threats of biodiversity
habitat loss, habitat fragmentation, edge effect, habitat degradation, acid rain, ozone hole, introducing exotic species
organism that represents a feeding step in the movement of energy and materials through an ecosystem
organisms that use energy from the sun or energy stored in chemical compounds to manufacture own needs
limiting factors that effect growth of population (ex: disease, parasites, food availability)
factors that affect all populations, regardless of their density (ex: temperature, storms, floods)
group of prokaryotes with strong cell walls and a variety of structures, may be autotrophs
chemosynthetic prokaryotes that live in harsh environments, such as deep sea vents and hot springs
group of unicellular or multicellular heterotrophic eukaryotes that do not move from place to place
viral replication cycle in which virus takes over a host cell's genetic material and uses the host cell's structures and energy to replicate until the host cell bursts, killing it
viral replication cycle in which the virus's nucleic acid is integrated into the host cell's chromosome
type of viral replication where virus uses reverse transcript to make DNA from viral RNA; DNA is then integrated into the host cell's chromosome
viral DNA that is integrated into a host cell's chromosome and replicated each time the host cell replicates
asexual reproductive process in which one cell divides into two separate genetically identical cells
form of sexual reproduction in some bacteria where one bacterium transfers all or part of its genetic material to another through a bridge like structure called a pilus
autotrophic process where organisms obtain energy from the breakdown of inorganic compounds containing sulfur and nitrogen
tiny structure that contains a bacterium's DNA and a small amount of its cytoplasm, encased by a tougher outer covering that resists drying out, temperature extremes, and harsh chemicals (resting state)
type of asexual reproduction in algae where an individual breaks into pieces and each piece grows into a new individual
diverse group of multicellular or unicellular eukaryotes that lack complex organ systems and live in moist environments
alteration of generations
haploid forms gametophyte, gametophyte fuse and form diploid zygote, sporophyte undergoes myosis and form haploid gametophyte
water mold/ downy mildew
Live in water or moist places, Feed on dead organisms or are parasites, Look like fuzzy white growths on decaying matter
in parasitic fungi, hyphae that grow into host cells and absorb nutrients and minerals from host
Mitosis occurs and new individual pinches off from the parent, matures and separates from the parent
