Question

Which type of ocean sediment contains the remains of dead organisms?

Answer 1

The biogenous sediment contains the remains of dead organisms such as shells and skeletons.

Answer 2

Biogenous sediments are a kind of ocean sediments and ooze is one of the biogenic sediments which contains the remains of dead organism.

Explanation:

Ocean sediments are the insoluble materials like rocks or other solid particles which enter the ocean from the land area because of wind blow, floods, ice break and river water mixing etc.

Sediments do not have a definite shape and size. They may agglomerate at various temperatures and they are originate or coagulate at any locations of ocean.

The ocean sediments are classified in four types based on the basic composition of sediments.

They are lithogenous sediments which is composed of rocks or other solid land wastage, biogenous sediments which are composed of remains of dead organisms and their skeletons, hydrogenous sediments which are composed of the chemical wastage released in water from different factories and cosmogenous sediments which are composed of any waste entered in ocean from space like asteroid remains, rocket remains etc.

Among these, the ocean sediment which contains remains of dead organisms are termed as biogenous wastage.

The best example of biogenic sediments composed of dead organism remains are termed as ooze which is composed of 30% biogenic remains of plankton and its skeleton.
