Terrestrial and Aquatic Biomes 1.2-1.3 Flashcards
Biomes
Large regions of the earth that are characterized by climate conditions
Terrestrial Biomes are defined by annual _____ and _____
Temperatures and precipitation
How much salt there is in a body of water determines which species can survive and usability for drinking
Salinity
Determines which plants and organisms can survive, how much O2 can dissolve into H2O
Flow
Warmer water holds less dissolved O2 so it can support fewer aquatic organisms
Temperature
Influences how much sunlight can penetrate and reach plants below the surface for photosynthesis
Depth
Have high O2 due to flowing mixing H2O and air, also carry nutrients rich sediments
Rivers
Standing bodies of fresh H2O
Lake
Shallow water with emergent plants
Littoral
Where light can reach (no rooted plants)
Limnetic
Too deep for sunlight (No photosynthesis)
Profundal
Murky bottom were bugs live, nutrient rich sediments
Benthic
Area with soil submerge saturated in water for at least part of the year, but shallow enough for emergent plants. Plants living here have to be adapted to living with roots submerged in standing water
Wetland
Benefits of wetland
- Stores excess water during storms, lessening floods
- Recharges groundwater by absorbing rainfall in to soil
- Roots of wetland plants filter pollutants from water draining through
- Highly plant growth due to lots of water and nutrients
Area where rivers empty into the ocean. Mix of fresh and saltwater. High productivity
Estuaries
Estuary habitat along coast and temperature climate. Breeding ground for many fish and shellfish species
Salt marsh
Estuary habitat along coast of tropical climates.
Mangrove swamps
Narrow band of coastline between high and low tides. Organisms must be adapted to survive crashing waves and direct sunlight and heat during low tide
Intertidal zones
Warm shallow waters beyond the shoreline. Most diverse marine biome on earth. Mutual relationships Between coral and algae.
Coral reefs
Low productivity area as only phytoplankton can survive in most of the ocean.
Photic zone = Area where is sunlight can reach
Aphotic zone = Area too deep for sunlight
Open ocean
