BIO 156 Final Test Questions with Verified
Correct Answers
What is the definition of Biology?
Biology is the scientific study of life and living organisms, encompassing various fields that
explore the structure, function, growth, origin, evolution, and distribution of living
organisms.
How is biology hierarchically organized?
Biology is organized into a hierarchy that includes levels such as molecules, cells, tissues,
organs, organisms, populations, communities, ecosystems, and the biosphere.
What is the definition of Ecology?
Ecology is the branch of biology that studies the interactions between organisms and their
environment, including both biotic (living) and abiotic (non-living) factors.
What hierarchical levels of biology do ecologists usually focus on?
Ecologists typically focus on levels such as populations, communities, ecosystems, and the
biosphere.
What are abiotic factors?
Abiotic factors are the non-living chemical and physical components of the environment,
such as temperature, water, sunlight, soil, and air.
What are biotic factors?
Biotic factors are the living components of an ecosystem, including plants, animals, fungi,
and microorganisms.
What is the difference between intraspecific and interspecific interactions?
, Intraspecific interactions occur between individuals of the same species, while interspecific
interactions occur between individuals of different species.
What is the definition of Evolution?
Evolution is the change in the heritable characteristics of biological populations over
successive generations, driven by processes such as natural selection, mutation, and genetic
drift.
What is Microevolution?
Microevolution refers to small-scale evolutionary changes within a population, often
involving changes in allele frequencies over time.
What is Macroevolution?
Macroevolution refers to large-scale evolutionary changes that occur over long periods,
leading to the emergence of new species and higher taxonomic groups.
What is organismal ecology?
Organismal ecology is the study of individual organisms and their interactions with the
environment, focusing on adaptations and responses to abiotic and biotic factors.
What is the difference between acclimation and adaptation?
Acclimation is a short-term physiological response of an organism to environmental changes,
while adaptation is a long-term evolutionary process that enhances survival and reproduction
in a specific environment.
What is an Ecological Niche?
An ecological niche is the role and position a species has in its environment, including its
habitat, resource use, and interactions with other organisms.
