It's Alive!
This is the word for the living factors of an ecosystem
What is biotic?
This is an example of a density-dependent limiting factor of population size.
What is a resource? such as food, water, space, light etc
This is the name of the relationship between two species that benefits both
What is mutualism?
This is a species that evolved in the environment where it lives.
What is a native species? (or indigenous)
This is the term that describes how many different species live in an ecosystem.
What is species diversity?
This is the word for non-living components of an ecosystem.
What is abiotic?
This is an example of a density-independent limiting factor of population size.
What is a natural disaster? such as a flood, forest fire, volcanic eruption, etc.
This is the name of the relationship between two species when one organism lives off of a host and harms the host.
What is parasitism?
This is the gradual process of an ecosystem developing on brand new land.
What is primary succession?
This is a group of organisms of the same species, in the same place, at the same time.
What is a population?
This is the part of the line you look for on a graph to determine carrying capacity.
What is a plateau? or where the rising line levels off?
This is the amount of energy taken in at one trophic level that is available to the next trophic level.
What is 10%?
These are two examples of pioneer species that can grow on bare rock and build soil.
What are mosses and lichens.
This is all of the populations in an ecosystem.
What is a community?
This is one of the similarities between introduced and invasive species, and one of the differences.
What is they both come from a different habitat (they are non-native) but an invasive species causes harm while an introduced species does not.
When one organism benefits and the other is not helped or harmed.
What is commensalism?
A flood destroys an ecosystem and a new ecosystem grows in its place. This is the name of that process.
What is secondary succession?
The entire portion of the Earth that supports life.
What is the biosphere?
This is the definition of carrying capacity.
What is the maximum population size of a single species that an ecosystem can sustain?
This is the pattern you should see in a predator-prey graph.
What is the prey population should increase before the predator population increases and prey population should decrease before the predator population decreases.
These are three characteristics of most invasive species.
What are successful/rapid reproduction, no natural predators, adaptable to many habitats/conditions, out competes native species
Scientists estimate population size and species diversity by sampling organisms in an ecosystem. Name three of these sampling methods.
Transect, quadrat, mark and recapture, removal sampling
