No, a funnel-shaped depression of limestone dissolved by rain is called a sinkhole. A cave is a natural underground void or cavity that is typically larger and more complex in structure than a sinkhole.

While a funnel-shaped depression of limestone eroded by rainwater is called a limestone pavement or a doline, a cave is a naturally occurring underground void typically formed through chemical weathering and erosion processes such as the dissolution of limestone by acidic groundwater.
No, a funnel-shaped depression in limestone caused by dissolution from rainwater is typically called a "sinkhole," not a cave. Sinkholes form when the surface layer collapses into an underground void, while caves are larger, underground chambers formed through the continuous erosion of limestone by acidic water over time. Both are features of karst topography but refer to different geological formations.
The funnel-like depression on the pellicle is called a "funnel depression" or "funnel-shaped depression." In the context of certain organisms, this structure can serve various functions, such as aiding in feeding or locomotion. Its specific characteristics may vary depending on the species and its ecological adaptations.
The funnel-like depression on the pellicle of some cells is called a cytostome. It is an opening that allows the cell to take in nutrients or expel waste.
A funnel-shaped depression caused by water is known as a "sinkhole." Sinkholes occur when water erodes the underlying limestone or other soluble rock, creating a void that eventually collapses, forming a depression. They can vary in size and depth and are often triggered by heavy rainfall or groundwater drainage. Sinkholes are commonly found in karst landscapes, where the geology is prone to dissolution.
The funnel-like depression on the pellicle is called a "pore." In some contexts, particularly in the study of microorganisms or certain biological structures, this feature can also refer to a "pit" or "invagination." These structures can play roles in various functions, such as nutrient absorption or communication between cells.

A funnel cloud may be called a condensation funnel or simply a funnel.
The depression on the pellicle of some protozoa, where food is ingested, is called an oral groove. It helps facilitate the movement of food particles towards the mouth of the organism for ingestion and digestion.
