In a lake, below the compensation depth, net _____ is greater then _____. Respiration; photosynthesis
An ______ chemical is a substance produced by plants or their fungal associates to inhibit the growth of her plants or fungi. allopathic
Most wetland plants have had to evolve some mechanisms to provide _____ to their roots. Oxygen
_____ plants are so named because they are long lived. Perennial
______ plants are plants that complete their entire lifecycle within a year. annual plants
Rubisco enzyme involved in first major step of cellular respiration. Reaction catalyzed by rubisco.
Phenotypic plasticity ability of one genotype to produce one or more phenotype when exposed to different environments
legume family of plants who harbor nitrogen fixing bacteria in their roots. help cover nitrogen into something that can be used by the whole environment
Halophyte salt resistant/tolerant plant who thrives and completes lifecycle in soils or waters containing a high salt concentration.
Photorespiration wasteful pathway that compete with the calvin cycle. Begins when rubisco acts on oxygen instead of carbon dioxide.

Explain mangroves, 3 ecological roles or services they provide live along shore line. (halophyte) ecological roles:1) shoreline protection from damaging storm and hurricane winds 2)prevent erosion by stabilizing sediment in roots 3)maintain water quality trapping sediments + pollutants
are plants capable of exhibiting behavior yes, mycorrhizal networks, mechanisms to help them survive, CAM-> develop defense mechanisms to protect stored water, plants in dry enviro-> waxy cuticle, adapt to enviro by opening and closing stomata
list + explain roles mycorrhizal fungal networks plants connected through fungal network, use it to warn each other to build defense against toxins, tree cut down -> send nutrients to help, sabotage other plants to increase own fitness
diagram Nitrogen cycle Fixation Ammonifaction dentrification Nitrafication dentrification (----)
Most of the suns energy arrives in the form of short wave radiation
solar energy reflected off surface and back to space by albedo
the actual amount of gaseous water in a given body of air is referred to as absolute humidity
solar energy in range of 400-740 nm photosynthetically active radiation
the A horizon layer of soil contains mineral soil combined with organic nutrients
which of the following orders of soils possess thickest O horizons Gelisols
upwellings occur when cold ocean currents collide with terrain features that force them to the surface, introducing a supply of organic matter that fuels some of the most productive oceanic ecosystems in the world
Xeric habitats that are warm and dry
Mesic habitats that are cold and moist
Adiabatic cooling reduction of heat through change in air pressure caused by volume expansion
to reach age of reproduction ticks must successfully pass from the stages of ___ multiple times diapause and questing
Coriolis effect earth rotation causes weather patterns and ocean currents to deflect right in north and left in south
vector agent that carries and transmits an infections pathogen to another organism
density dependent factors factors whose effects onto size of the population cary with the population density
Recruitment additions to population either through birth or immigration
clay smallest of all particles impt microenvironment low friction easily absorbs water
Figure about testosterone added testosterone increase engorgment and survival testosterone increases locomotive activity of ticks, causing them to quest and move around to different hosts
Lifecycle of tick egg-larva-nymph-tick
aposematism organism warns predator they are dangerous
mimicry mimic no prey item
mullarian share both of their warning signs
batesian prey item mimics harmful item
browsers eat wood
coprophagy eat poop
reticulum part of ruminant: where food goes before regurgitated and re digested
heterotherm do both poikilothermy and homeothermy
super cooling animals use to prevent ice formation in their bodies
nephron part of kidney, in cortex, that helps with water conservation
counter-current allows ducks to be able to swim in cold water warm blood blood in arteries Cold water veins <-heat
non-shivering thermogenesis in brown adipose tissue, heat produced in electron transport chain -> instead of it producing ATP it produces heat
salt water fish saltwater concentration higher outside fish-> this sucks water out of fish body (osmosis) saltwater fish excrete sodium chloride by pumping ions across special membranes in the gills
freshwater fish higher salt concentration in body water moves into body salts move outward across gills to balance by absorbing and retaining salts in special cells in the gills, and by producing copious amounts of watery urine
there types of activity patterns nocturnal diurnal repuscular
challenges associated with eating plants different chemical composition : how to convert plant to animal -> plants low in protein and high in carbohydrates (hard to break down)-> carbohydrates locked in indigestible cellulose indigestible cellulose (bacteria and protozoa in gut) ruminants
