Butterflies land on flowers to eat their nectar, and take with them the pollen to other flowers (helping to pollinate the flowers). This is an example of what type of symbiosis?
Mutualism.
100
A relationship between any two biological species is called...
Symbiosis (or symbiotic relationship).
100
A biological interaction where a predator attacks or feeds on it's prey is called...
Predation.
100
Humans exhibit what type of survivorship curve?
Type I - most of the offspring survive into adulthood as a result of high parental involvement.
100
What dispersion pattern to penguins exhibit when they are evenly spaced from one another, defending their nests?
Uniform dispersion.

A tick (insect) lands on a dog and bits into its skin. It begins to suck its blood, taking it as nutrition. The dog does not realize that it has a tick. What is this an example of?
Parasitism.
200
When 2 or more organisms compete for the same resources (like water, food, or habitat), it is called ...
Competition.

Complete this sentence... "As they prey population grows, the predator population..."
Grows as well. (Predator feeds off prey. More food = more growth.)
200
Species that have: - a large number of offspring - small body size - early maturity - little parental care - unstable environment are called...
r-related species (or r-strategists)

What dispersion pattern do grizzly bears exhibit when they are in the forest foraging (looking) for food on their own?
Random dispersion.

A python stalks and attacks a field mouse. It grabs it whole and swallows it by unhinging its jaw. The mouse dies and the python gets lunch :) What is this an example of?
Predation.
300
A biological interaction in which 2 species benefit by having a symbiotic relationship is called...
Mutualism
300
We saw that as the wolf population increased as a result of more deer to eat, the deer population began to ...
Decrease rapidly (nearly back to the beginning point).
300
Species that have: - large body size - few offspring - high parental care - long life-span - stable environment are called...
K-related species (or K-strategists)

What is an example of commensalism in your life? Be specific.
Answers will vary.
400
A cattle egret (a type of bird) follows around cows and eats the insects that the cows kick up as they move around eating the grass. What is this an example of?
Commensalism.
400
A biological interaction between 2 species in which one specie benefits while the other is neither harmed nor hurt is called...
Commensalism
400
Give an example of a predator-prey relationship. Identify who is the predator, and who is the prey.
Answers will vary.
400
The maximum population size that an environment can sustain given food, water, and habitat needs of the species is called...
The carrying capacity.
400
What type of dispersion pattern do fish exhibit when they are swimming in a school?
Clumped dispersion.
500
A lion and a cheetah both go after a gazelle in the plains of Africa. Sometimes the lion gets to eat the gazelle, and other times the cheetah wins the gazelle. What is this an example of?
Competition.
500
An interaction between two species in which one species benefits by feeding off of another's nutrition, habitat or body. Usually the host species is not killed, but is still harmed by losing nutrition or habitat. This is called...
Parasitism.
500
How is predation both similar to and different from parasitism?
Predation is a relationship in which one organism preys on another. Parasitism is a relationship in which one organism also benefits while the other is harmed. They are different because in predation, the predator usually kills its prey, while in parasitism, the parasite does not usually kill its host.
500
When a population is growing with seemingly no end to available resources (like water, food, and shelter), it is called ...
Exponential growth.

What is the difference between a generalist and a specialist? Which one would most likely survive drastic changes in their environment (like from global warming)?
A generalist is a species that can eat multiple types of food (like a raccoon) while a specialist only eats a single type of food (like a koala). A generalist will most likely survive drastic changes over a specialist because even if one type of their food is wiped out, they have other types to get nutrition from.
