Use pictures or words and arrows to show straight-line trophic relationships.
What are food chains?
100
The general term for when species within a community develop close interactions.
What is symbiosis?
100
These are at the base of the Energy Pyramid.
What are primary producers?
100
The process of change over time.
What is Evolution?
100
Also known as "Survival of the Fittest".
What is Natural Selection?
200
In this example, the arrow should point in this direction: tertiary consumer ------- secondary consumer
What is to the left?
200
When a lion eats an antelope illustrates this type of symbiotic relationship.
What is predation?
200
This term describes the positions organisms occupy on the energy pyramid.
What are trophic levels?
200
A sequence of DNA that codes for specific traits.
What is a gene?
200
Selection under human direction.
What is Artificial Selection?
300
These are interconnected food chains that illustrate the complexity of relationships in an environment.
What are food webs?
300
A tick gets a blood meal from your pet dog illustrates this type of species interaction.
What is parasitism?
300
This percent of energy is passed along as you move one level up the energy pyramid.
What is 10%.
300
A change in a population's gene pool over time.
What is biological evolution?
300
The term for a trait that evolves to allow an organism to better survive.
What is adaptation?
400
This would happen to a population of mice if owls were eliminated from this food chain: grass -----> mice -----> owls
What is it would increase?
400
The use of the same limited resource by two species in a community causes this type of species interaction.
What is competition?
400
In addition to illustrating the reduction of available energy at each trophic level, an energy pyramid can also tell this about the population of organisms occupying those levels.
What is their relative population size?
400
Evolution that occurs by chance.
What is Genetic Drift?
400
All the genes present in a population.
What is the Gene Pool?
500
Herbivores occupy this trophic level.
What is trophic level 2?
500
Bacteria in our gut help us to digest our food, while enjoying the protection from things that may harm it. This statement is an example of this type of symbiotic relationship.
What is mutualism?
500
If a population of secondary consumers has an energy level of 352.68 kcal, this is how much energy is in the primary producer population.
What is 35268 kcal?
500
Mutation, Migration, Genetic Drift and Natural Selection drive evolution and are called this.
What are the Mechanisms of Evolution?
500
Organisms produce more offspring than can survive; Individuals vary in traits, some of which are heritable; Individuals vary in fitness, or reproductive success; these statements describe the ______ of Natural Selection.
