Answer:
The correct answer is E) eutely
Explanation:
Nematodes are organisms with bilateral symmetry, although their organs are coiled, sometimes one of the limbs is lost and many of sedentary life tend to radial symmetry. One of the most striking characteristics of these animals is that their growth is not produced by an increase in the number of cells that compose them, but by an increase in the size of the already existing cells; in fact, in most adult tissues the number of cells is constant, a phenomenon known as eutelia.
Eutelia is the condition of an organism composed of a constant number of cells or syncytial nuclei in all adult individuals of a species, such as nematodes, it means that body growth is not carried out by increasing the number of cells but by the growth of existing cells.
Ans.
The given diagram represents a cladogram, which is used to show evolutionary relationships between various organisms or species.
The intersection points between the lines show the common ancestors, which evolved into different organisms at the end of the branches, as A, B, C, D.
The first branch end (A) represents that most primitive organism, while the last branch end (D) represents the most recent organism.
Thus, the correct answer is option). 'organism A is the most primitive organism.'
A rabbit is a consumer because it gets its energy from eating other living organisms. A fungus is a decomposer because it gets its energy from breaking down the material of dead organisms or their products.
