Answer:B. Sunlight provides energy to producers
Explanation: photoautotrophs (plants) produce energy from sunlight by photosynthesis. This is the only energy production based on an external source of energy. Plants, whether alive or dead, are consumed by heterotrophs - bacteria, fungi and animals. The nutrients and energy from dead heterotrophs (and some live ones) are recycled by both autotrophs and heterotrophs.
Answer: High Frequency waves by method of compression bone conduction
Explanation: in this, vibration of the bones of the skull and sometimes, arguably soft tissues leads to the production of sounds. The outer and middle ear is bypassed in this method of sound production. Sound reaches the inner ear directly and its a process largely involved in designing hearing aids.
Answer:
The term which can be used for this species is psychrophile. Psychrophilic bacteria are the bacteria which love to grow at low temperature. The optimum they like to grow is 15°c and the highest temperature they grow is 20°c.
The minimal temperature a psychrophile grows is zero degree Celsius so a psychrophile can grow easily at refrigeration temperature which is 4°c. Phychrotrops are bacteria which can grow at cold temperature but tends to grow well above 15-20°c.
Therefore according to this question, there was no growth at 37°C and 50°C, very slight growth out on the benchtop, and abundant growth at refrigeration which determine that the species is a psychrophile.
