Decomposers
What does adaptation mean?
The behaviors and physical characteristics that allow organisms to live successfully in their environments.
A series of events in an ecosystem in which organisms transfer energy by eating and being eaten.
What is Parasitism?
An organism living inside or on another organism
If you reduce resources in an ecosystem, what happens?
It could decrease the population of a species.
Which organisms use the sun’s energy and make it available to other organisms?
Producers
WHat does survival mean?
The behaviors and physical characteristics that allow organisms to live successfully in their environments.
These organism can eat a variety of plants or other animals as seasons and habitat conditions change. These organisms are called generalists and can spread over large areas.
Broad niche
What is an adaptation?
Help organisms survive, compete or avoid competition and can be structural or behavioural
What number can be used to check the health of an ecosystem and how do we calculate it?
Diversity Index = #diff. speci./#of spec.
A species that only eats vegetation.

What helps to keep an ecosystem diverse or varied?
Genetic varation
What is a keystone species?
an organism that helps define an entire ecosystem.
Something in an ecosystem that is non-living.
Abiotic factor
Organisms that eat other organisms to meet their food needs.
What is biodiversity within species mean?
Variation between individuals of the same type of living thing
Adaptation by competing species resulting in the subdivision of an area so these species can coexist with less competition
Resource Partitioning
What is niche diversity?
When an ecosystem has many different species that belong to different niches, which balances healthy ecosystems.
The number of genes within a population affects the species' ability to survive. If there is a high ____________ ____________, then the species will have a greater ability to survive changing environmental conditions.
