"?
Two organisms that are vying or working to obtain the same limited resource results in this type of of relationship.
What is competiton?
These have the potential to influence the number of organims living in a population.
What are limiting factors?
This describes each each link in a food chain or web.
What is a trophic level?
Provide three words that would describe an oak tree. (think biology vocab)
What is plant, autotroph, producer.
Explain in your own words why the levels of organization starts with cells and not cell organells.
What is "cell organelles are not capable of life on thier own. Cells are the smallest, most basic units of life"?
These are the three rules that must be followed in order for a relationship to be considered symbiotic.
What is:
1) Must involve at least two different species of organism
2) At least one organism must benefit
3) No organism should die as a direct result
Explain in your own words why symbiotic relationships do not exist within a single population of living things.
What is "they must include at least two different species of organisms"?
Heterotrophs and autotrophs perform cellular respiration in order to turn glucose and oxygen into a usable "fuel" source. What is the goal product of this cell process?
What is ATP energy?
Detritis describes dead organic material. Detritivores is a word that describes an organism that relies on dead organic material as an energy source. What other word would describe the role of these detritivores?
What is a decomposer?
