This shape allows us to visualize the way energy moves through an ecosystem.
What is a pyramid (or triangle)?

Barnacles tend to grow on whales skin and use the movement of the whale to filter feed. The whale is totally unbothered by this while the barnacle benefits. This is an example of what kind of symbiotic relationship?
What is commensalism?
200
This is the level that organisms can be classified into on an energy pyramid.
What is a trophic level?
200
Ecologists use this model to represent the many complex feeding relationships that are present in an ecosystem.
What is food web?
200
While an ecosystem accounts for all biotic and abiotic factors in an area, this accounts just for the biotic factors in an area.
What is community?
300
Why do ecologists use mathmatical models when examining populations?
What is to make predictions about how a population will change over time and respond to different conditions?

Hopefully your friendships follow this type of symbiosis, meaning you both benefit from the relationship.
What is mutualism?
300
Most energy pyramids begin with this as their original source of energy.
What is the sun?

Autotrophs always occupy this trophic level in a food web.
What is producer level?
300
This describes an organism's specific job or role in an ecosystem.
What is a niche?
400
Populations eventually reach this when they are affected by limiting factors.
What is carrying capacity?
400
The relationship between humans and the bacteria that lives in their intestines could be described as this type of symbiotic relationship.
What is mutualism?
400
This rule describes the amount of energy that is conserved from trophic level to trophic level.
What is the rule of 10 (or the 10% rule)?
400
Herbivores always occupy this level in a food web.
What is primary consumer level?

The effect of this limiting factor is directly impacted by how many organisms are living in a given area.
What is a density-dependent limiting factor?
500
This organism is generally smaller than its host.
