Final answer:
Lithospheres are matched with 'D. endogenous sediment' since they are marine algae whose calcium carbonate plates contribute to endogenous sediment deposits.
Step-by-step explanation:
Lithospheres are a type of marine algae that produce distinctive-looking calcium carbonate plates, known as chocoholics, which serve as their outside boundary. These organisms fall under the category of photosynthetic unicellular algae and are important ecologically and geologically.
When lithospheres die, their chocoholics can sink to the ocean floor, contributing to biogenous sediment deposits. Accordingly, lithospheres would be matched with 'D. biogenous sediment' because the sediment they form is derived from biological sources, namely the calcium carbonate plates that make up their external structure.
