Explanation:
In a food chain, only 10% of energy is transferred from one trophic level to another trophic level. If the energy produced at the producer level is 1000 J, then the energy available at the primary consumer level will be 100 J and energy available at the secondary consumer level will be 10 J.

Answer:
<u><em>The correct option is C) Prions</em></u>
Explanation:
Bovine spongiform encephalopathy (BSE) or Mad Cow Disease is a disease which occurs due to transmissible particles known as prions. Prions cannot be considered as living organisms as they do not acquire many of the living characteristics. They are just considered as a protein which gest converted into an activated, toxic form as soon as they encounter a host cell. This toxic protein harms the central nervous system (CNS) of the cow host and is transmissible.
Answer:
B. oxygen and carbon dioxide.
Explanation:
During cellular respiration, organisms uses oxygen for breakdown of food molecules such glucose and carbondioxide gas is released in the atmosphere. Respiration is a process in which energy is produced in the form of Adenine tri phosphate (ATP) and releases carbondioxide by the chemical combination of glucose and oxygen molecules. The type of respiration in which oxygen is used is known as aerobic respiration.
