Coccolithophores are phytoplankton, meaning that they are autotrophic. This in turn means that they are able to produce their own food using sunlight and nutrients from the deep waters.

What are three examples of nanoplankton?

Examples of nanoplankton include diatoms, dinoflagellates, and coccolithophores. These are small photosynthetic organisms that form an important part of the marine food chain.


What are 3 places carbon is stored?

Coal and oil are one useful form of fossil carbon. Another is limestone. Chalk deposits are also formed by calcium carbonate concretions of marine calcareous coccolithophores.


What material is chalk made of?

Chalk is primarily composed of calcium carbonate, a soft, white, porous sedimentary rock. It is typically formed from the shells of microscopic organisms called coccolithophores that have accumulated and solidified over millions of years.


What rock i s crumbly and contains fossils?

Chalk - however, the fossils are microfossils called Coccolithophores. Limestone is a soft sedimentary rock, not exactly "crumbly" like chalk but more likely to contain fossils visible to the naked eye.


Why is chalk found in bands?

In Geology the term 'Chalk' refers to a soft, white, porous, limestone, sedimentary rock composed mainly of the mineral calcite. It forms under relatively deep, quiet marine conditions from the gradual accumulation of minute calcite plates shed from planktonic microorganisms called coccolithophores. It is common to find flint and chert nodules embedded in chalk because some of these coccolithophores also have siliceous exoskeletons. The chalk in relatively thick layers deposited parallel to the earths surface and therefore appears in bands when exposed in outcrop. (In this respect it is little different form other sedimentary rock deposits).


What is calcareous ooze an example of?

Calcareous ooze is an example of a type of biogenic sediment made up of the skeletal remains of marine organisms like foraminifera, coccolithophores, and pteropods. It is a common component of deep-sea sediments in regions where these organisms are abundant.


What are the types of biogenenous sediments?

The types of biogenous sediments include calcareous ooze, siliceous ooze, and radiolarian ooze. Calcareous oozes are composed mainly of calcium carbonate from organisms like foraminifera and coccolithophores, while siliceous oozes are made up of silica-based remains from diatoms and radiolarians.


What are the two types of biogenous sediments?

The two types of biogenous sediments are siliceous oozes, which are made up of silica-based remains of diatoms and radiolarians, and calcareous oozes, which consist of calcium carbonate shells of organisms like foraminifera and coccolithophores.


What group of organisms provides skeletal remains for chalk deposition?

Marine organisms known as coccolithophores, which are single-celled algae with calcium carbonate plates, provide skeletal remains for chalk deposition. These organisms play a key role in the formation of chalk rocks through their accumulation of calcium carbonate plates in marine environments.
