This approach assumes that the mode of life of the fossil species is similar to that of the living organism of the Same genus or morphology. This approach has several weaknesses, the major problem being the Foraminifera • Foraminifera are single-shelled belonging to Kingdom Protista, Phylum Protozoa, Class Sarcodina • The word is from Latin foramen = hole, ferre = to bear • They possess pseudopodia • They have both benthic and planktic mode of life • Reproduction is through schizogony = asexual reproduction and gamogony=sexual reproduction Members of the Class Foraminifera are among the most abundant and most useful protists in the marine realm. Foraminifers are characterized by a protective shell (commonly called a test), which can be membranous, agglutinated, or calcareous (Sen Gupta, 2002 ). Foraminifera thus form part of a key link in marine food chains, assimilating energy available from minute autotrophs and also retrieving energy available during the final stages of degradation of organic debris. In turn, they support a variety of larger organisms and thus contribute to the diversity and secondary productivity of ecosystems. kingdom animalia mode of nutrition is important information accompanied by photo and HD pictures sourced from all websites in the world.
Their shells are also referred to as tests because in some forms the protoplasm covers the exterior of the shell.

They have a shell (test) made of calcium carbonate or of sand grains cemented by mucus. The pseudopods poke Depending on their ecological niches, foraminifera feed on different resources and therefore use diverse feeding strategies, such as selective and non-selective deposit feeding, passive suspension Foraminifera are single-celled ameboid protists, order Foraminiferida, which occupy marine environments from the greatest depths of the ocean to the brackish-freshwater transition in coastal zones.

Forams. Phylum- foraminifera nutritional mode- heterotroph Foraminifera (/ f ə ˌ r æ m ə ˈ n ɪ f ə r ə /; Latin for "hole bearers"; informally called "forams") are single-celled organisms, members of a phylum or class of amoeboid protists characterized by streaming granular ectoplasm for catching food and other uses; and commonly an external shell (called a "test") of diverse forms and materials. Three modes of nutrition (parasitism, grazing, and suspension feeding) are employed by the bioeroding Cibicides refulgens (Alexander and Da, 1987). This species can take up a part of its nourishment from the mantle of its host (the scallop Adamussium col- becki) so it is the only bioeroding foraminifera, inves- tigated to date, which can be Terms such as planispiral-to-biserial and biserial-to-uniserial are used when the mode of chamber addition changes during growth. Of the various kinds of wall composition and microstructure found in foraminifera, three basic types are common among living species. Foraminifera occupy different trophic levels and fill key trophic positions in benthic food webs, but detailed studies on their nutrition spectrum in inter- to supratidal environments are lacking.

This approach assumes that the mode of life of the fossil species is similar to that of the living organism of the Same genus or morphology.

R-mode analysis Planktonic foraminifera Factor analysis yielded a five-factor solution, since (a) this number of factors accounted for the 74.6% of the total variance (Table 3), (b) all the variables have a high communality (0.612-0.889) (Table 4) and (c) 5 factors remained after the
Micropaleontology –Science of Microfossils • Microfossils are the tiny remains of bacteria, protists, fungi, animals, and plants • A fossil group with at least two third of its population is visible under the microscope is a microfossil • These are a heterogeneous group of fossil remains studied as a single discipline.
