Biology 1407 Exam test quizzes and
answers graded A+
Define and give an example predation - ANS✅✅****symbiotic relationship between two
organisms in which one acts as a predator that captures and feeds on other organisms that serve as
the prey (Trophic)(+,-)
Ex: cat and mouse
Define and give an example competition - ANS✅✅Individuals compete for a resource that limits
their growth and survival
****(Can be over sunlight, water, food ,space, nest sites)
****Example: weeds in garden compete with garden plants for water, grasshoppers & bison
compete for grass
Define and give an example ammensalism - ANS✅✅one is unaffected and the other is damaged or
destroyed(0,-)
****Example: elephant/flora (Non-Trophic), understory plants(Trophic)
Define and give an example of trophic relationships* - ANS✅✅Trophic: involves feeding
relationships
Ex: predation (+ / -);
Define and give an example of non-trophic relationships* - ANS✅✅Non-trophic: involves non
feeding relationships
Ex: ammensalism (- / 0); elephant & flora; competition (-/-)
Define and give an example of a carnivore - ANS✅✅Predator and prey are both animals and the
prey loses its life (type of predation)
Ex: cat (predator) and mouse (prey)
Define and give an example of an herbivore - ANS✅✅Predator is an animal and the prey is a plant
or algae (type of predation)
Ex: giraffes
, Define and give an example parasitism - ANS✅✅Symbiotic interaction in which predator is a
parasite and the prey is a host (parasite)
Ex: human and tapeworm
Define and give an example of aposematic color* - ANS✅✅Warning colors that animals with
chemical defenses demonstrate
Ex: frogs
Define and give an example of resource partitioning - ANS✅✅If 2 species share a resource, the
most common mechanism; sharing limited resources by using them in different ways, allowing them
to coexist
Ex: each species of a specific lizard has a preferred perch and rarely strays from it, remove a species
and the others expand to fill that niche
Define and give an example mutualism - ANS✅✅Symbiotic interaction where both species benefit
from the interaction (+/+)
Ex: flowering plants/pollinating insects: insect moves pollen among flowers achieving fertilization,
insect eats some of the pollen/nectar
Define and give an example of commensalism - ANS✅✅Symbiotic interaction where one
participant benefits and the other is unaffected
Ex: bird hole in a tree; vultures and lions
Describe adaptations made by prey and predators, and give examples - ANS✅✅Prey:retreat,
camouflage(crypsis) ,warning coloration, poison, mimicry, spines/thorns, schooling, alarm calls,
shells, hiding
Predator: claws, teeth, fangs, stingers, poison, chemical sensors, speed and agility
What are 2 predator and several prey strategies? - ANS✅✅Predator: venom, intelligence, active
pursuit, sit-and-wait,
Prey: speed to flee, flight, mechanical defenses, avoiding detection, chemical defenses, behavior
(flocks and alarm calls)
What are the 2 types of mimicry? - ANS✅✅Batesian and Mullerian
