This Life Processes Class 10 MCQ Online Test covers various topics such as nutrition, transportation, metabolism, respiration, reproduction, and excretion, which help in the maintenance of living organisms.
Life processes are the functions performed by living organisms, such as an animal or plants, to maintain life. They are part of the intactness of living beings; they act between the ingestion of food and excretion, transportation of substances through some medium, growth of cells and tissues, homeostasis (staying the same despite changes in the organism), reproduction, and responses to stimulus. The physiological activities required to sustain life are known as life processes (or biological processes).
Life Processes Class 10 MCQ Online Test is the most important segment of your preparation. You must have to perform well in your upcoming exam. So, we made this Online quiz to test your knowledge about Life Processes.

FAQ on Life Processes Class 10 MCQ Online Test
Why is diffusion insufficient to meet the oxygen requirements of multicellular organisms like humans?
Answer: In multicellular organisms like humans, all the body cells are not in direct contact with the surrounding environment. Therefore, every cell of the body will not get oxygen as per need by the process of diffusion from the environment. Therefore diffusion is insufficient to meet the oxygen requirements of multicellular organisms.
What criteria do we use to decide whether something is alive?
Answer: The main criteria used to decide whether something is alive are breathing and respiration. However, living beings also show growth and movement.
What are outside raw materials used by an organism?
Answer: Any organism uses organic molecules as raw material. Heterotrophs use food and autotrophs use carbon dioxide, minerals, water, and all organisms use oxygen (for respiration) as raw materials.
What is the function of digestive enzymes?
Answer: The food we eat is complex in nature, i.e., it contains complex molecules. Digestive enzymes break down these complex molecules into smaller simpler molecules so that they can be absorbed by the walls of the intestine.

EXPLAIN THIS QUESTION Single circulation, i.e., blood flows through the heart only once during one cycle of passage through the body, is exhibited by which of the following:
Blood flows through the heart only once during one cycle of passage through the body, this is called single circulation which is exhibited by Hippocampus, Exocoetus and Anabas. Here the blood flows only once through the heart during one cycle of passage through the body. It occurs in fishes. This is less efficient as gill capillaries slow down the blood flow, hence the body receives blood at a low pressure which decreases the rate of oxygen supply to the cells.
