Question

How do living things get their food

Answer 1

ANSWER:-

• The general requirement for energy and materials is common in all organisms, but it is fulfilled in different ways.
• Some organisms use simple food material obtained from inorganic sources in the form of carbon dioxide and water.
• These organisms, the autotrophs include green plants and some bacteria.
• Other organisms utilise complex substances.
• These complex substances have to be broken down into simpler ones before they can be used for the upkeep and growth of the body.
• To achieve this, organisms use bio-catalysts called enzymes. Thus, the heterotrophs survival depends directly on autotrophs.
• Heterotrophic organisms include animals and fungi
