Although we think of land when we hear the word biome, there are also aquatic biomes. The abiotic factors that influence life fo
rms vary with location in the ocean. Oceanographers divide the ocean into five broad vertical zones as seen in the chart. Compare the abiotic characteristics of the five ocean zones. Which of these conclusions about life forms found in the zones is supported by the information in the chart? A) Because of the severe abiotic conditions, there are no life forms found in the hadalpelagic zone.
B) The epipelagic zone is the only zone of the five zones where visible light and algae can be found.
C) The mesopelagic zone hosts a diverse zooplankton community instead of a phytoplankton or algae community and virtually no fish species.
D) Because there is no light in the abyssal zone, organisms feed on each other or the dead organic material, detritus, that falls into the abyssal zone from above.
Hadalpelagic zone contains life such as amphipods
, snailfishes and cusk-eels.
Epipelagic zone is the ONLY zone where visible light and algae can be found. Lower than that the amount of light is insufficient for plants to carry out photosynthesis.
The mesopelagic zone has a diverse biological community that includes unique organisms adapted to live in a low-light environment including fish like
the blobfish, bristlemouths or the tasselled anglerfish.
The probability is 1/16 that a gamete will receive only paternal chromosomes. In life
cycles that alternate between haploid and diploid stages, fertilization doubles
the number of chromosomes per cell, The pairing of chromosomes along
their lengths , which is essential for crossing over is referred to as synapsis
