Answer:
D
Explanation:
It is decomposed by decomposers and brought back into the food chain later. Decomposers like bacteria and fungi break down any amount of living and non-living organic matter that is left unconsumed in the ecosystem.
B. Bio genous Sediment
C. Hydrogenous sediment
D. Both A and B
The correct answer is option B, Bio genous Sediment
Reason -
The calcareous ooze is known as biogenous sediment as it has formed from the calcareous microscopic shells of the living organism. These oozes have primarily developed due to the deposition of soft muds in the ocean floor made up of calcium or diatoms or radiolarians.. These biogenous sediments are found in the form of a) mineral calcite and b) aragonite.
Calcareous ooze is an example of bio genous sediment and the correct option is option B.
Bio genous sediments are formed from the remains of marine organisms such as shells, skeletons, and other calcareous or siliceous materials.
Calcareous ooze specifically refers to sediment composed mainly of the calcium carbonate shells or tests of microscopic marine organisms like foraminifera and coccolithophores.
These organisms extract calcium carbonate from the water to build their protective structures, and when they die, their remains settle to the ocean floor, accumulating over time to form calcareous ooze. It is important to note that terrigenous sediments, which originate from land sources, can also mix with bio genous sediments in some areas, creating a combination of both types of sediment.
Thus, the ideal selection is option B.

Earth began warming out of the ice age 18,000 years ago.
b.
Glaciers stopped advancing 15,000 years ago.
c.
Sea levels during the ice age were higher than today.
d.
Forests and grasslands became more common after the ice age.
Small aquatic organisms, such as coral, are the producers of the ocean.
F
b. Bread mold
c. Portobello mushroom
d. Slime mold
Slime molds are not fungi, but are protists. Morel mushrooms, Bread mold, and Portobello mushrooms, are all types of fungi, which have spore-producing structures.
Among the options provided, the one that is NOT a fungus is d. Slime mold. Slime molds, despite their misleading name, are actually not fungi. They belong to a group of organisms known as protists. On the other hand, Morel mushrooms, bread mold, and Portobello mushrooms are all types of fungi. Fungi are characterized by their spore-producing structures and are traditionally classified in the kingdom Fungi, while protists are usually unicellular organisms that do not fit into any other kingdom.
