Looking at the image of the freshwater lake ecosystem in the reading, can you name biotic and abiotic factors in this specific ecosystem? What changes in this ecosystem would impact the biotic factors? A sample answer could include the following: Biotic: Fish Crayfish Zooplankton Grasses

Abiotic: Sun Sedimentation Weather Changes:

Water pollution Air pollution Overfishing Dredging of the bottom of the lake

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.

wait any answer choices plz

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
