Answer 1

Answer: (A), (B), (C)

The correct options are
A Living things require food.
B Living things exhibit growth.
C Living things perform respiration.

Living things require food to survive and grow. Food makes the body grow faster and gives energy to the body to help it perform the life activities.
All living things take in food to obtain energy. That energy is used for growth. Organisms increase in height, weight etc. to exhibit growth.
Living organisms have different stages of growth in their life.
Respiration is the process of breathing in oxygen and giving out carbon dioxide. Respiration takes place in every cell and is called as cellular respiration. Oxygen is necessary to break food and produce energy from it. Different animals possess different organs for respiration.
All living organisms move at some point or another. Even plants, which are stationary, exhibit movement in the form of roots growing towards the earth or the stems bending towards sunlight.
