What would happen to ecosystems without producers in the food chain A.Without producers, there would be no food for consumers and decomposers. The food chain would collapse. B.Without producers, the food chain would only include plants such as trees and shrubs. The food chain would not contain consumers or decomposers. C.Without producers, only aquatic ecosystems and their food chains would exist. D.Without producers, only consumers and decomposers of ecosystems would survive in the food chain.

Answer:

c

Explanation:

If there are no producers in the food chain, then there would be no food for the consumers and decomposers and the food chain will collapse. Thus, the correct option will be A.

A food chain can be defined as a linear network of links in a food web with the starting organism from the producers and ending at an apex with the predator species, detritivores, or the decomposer species.

Plants can make their own food through the process called as photosynthesis. Using the energy from the solar radiation (sun), water and carbon dioxide from the atmosphere and other nutrients, they chemically synthesize their own food. Since, they can make or produce their own food they are known as the producers.

Therefore, the correct option will be A.

Viroids’ largest impact is on ________.

The following case study is a paraphrase from "Good Clinical Practice. Standard Operating Procedures for Clinical Researchers" (Kolman, J., Meng, P. and Scott, G. editors; John Wiley and Sons publishers, 1998):

“While a study subject and a relative were walking in town one day during the summer, a hanging flower basket fell on a study subjects head, resulting in the study subject falling down and becoming unconscious. The subject’s relative called for an ambulance. On arrival at a local hospital’s Emergency Department, in which the subject regained consciousness but could not recall the event, a x-ray revealed a fractured skull. The subject’s consciousness level at this point was deteriorating and after further tests a subdural hematoma was diagnosed, which was evacuated under general anesthesia. Postoperative recovery was uneventful and progressing well until day four, when the patient developed acute dyspnea (shortness of breath) at rest during visiting time. An emergency lung scan was performed that confirmed a diagnosis of pulmonary embolism. The study subject was anticoagulated and was eventually discharged from the hospital”

Which of the following best describes why the two organisms you chose are closely related to each other using evidence from the chart?

Assume that gene A controls the conversion of a white pigment, P0 into another white pigment, P1 the dominant allele A specifies an enzyme necessary for this conversion, and the recessive allele a specifies a defective enzyme without biochemical function. Gene B controls the conversion of the white pigment, P1 into a pink pigment, P2 the dominant allele, B, produces the enzyme necessary for this conversion, and the recessive allele, b, produces a defective enzyme. The dominant allele, C, of the third gene specifies an enzyme that converts the pink pigment, P2 into a red pigment, P3 its recessive allele, c, produces an altered enzyme that cannot carry out this conversion. The dominant allele, D, of a fourth gene produces a polypeptide that completely inhibits the function of enzyme C; that is, it blocks the reaction P2-P3 Its recessive allele, d, produces a defective polypeptide that does not block this reaction. Assume that flower color is determined solely by these four genes and that they assort independently. In the F2 of a cross between plants of the genotype AA bb CC DD and plants of the genotype aa BB cc dd, what proportion of the plants will have (a) red flowers? (b) pink flowers? (c) white flowers?
