This is what an arrow in a food chain or web represents.

The movement of energy.

100

Symbiosis is defined as the close __________ between multiple organisms of the same, or different species.

Relationship

100

This type of growth pattern resembles a "J".

Exponential Growth

100

Who was the person credited with coming up with the theory of natural selection?

Charles Darwin

100

This is the name for all of the combined alleles of of all of the organisms in a given population.

Gene pool

200

This is where energy is almost every ecosystem comes from.

The sun.

200

This type of symbiosis is where once organism benefits (+), and the other is unaffected (0).

Commensalism

200

This type of growth pattern resembles an "S".

Logistic Growth

200

This is a feature that allows an organism to better survive in its environment.

Adaptation

200

This type of selection occurs when a population shifts towards one of the extreme ends of a phenotype.

Directional Selection

300

This is the general percentage of energy that is passed on between trophic levels.

10%

300

This type of symbiosis is where both organisms benefit from the interaction (+,+).

Mutualism

300
The ________________ __________________ is the upper limit of population size that an ecosystem can contain with the limited resources available, and is found in logistic growth.

Carrying Capacity.

300

This is the measure of the ability of an organism to survive and reproduce in its environment.

Fitness

300

This type of reproductive isolation occurs when organisms have a difference in mating ritual - song or dance.

Behavioral Isolation

400

This is the name for levels of consumers in a food chain or web.

Trophic Levels

400

This type of symbiosis is where one organism benefits (+), and the other organism (the host) is negatively impacted (-).

Parasitism

400

Factors influencing a population such as availability of food/water/shelter, number of predators, disease, and parasites are examples of what kind of factors?

Density Dependent Limiting Factors

400

This evidence for evolution shows structures that are similar, but have different functions which show a common ancestor.

Homologous structure

400

This type of evolution occurs when organisms do NOT have a common ancestor, but end up with similar traits due to their environments.

Convergent evolution

500

This is the name for a 3rd level top consumer.

Tertiary Consumer

500

_______________ is defined as an interaction between organisms which both require resources that are limited in supply.

Competition

500

Factors influencing a population such as floods, hurricanes, tornados, and forest fires are examples of what kind of factors?

Density Independent Limiting Factors

500

This is the single best way to show relatedness in organisms and evolutionary connections.

DNA/Molecular Evidence

500

Name the 2 types of genetic drift.
