Define disphotic zone?

Chemistry
2 answers:
Llana [10]3 years ago

Explanation:

The photic zone, euphotic zone, epipelagic zone, or sunlit zone is the uppermost layer of a body of water that receives sunlight, allowing phytoplankton to perform photosynthesis. It undergoes a series of physical, chemical, and biological processes that supply nutrients into the upper water column. The photic zone is home to the majority of aquatic life due to its location.

Photosynthesis in photic zone Edit

In the photic zone, the photosynthesis rate exceeds the respiration rate. This is due to the abundant solar energy which is used as an energy source for photosynthesis by primary producers such as phytoplankton. These phytoplankton grow extremely quickly because of sunlight's heavy influence, enabling it to be produced at a fast rate. In fact, ninety five percent of photosynthesis in the ocean occurs in the photic zone. Therefore, if we go deeper, beyond the photic zone, such as into the compensation point, there is little to no phytoplankton, because of insufficient sunlight.[1] The zone which extends from the base of the euphotic zone to about 200 meters is sometimes called the dysphotic zone.[2]

follow me ok nice study ☺️☺️☺️

Answer:

The disphotic zone also known as the twilight zone :- is the layer of water with enough for the rate of photosynthesis to be greater than the rate of respiration.

-The depth at which less than one percent of sunlight reaches begins the aphotic zone

A jogger runs a mile in 8.92 minutes. 1 mi=1609m; calculate her speed in km/hr
olchik [2.2K]

Answer:

Speed = 3.30 \frac{km}{hr}

Explanation:

Given

Distance = 1 mile

Time = 8.92 minutes

Required

Calculate Speed in km/hr

Speed is calculated as thus;

Speed = \frac{Distance}{Time}

Substitute 1 mile for distance and 8.92 minutes for time

Speed = \frac{1\ mile}{8.92\ minutes}

Convert Miles to Kilometres

If

1\ mile = 1609\ m;

Then

1\ mile = \frac{1609\ km}{1000}

1\ mile = 1.609\ km --- (1)

Convert minutes to hour

1\ minutes = 0.0167\ hour

Multiply both sides by 8.92

8.92 * 1\ minutes = 0.0167\ hour * 8.92

8.92 \ minutes = 0.148964\ hour ---- (2)

By substituting (1) and (2) in Speed = \frac{1\ mile}{8.92\ minutes}, we have

Speed = \frac{1.609\ km}{0.48694\ hour}

Speed = 3.304309 \frac{km}{hr}

Speed = 3.30 \frac{km}{hr} -- Approximated
