Generally, the quantity of rainfall in Nigeria and worldwide determines to a large extent the type of vegetation of each biome or habitat.

The correct option is D.

The mitochondria are double-membrane envelopes. The region between the outer and inner membranes, which is filled with liquid, is known as the outer compartment. The inner membrane has numerous folds called cristae.
Cristae are the sites of ATP synthesis, and their folded structure greatly increases the surface area where ATP synthesis occurs.
Transport proteins, molecules called electron transport chains, and enzymes that synthesize ATP are among the molecules embedded in the cristae. The cristue enclose a liquid-filled region known as the inner compartment, or matrix, which contains a large number of enzymes that are used in the process of acrobic respiration for classification in animals especially lower animal and not used for classification in plants.
Fucoxanthin is merely a type of pigment not a means of classification or grouping of piants
The correct option is D

Biotic component is the living component of the ecosystem. They involve plants and animals of a community which interact by feeding upon one another and competing for the available supply of such things as water and light as a result, biotic component of an ecosystem can be called organisms.
The correct option is B

Seedless plants include bryophyles, (mosses & liverwort), pteridophytes (e.g. fern plant), thallophyles (c.g. red, brown & green algac).
Gymnosperms bear seed which is naked and are only borne on special compartment called cones (e.g. conifers).
Fungi is not a plant; it belongs to a separate kingdom. Bacteria are not classified as a plant as they also belong to a separate kingdom (moncran).
The correct option is D
