Lamprey's Biome


 * Biome:** Marines, both salt and freshwater.

**Abiotic Factors:** Wind Underwater caves Sand Temperature Pressure Sunlight Current strength and direction Concentration of salt Concentration of other minerals (C02, O2, ) pH Rocks

**Biotic Factors :** Other Fish Other Animals Bacteria Seaweeds and other aquatic plants Plants Coral reefs

If there is too much wind, there could be decrease the temperature in the air as well as the water while simultaneously decreasing the body temperature of the other fish as well as creating an environment not suited for the plant life. Ultimately decreasing food supply to the other fish, potentially harming the population. If the fish count is down, then it will leave less food for the Lamprey to prey on and impact their population in those areas. Increasing currents could cause certain fish, including the Lamprey could get carried to areas of the ocean where they do not belong and with the vast amount of eggs they produce it could cause the lamprey population to spread to areas that they should not be, and upset the ecosystem. Decreasing currents could cause the fish to come closer to shore where they are not adapted or suited to live and impact the population size. If the pH is off than the water could become cloudy, which blocks the length the sunlight can go. If the sun cannot go far distances it cannot reach the plants and they cannot survive. If the sunlight decreases water temperature as well, the coral reefs cannot begin to grow. If certain waters lack coral reefs than the fish cannot hide and will become prey more easily; if too much coral reef grows, than this could cause overpopulation because the fish could be too hard to find for their predators. Everything relies upon one another and is a balanced system. If that balanced system is broken in just one part, it disrupts the whole ecosystem.
