Sheet Questions & Answers
Properties of Life - ANSWERSOrder, Evolutionary Adaptation, Response to the
Environment, Regulation, Energy Processing, Growth and Development, Reproduction.
Exploring Levels of Biological Organization - ANSWERSEcosystems - living and
nonliving components of a specific area
Communities - a variety of organisms inhabiting an ecosystem
Populations - one species that inhabits a specific locale
Organisms
Organs and organ systems
Tissues
Cells
Organelles
Molecules
Biosphere - ANSWERSConsists of all life on Earth and all parts of the Earth in which life
exists, including land, water, and the atmosphere. Vancouver Island Ex: Earth
Ecosystem - ANSWERSA biological community of interacting organisms and their
physical environment. Vancouver Island Ex: temperate rain-forest
Communities - ANSWERSAll the different populations that live together in an area.
Vancouver Island Ex: forest of trees and undergrowth plants, inhabited by animals and
rooted in soil containing bacteria and fungi
Populations - ANSWERSgroups of individuals that belong to the same species and live
in the same area. Vancouver Island Ex: Fir trees, Fish, Berry shrubs, Bears, Wolves
Organism - ANSWERSAn individual living thing. Vancouver Island Ex: American Black
Bear
Organs - ANSWERSA structure consisting of several tissues adapted as a group to
perform specific functions. Vancouver Island Ex: Salmon's heart,liver,stomach,gills
exposed after a bear tears into them.
Tissues - ANSWERSgroups of similar cells that perform a specific function in an
organism. Vancouver Island Ex: Salmon Muscle Tissue exposed after bear tears into
them.
Cells - ANSWERSBasic unit of life
,Organelle - ANSWERSA tiny cell structure that carries out a specific function within the
cell
Molecule - ANSWERStwo or more atoms held together by covalent bonds
Vancouver Island is defined as a ________________.(Ecosystem) -
ANSWERSTemperate Rain-forest
temperate rainforest - ANSWERSThe cool, dense, rainy forests of the northern Pacific
coast; enshrouded in fog much of the time; dominated by large conifers
Give an example of 2 different plants and 2 different animals found in a temperate
rainforest. - ANSWERSPlant A: Douglas Fir Tree
Plant B: Western Hemlock
Animal A: American "Black" Bear
Animal B: Salmon
energy flow - ANSWERSthe flow of energy from an ecosystem to an organism and from
one organism to another. Ex: Sunlight being absorbed and converted to energy via
photosynthesis than that energy is transferred to another organism via plant
consumption by the organism than that energy is released again via the organisms scat
which is absorbed by the decomposers such as fungi and than the energy is released
back into the ground and absorbed back into plants via their roots implanted in the
ground.
Anabolism - ANSWERSConstructive metabolism; the process of building up larger
molecules from smaller ones.
Catabolism - ANSWERSMetabolic pathways that break down molecules, releasing
energy.
Producer - ANSWERSAn organism that can make its own food.
Consumer - ANSWERSAn organism that obtains energy by feeding on other organisms
Decomposer - ANSWERSorganism that breaks down and obtains energy from dead
organic matter
Photosynthesis - ANSWERSprocess by which plants and some other organisms use
light energy to convert water and carbon dioxide into oxygen and high-energy
carbohydrates such as sugars and starches
Give examples of 2 decomposers in the Vancouver Island ecosystem. -
ANSWERSFungi (Mushrooms), Bacteria
, Give examples of 2 consumers in the Vancouver Island ecosystem -
ANSWERSAmerican "Black" Bear, orca "killer" whale
Give examples of 2 producers in the Vancouver Island ecosystem. - ANSWERSSalal
berry plant, Blueberrie plant
Describe the cycle of energy (similar to Fig. 1.9 and 1.10) between these organisms you
listed. - ANSWERSThe sunlight is being absorbed by the Salal berry plant and is
converted into energy via photosynthesis, the plant then produces a berry that is then
consumed by another organism which then absorbs the energy originally produced by
the plant from photosynthesis, once the nutrients are absorbed by the organism that
consumed the plant product the remaining nutrients are then released via the organisms
scat which is then decomposed by either an organism from either a fungal or bacterial
origin, the nutrients are then dispersed back into the environment and reabsorbed by
plant via their roots
Lichens - ANSWERSsmall plants that consist of algae and fungi
Plants - ANSWERSA multicelled photoautotroph, most with well-developed roots and
shoots (e.g., stems, leaves), as well as photosynthetic cells that include starch grains as
well as chlorophylls a and b, and polysaccharides such as cellulose, pectin, and lignin in
cell walls. The primary producers on land.
Mosses - ANSWERSsoft, small, green and nonvascular and are found on the ground
near water
How are plants and lichens and mosses the same? - ANSWERSThey all contain
chlorophyll,
What is the function of plants and lichens and mosses in the ecosystem? - ANSWERS?
Theory - ANSWERSwell-tested explanation that unifies a broad range of observations
Evolution - ANSWERSChange in a kind of organism over time; process by which
modern organisms have descended from ancient organisms.
natural selection - ANSWERSA natural process resulting in the evolution of organisms
best adapted to the environment.
descent with modification - ANSWERSprocess by which descendants of ancestral
organisms spread into various habitats and accumulate adaptations to diverse ways of
life
How does evolution account for the unity and diversity of life? - ANSWERSMost
organisms are unified with a common ancestor but do to different communities being in
different climates and environments, the descendants of the ancestors were modified
