Which energy transfer is least likely to be found in nature ? A- consumer to consumer
B- producer to consumer
C-host to parasite
D- predator to prey

Answers

The energy transfer that is least likely to be found in nature is predator - prey. Details about energy transfer can be found below.

How is energy transferred in nature?

Energy is transferred in nature when organisms feed on one another.

For example;

  • Producers, which are the initiator of the energy transfer are fed upon by consumers

  • Consumers like herbivores are also fed on by other consumers like carnivores

  • Parasitic organisms feed and derive nourishment from their host

However, the transfer of energy does not occur in the direction of a predator to prey but occurs the other way around.

_____ converts atmospheric nitrogen into ammonium, which plants absorb. The plants, by _____, incorporate the ammonium into proteins. Ammonification, nitrification;Nitrogen fixation, assimilation;Assimilation, nitrogen fixation; or Nitrification, denitrification?which one?

Answers

The answer is Nitrogen fixation, assimilation.

Plants are not able to directly use atmospheric nitrogen. It must be converted into different form through a nitrogen cycle. In the process of nitrogen fixation, nitrogen fixing bacteria converts atmospheric nitrogen into ammonium. In the process of assimilation, plants incorporate ammonium into proteins.
The next steps are ammonification, conversion of organic nitrogen from dead plants back to ammonium; nitrification, conversion of ammonium to nitrates; and denitrification, conversion of nitrates into atmospheric nitrogen.

Answer:

The answer is Nitrogen fixation, assimilation.

What is different about synthesis of lagging strand compared to synthesis of the leading strand? A) synthesis of leading strand does not occur in 5* to 3* direction. B) Synthesis of lagging strand does not use DNA polymerase C) Synthesis of lagging strand does not use base pairing D) Synthesis of the leading strand does not involve RNA primers and Okazaki fragments

Answers

The difference in synthesis of lagging strand compared to synthesis of the leading strand is D) Synthesis of the leading strand does not involve RNA primers and Okazaki fragments. DNA polymerase adds nucleotides at the 3' end toward the 5' end in the direction 3' to 5'. The free end of the lagging strand is 5' so DNA polymerase cannot start from that end. The replication of the lagging strands is discontinuous and it involves RNA primers and Okazaki fragments. Synthesis of the leading strand is under control of DNA polymerase.

d) synthesis of the leading strand does not involve RNA primers and Okazaki fragments
