DEBio 45b Quizs

fixed action pattern

• A series of random movements triggered by a stimulus

• A series of movements completed after a stimulus, even if the stimulus is removed

• An instinctive behavior that occurs without prior experience

• A learned behavior that requires practice and reinforcement

parasitism

• type of symbiosis where both species benefit

• type of symbiosis where one species benefits and the other is harmed

• type of symbiosis where both species are harmed

• type of symbiosis where one species is unaffected

community ecology

• studies how populations of different species interact in the same habitat

• focuses on the physical characteristics of a habitat

• examines the genetic variations within a single species

• analyzes the evolutionary history of a species

imprinting

• a process of rapid, age-dependent learning by copying a trusted individual

• a method of memorizing information through repetition

• a technique for developing critical thinking skills

• a form of learning that occurs only in adulthood

secondary succession

• when a community develops from remnants of the original community

• when a community is established in a previously uninhabited area

• when a community undergoes a complete change in species composition

• when a community is disrupted by a natural disaster

What are physical defenses against predation and herbivory?

• Camouflage and mimicry that confuse predators

• Bright colors that attract herbivores

• Physical defenses include appearances that make it hard to find or fool an animal into thinking it's toxic.

• Chemical defenses that repel all animals

Mullerian mimicry

• when multiple toxic species are colored like each other

• when a harmless species mimics a toxic species

• when species evolve to look like their environment

• when different species share the same habitat

mutualism

• type of symbiosis where both species benefit

• a relationship where one species benefits and the other is harmed

• a type of competition between species

• a relationship where both species are unaffected

climax community

• transitional community with low biodiversity

• mature, stable community with high biodiversity

• temporary community with fluctuating species

• community dominated by a single species

What is predation in community ecology?

• A relationship where two species compete for the same resources.

• A process where one species eats another, leading to predator-prey cycles.

• A mutualistic interaction between two species that benefits both.

• A phenomenon where species coexist without interacting.
