As we go up the energy pyramid, energy decreases by _____.

10% of the energy; divide by 10

Symbiosis

A relationship that may exist between two or more organisms of different species when they live and work together (ex: commensalism, mutualism, and parasitism)

Mutualism

Both organisms benefit (+, +)

Commensalism

One benefits, other doesn't (+, 0)

Parasitism

One organism benefits, other is harmed (+, -)

Competition

Struggles with other members of the same population for basic needs (food, water, etc.), mates and territory

Cooperation

When members of the same  or different population work with each other to meet their basic needs

Interdependence

A behavior shown by organisms or populations that rely on each other for basic needs; they need one another for survival

Social hierarchy

An organization system within a group of organisms in which each member is ranked; organisms ranked higher receive more resources than organisms ranked lower

Territorial imperative

A behavior exhibited by animals like birds, fish, reptiles and mammals where they maintain a specific area in which to live (a territory); by protecting their territory they maintain their food and other resources found within

Niche

The role an organism fills in an ecosystem (ex: producer, consumer, etc.)
