Caterpillars of swallowtail butterflies feed on the leaves of citrus trees and
aphids feed on the young shoots of the same trees. Ladybirds eat the aphids.
i. Which organism is the producer in the above example?
Answers
Explanation:
A - In agriculture, the yield is a measurement of the amount of a crop grown, or product such as wool, meat or milk produced, per unit area of land. ... Increased crop yields also means fewer hands are needed on farm, freeing them for industry and commerce.
B - For nutrition, aphids usually feed on the plant's phloem sap, which is rich in sugars, minerals and other elements. The phloem is responsible for distributing this kind of sap throughout the plant. For water, aphids draw fluid from xylem, where raw sap runs directly from the roots.
The variety of organisms narrows at each level of the taxonomy, as indicated by the associated common names. Organisms are grouped at each level based on shared features. As the number of features they have in common increases, fewer organisms exist that share them all. This description of how closely related organisms are to one another is the central theme of taxonomy. Shared features that are useful for taxonomy are often physical traits, such as number of wings or legs; however, in some cases, behaviors can also be useful, as in the family Apidae, which consists hive-nesting or social bees.
