Question

Saved Help Save & Exit Trophic interactions Food chains represent oversimplifications of producer-consumer relationships. Indicate if the following statements about interactions among trophic levels are true or false in explaining the complexity of these interactions. a Plants may be consumed by many different species, which in turn are the potential prey of many other different species. True b. Energy flows both from producers to consumers and from consumers to producers, which makes it difficult to depict relationships in a linear food chain False- c. Species can be in more than one trophic level (e.g, might be both a primary and secondary consumer) True d. While consumers get most of their energy by eating other organisms, most are also capable of producing their own food, blurring the line between producers and consumers. False e. Decomposers might feed on plant leaves or branches that have fallen to the ground. making them primary consumers, but they might also feed on animal carcasses, making them secondary consumers. True f Decomposers are thought to be at the base of complex food webs, whereas producers are depicted as the base of most food chains. (Click to select)

Explanation / Answer

F) TRUE,

The base or basal species in a food web are those species without prey and can include autotrophs or saprophyticdetritivores (i.e., the community of decomposers in soil, biofilms, and periphyton.

E) TRUE, DETRITOUS ARE BOTH PRIMARY AS WELLAS SECONDARY CONSUMERS.

D) FALSE, consumer never produce their own food.

c) TRUE. SPECIES CAN BE BOTH PRIMARY AS WELL AS SECONDARY CONSUMERS.

B) FALSE, Energy always flow undirectionally , ffrom producers to consumers.

A) TRUE.
