Biology 1407 Exam questions and
answers graded A+
Define and give an example predation - ANS✅✅Killing of animals for food
Ex: cat and mouse
Define and give an example competition - ANS✅✅Individuals compete for a resource that limits
their growth and survival
Ex: lions and hyenas
Define and give an example ammensalism - ANS✅✅One is affected, the other is damaged or
destroyed
Ex: elephant and flora
Define and give an example of trophic relationships* - ANS✅✅Ex: predation (+ / -);
Define and give an example of non-trophic relationships* - ANS✅✅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:
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: spines,
thorns, toxins, bad taste
Predator: grinding teeth, tough mouth, tolerance of toxins
What are 2 predator and several prey strategies? - ANS✅✅Predator: venom, intelligence
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
Define Batesian mimicry and give an example - ANS✅✅Harmless species looks like a dangerous
species
Ex: nonpoisonous butterfly vs monarch butterfly
Define Mullerian mimicry and give an example - ANS✅✅2 or more dangerous species resemble
each other
Ex: 2 poisonous butterflies that look exactly the same
