Diversity Q1 Flashcards
unicellular
made up of one cell, no tissues
heterotrophic
cannot produce its own energy, ingests other living things to produce energy
aerobic respiration
when energy is produced by breaking down sugar, w/ oxygen
sexual reproduction
reproduction with male and female gametes in a process called fertilization
multicellular
made up of many cells, has tissues
autotrophic
able to produce its own energy from the suns light energy
anaerobic respiration
energy is produced by breaking down sugars, happens w/o oxygen
asexual reproduction
reproduction by mitosis or binary fission
genetic diversity
genetic variety within a particular species
species diversity
variety and abundance of species in a given area
ecosystem diversity
variety of ecosystems in the biosphere
more diversity
healtheir environment
ecosystem services
benefits provided from sustainable ecosystems (e.g. water supply, food production)
greater species diversity means that the ecosystem is more resilient to disturbances such as:
non native species invasion, disease, changes in abiotic factor concentrations
anatomical evidence
study of structure and form of organisms to determine evolutionary relationships between speces
physiological evidence
physical and chemical functions of an organism (biochemistry and internal processes), prov. ex.
dna evidence
conductin genetic analysis, dna can be used to compare relationships b/w species, provide ex.
Carolus Linnaeus
father of taxonomy contributed a hierarchical classification system
taxons (largest –> smallest)
kingdom, phylum, class, order, family, genus, species
taxons used for binomial nomenclature
genus + species
7 fundamental characteristics of life
metabolism, offspring, response, growth, homeostasis, excretion, nutrition
virus
pathogens that are not considered “alive” since they cannot live outside of cells
not classified as a kingdom of life and not considered living organisms because
- cant reproduce on their own and is dependent of internal physiology of cells
- not cellular, lack cytoplasm, organelles and cell membrane
host
organism that carries the virus
