organism
defined as an individual, living creature
the most widely accepted characteristics of an organism
(1) Order, (2) Evolutionary Adaptation, (3) Regulation, (4) Energy Processing, (5) Growth and Development,
Response to the Environment, and (7) Reproduction
Order
structures are comprised of the basic unit of life which is the cell
Life is structured into a developmental hierarchy whereby cells give rise
rise to tissues, tissues to organs, and organs to whole organ systems
Evolutionary adaption
often called generational evolution, specifically refers to smaller, genetic changes that allow for better surviva
organism. For instance, consider camouflage
Regulation
,Living organisms are sensitive to temperature, environmental stresses, pH requirements etc. and go to great
ensure optimal levels are maintained. include shivering to generate body heat in humans or the regulation of
through an organism.
Energy Processing
In order to sustain life, biochemical reactions are utilized. The sum of these biochemical reactions is referred
metabolism
Growth and Development
Perhaps intuitive, a living thing grows, matures, ages, and experiences death.
Response to the Environment
Living things respond through adaption. An adaption is a change or a process that allows an organism to bec
suited for their environment
stimulus
Anything that causes an organism to respond
Reproduction
, living things must have a way of producing new and thriving generations to replace the previous ones.
Sexual reproduction
involves the fusion of two gametes (one from each parent) that will unite and grow into a new offspring
Asexual reproduction
gives rise to new offspring from a single organism
Levels of Biological Organization
biosphere, ecosystems, communities, populations, organisms
Biosphere
broadest level encompassing planet earth and the atmosphere; all capable of sustaining living organisms
Ecosystem
a system of living and non-living things in a region. Grasslands, forests, desserts, tundra, savanna, aquatic re
rainforests, and coral reefs including the plants, organisms, soils, and climate conditions associated are all e
ecosystems.
