FAQs

Life processes such as nutrition, respiration, transportation, and excretion ensure that organisms maintain homeostasis, grow, and reproduce. Without these processes, organisms would not be able to survive.

Double circulation ensures that oxygen-rich blood is separated from oxygen-poor blood, improving the efficiency of oxygen delivery to body tissues.

While photosynthesis produces glucose (food), respiration breaks down glucose to release energy for cellular activities. Both processes are necessary for survival.

Enzymes catalyze the breakdown of large food molecules into smaller, absorbable molecules. For example, amylase breaks down starch into maltose.
