atroni [7]

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.

A Bunsen burner is used for heating in a laboratory. Which safety procedure is important to follow when using a Bunsen burner?
slavikrds [6]
Do not point the bunsen burner to the sides unless told so, wear safety goggles and a lab apron because the chemicals can spew out when it gets too hot, hold the bunsen burner on the bottom and never at the top, and keep it away from anything unless the lab instructor tells you to heat something up.

In which of the following situations does the cell use active transport?
ahrayia [7]

Answer:

The correct option is B. Sodium ions move into the cell from areas of lower

concentrations.

Explanation:

Active transport can be described as a process in which molecules move from an area of lower concentration to an area of higher concentration against the concentration gradient. Energy is required for the process of active transport to occur.

In the option B, sodium ions are moving into the cell from areas which have a low concentration of sodium i.e against the concentration gradient. Hence, option B tells that the sodium ions will move inside the cell by the process of active transport.
