What is a stimulus in biological terms, and how does it affect an organism? An external or internal signal that causes a response from an organism A physical change in the environment that remains unnoticed A chemical reaction within cells that produces energy A genetic mutation that alters an organism's behavior

An external or internal signal that causes a response from an organism

Why is communication (signaling behavior) important between organisms? It results in energy production It produces changes in behaviors of other organisms It leads to genetic mutations It causes physical changes in the environment

It produces changes in behaviors of other organisms

Which of the following are examples of different communication methods in organisms? Mechanical, optical, acoustic, magnetic, thermal Genetic, metabolic, enzymatic, hormonal, cellular Visual, audible, tactile, electrical, chemical Physical, chemical, thermal, nuclear, gravitational

Visual, audible, tactile, electrical, chemical

What are the differences between innate and learned behavior in organisms? Innate behavior is learned through experience; learned behavior is genetic Innate behavior is genetically controlled; learned behavior results from experience Both innate and learned behaviors are genetically controlled Both innate and learned behaviors result from environmental factors

Innate behavior is genetically controlled; learned behavior results from experience

What is the benefit of cooperative behavior seen in some species? It causes a reduction in reproductive success It leads to increased competition for resources It decreases the genetic diversity within a population It increases the fitness of individuals and survival of the population

It increases the fitness of individuals and survival of the population

How do endotherms and ectotherms regulate body temperature differently? Endotherms use metabolic energy; ectotherms rely on environmental heat Both endotherms and ectotherms rely on environmental heat Both endotherms and ectotherms use metabolic energy Endotherms rely on environmental heat; ectotherms use metabolic energy

Endotherms use metabolic energy; ectotherms rely on environmental heat

What is the relationship between body size and metabolism in organisms? Smaller organisms have a higher metabolic rate due to a larger surface-area-to-volume ratio Metabolic rate is inversely proportional to body size Larger organisms have a higher metabolic rate due to a smaller surface-area-to-volume ratio Body size does not affect metabolic rate

Smaller organisms have a higher metabolic rate due to a larger surface-area-to-volume ratio

How do organisms use different reproductive strategies in response to energy availability? Species with many offspring are more energy efficient; species with few offspring are less energy efficient All species use the same reproductive strategy regardless of energy availability Reproductive strategies are not influenced by energy availability Species with many offspring are less energy efficient; species with few offspring are more energy efficient

Species with many offspring are less energy efficient; species with few offspring are more energy efficient

What roles do autotrophs play in food chains and webs, and what are the two types? Autotrophs store energy in chemical bonds; types include lipids and carbohydrates Autotrophs decompose organic matter; types include fungi and bacteria Autotrophs consume other organisms; types include herbivores and carnivores Autotrophs capture energy from the environment; types include photoautotrophs and chemoautotrophs

Autotrophs capture energy from the environment; types include photoautotrophs and chemoautotrophs

What are the roles of different types of consumers/heterotrophs in food chains and webs? Herbivores feed on producers; carnivores feed on consumers; omnivores feed on both; decomposers break down organic molecules Herbivores feed on decomposers; carnivores feed on omnivores; omnivores feed on producers; decomposers feed on carnivores Herbivores feed on consumers; carnivores feed on producers; omnivores feed on decomposers; decomposers feed on omnivores Herbivores break down organic molecules; carnivores feed on both producers and consumers; omnivores feed on decomposers

Herbivores feed on producers; carnivores feed on consumers; omnivores feed on both; decomposers break down organic molecules
