What is the best explanation for the difference in food intake needed for endotherms and ectotherms?

Endotherms require a higher metabolic rate than ectotherms. This is because endotherms maintain a regular/ constant body temperature while ectotherms depend on the heat in the environment to regulate body temperature. Therefore, endotherms must eat regularly to maintain this metabolic rate and sustain constant temperatures.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
