Question

The amount of planktons to be found in the ocean is determined by 1. Depth of the water. 2. Ocean currents. 3. Temperature and Salinity. 4. Length of day and night. a) 1 and 2 are correct b) 1,2 and 3 are correct c) 1,3 and 4 are correct d) All are correct.

Answer 1

Answer: C is the answer.

Explanation:

Because most phytoplankton live in the upper 100 metres of the ocean, as they rely on sunlight to photosynthesise.

While zooplankton can live in any depths as the prey upon phytoplanktons.

Whereas bacterioplankton is autotophic and produce their own food through photosynthesis .

I hope this answer is helpful to you.

Thank you!!

Answer 2

Answer:

All the avove

Explanation:

Autotrops(phytoplankton) need light (depth and temp dependent)

Can't survive extreme temperatures

Ocean currents alter the surface temperature

So all the above factors impact planton
