Biology Chapter 34 - Vocabulary
Terms in this set (34)
the nonliving components of the ecosystem.
The region of the aquatic ecosystem underneath the photic zone - light does not penetrate enough for organism to perform photosynthesis.
The seafloor or the bottom of a freshwater body like a lake, pond, river, or stream.
A defined area of ecologically similar communities of organisms
All of the environments on Earth that support life including regions of land, bodies of water, and the lower atmosphere.
the living components of the ecosystem
All of the organisms living in an ecosystem.
Largest biome which stretches across North America and Asia, also exists at high elevations in temperate latitude which are cooler, long, cold winter followed by short, wet summers, thin and acidic soil, slow decomposition, few nutrients available, some precipitation as snow.
areas of oceans/lakes that have so little oxygen that they cannot support most life
a branch of biology that deals with relationships between organisms and their surroundings
Consists of all organisms living in a certain area and all abiotic factors (physical components) that these organisms interact with.
The biome where a freshwater stream or river and the ocean merge.
the specific environment in which an organism lives, including biotic and abiotic factors
A shallow biome where the waters of an estuary or ocean meet the land (there must be tides).
an array of ecosystems that can be defined in an aerial view, for example the divide between the ocean and beach and their different ecosystems
an important element in photosynthesis
continuous, directed movement of sea water
an individual living thing
The region of the aquatic ecosystem that light penetrates, and thus photosynthesis can occur.
Microscopic algae and photosynthetic bacteria (cyanobacteria) that drift passively in aquatic ecosystems.
All the individuals of a certain species living in an ecosystem.
temperate broadleaf forest
Midlatitude, temperatures range from cold winters to hot summers, fairly high precipitation annually that is distributed through the whole year (rain or snow), growing season of 5-6 months, rich soil.
A biome that is between an aquatic ecosystem (can be marine or freshwater) and a terrestrial ecosystem.
Small animals that drift in aquatic ecosystems.
prefix that means without
light (aphotic zone: the region of an aquatic ecosystem beneath the photic zone, where light does not penetrate sufficiently for photosynthesis to occur)
life (biome: a defined area of ecologically similar communities of organisms; biosphere: the part of the Earth inhabited by life; biotic factor: a living component of an ecosystem)
the depths of the sea (benthic realm: a seafloor, or the bottom of a freshwater lake, pond, river, or stream)
the sea (estuary: the area where a freshwater stream or river merges with the ocean)
between (intertidal zone: the shallow zone of the ocean where land meets water)
the sea (pelagic realm: all of the open-water areas of an ocean, excluding the intertidal zone)
remaining (permafrost: a permanently frozen stratum below the arctic tundra)
a plant (phytoplankton: algae and photosynthetic bacteria that drift passively in aquatic environments)
animal (zooplankton: animals [heterotrophs] that drift freely in aquatic environments)
