Answer:
Biotic factors include: Fish (phytoplankton-eater, zooplankton-eater, predator)
, Crayfish
, Zooplankton
, Grasses, phytoplankton, herbivorous insect, worms, etc.
Abiotic factors include: Sunlight, Rainfall, Sedimentation, Weather, Minerals, Temperature.
Changes that would impact the biotic factors include:
Water, air pollution
Human activities: such as overfishing, rechanneling of the water for purposes such as irrigation, domestic or industrial use, or dredging of the bottom of the lake.
Explanation:
An ecosystem is composed of biotic and abiotic factors. Abiotic factors are non-living environmental factors such as water, air, soil, sunlight, and minerals. In aquatic ecosystems, abiotic factors include substrate type, water depth, nutrient levels, temperature, salinity, and waterflow. Biotic factors are the living organisms in the ecosystem and they include animals, birds, plants, fungi, etc.
In the image of the freshwater lake ecosystem given,
Biotic factors include: Fish (phytoplankton-eater, zooplankton-eater, predator)
, Crayfish
, Zooplankton
, Grasses, phytoplankton, herbivorous insect, worms.
Abiotic factors include: Sunlight, Rainfall, Sedimentation, Weather, Minerals, Temperature.
Changes that would impact the biotic factors include:
Pollution: pollution such as water pollution and air pollution will adversely impact the biotic factors.
Human activities: such as overfishing, rechanneling of the water for purposes such as irrigation, domestic or industrial use, or dredging of the bottom of the lake.
The eggs of the fluke are passed into water supplies from feces and urine of infected people. After hatching the parasite actively swims and invades the body of a snail, usually by penetrating through the snail's foot. The parasite requires the presence of certain species of snails (e.g., Oncomelania, Biomphalaria, Bulinus) to transform (and multiply) itself into an infective stage, called cercaria.
