Abiotic Factors

Biotic Factors

  • Abyssal food chain
  • Location
  • Climate
  • Limiting Factors

Climate

  • in the abyss, water tends to be just above freezing (35°F)
  • Although the water is cold, hydrothermal vents push heated water (750°F) up from beneath the ocean floor.

The Abyssal Food Chain

Location

  • Since there is no sunlight in the abyssal zone, plants are not the main producers. Instead, chemo-synthetic bacteria that receive energy from Hydrogen and Carbon Dioxide , and is the only producer to provide energy for primary consumers.
  • located in the deeper parts of the ocean.
  • high pressure.
  • too deep for sunlight to reach.

Limiting Factors

  • lack of sunlight
  • lack of heat
