Exam Questions and Solutions
What are the characteristics of living things? ✅Response to Surroundings,
reproduction, growth and development, DNA, obtain and use energy, and cell
organization
What are the three parts of the cell theory? ✅All living organisms are composed of
cells, the cell is the basic unit of life, and cells arise from pre-existing cells.
What are the levels of organization of living things? ✅Organelle, cells, tissues, organs,
organ systems, organisms, populations, communities, ecosystem, and biosphere.
What is homeostasis? ✅Dynamic process through which the body maintains blanace
by adjusting internal and external stimuli.
What are 3 types of symbiotic relationships? ✅Mutualism, commensalism, and
parasitism
What is biogeochemical cycling and circulation of nutrients in the biosphere? ✅A
pathway by which a chemical substance moves through both the biotic (biosphere) and
abiotic (lithosphere, atmosphere, and hydrosphere) components of Earth.
What is the importance of legumes and their role for nitrogen cycling? ✅In the nitrogen
cycle, legumes form a symbiotic relationship with certain types of bacteria that are
involved in a process known as "nitrogen fixation." The legumes provide the
microorganisms with the required energy to initiate the process, while the bacteria fixes
captured nitrogen from the air into a usable form, which is absorbed by the legumes for
sustenance.
What are the main processes that cycle carbon through the biosphere? ✅The Carbon
Cycle,
What is the role role of bacteria in nutrient cycling? ✅Decompose organic matter and
make nutrients available for plants.
What is the difference between habitat and niche? ✅A habitat is where an organism or
a community of organisms lives, and a niche is the specific place an organism has in an
ecosystem. A habit can help define the niche of particular creature but cannot describe
it entirely.
, What is the difference in the organizational levels of an ecosystem? ✅A species is a
group of individuals that are genetically related and can breed to produce fertile young.
Individuals are not members of the same species if their members cannot produce
offspring that can also have children. The second word in the two word name given to
every organism is the species name. For example, in Homo sapiens, sapiens is the
species name.A population is a group of organisms belonging to the same species that
live in the same area and interact with one another.A community is all of the populations
of different species that live in the same area and interact with one another. A
community is composed of all of the biotic factors of an area.An ecosystem includes the
living organisms in an area and the non-living aspects of the environment. An
ecosystem is made of the biotic and abiotic factors in an area. The biosphere is the part
of the planet with living organisms. The biosphere includes most of Earth, including part
of the oceans and the atmosphere.
What is an organism? ✅An organism is a living entity composed of many interrelated
components that work together to achieve a common goal. Organisms come in a wide
variety of sizes, shapes and lifestyles, but they all share some similar traits. All
organisms require food and excrete waste, grow, reproduce and, ultimately, die.
What is the predator-prey interaction? ✅A predator is an organism that eats another
organism. The prey is the organism which the predator eats.
What is the comparison of the movement of matter and energy? ✅Matter is recycled
within and between ecosystems. Energy flow is a one-way flow.
What is the pattern of energy available in a food web? ✅Less energy is available as
the food web goes up.
What are trophic levels? ✅Each of several hierarchical levels in an ecosystem,
comprising organisms that share the same function in the food chain and the same
nutritional relationship to the primary sources of energy.
What is a consumer? ✅Consumers are organisms of an ecological food chain which
receive energy by consuming other organisms.
What is a producer? ✅Producers are organisms that make their own food
What is a autotroph? ✅An organism that is able to form nutritional organic substances
from simple inorganic substances such as carbon dioxide.
What is a heterotroph? ✅An organism deriving its nutritional requirements from
complex organic substances.
What is a primary consumer? ✅The second trophic level.
