Lamprey Ecology

Biome:Salt and fresh water/Marine Charictaristics:

Biotic Factors:
 * Algae
 * Predator Fish
 * Prey Fish
 * Plant matter
 * Coral reafs
 * Microscopic plants and animals
 * Human interference

Abiotic Factors:
 * Bedrock
 * Water
 * Mud
 * Pollutants from urban and agricultural runnoff

Lamprey’s specifically prey on trout, salmon and crayfish. For example, human pollutants from urban and agricultural runoff can get into streams or oceans and cause mutations or diseases among the fish population. Other factors can affect the survival of the fish. Water temperature, pressure and oxygen levels, and currents can also affect fish population. The survival of the fish is essential to the survival of the lamprey. The lampreys’ need a food source to survive. The same abiotic factors can also affect the microscopic organisms that the lamprey larva feed on. If said abiotic factors decrease the populations of microscopic organisms, the larva will have nothing to feed on, meaning the larva will not survive to become full grown lampreys.
