A low percentage of energy is transferred at each trophic level because some of the organism is not consumed, some is undigested (lost in feces), some is lost in excretory products (urine), and some is lost as heat from respiration.
Un procentaj mic de energie este transferat la fiecare nivel trofic deoarece o parte a organismului nu este consumată, alta nu este digerată (pierdută în fecale), o parte se pierde în produsele de excreție (urină), iar o parte se pierde sub formă de căldură din respirație.
| Front | Why is a low percentage of energy transferred at each stage? |
|---|---|
| Back | some of the organism is not consumed some parts are consumer but cannot be digested therefore they are lost in faeces some energy lost in excretory materials (urine) some energy losses occur as heat from respiration and lost to environment |
