Question

Energy is needed to carry out life processes. Energy is required to break down and build up molecules and to transport molecules across plasma membranes. All life’s work needs energy. A lot of energy is also simply lost to the environment as heat. The story of life is a story of energy flow — its capture, its change of form, its use for work, and its loss as heat. Energy, unlike matter, cannot be recycled, so organisms require a constant input of energy. Life runs on chemical energy. Where do living organisms get this chemical energy? The chemical energy that organisms need comes from food. Food consists of organic molecules that store energy in their chemical bonds. In terms of obtaining food for energy, there are two types of organisms: autotrophs and heterotrophs. Autotrophs are organisms that make their own food. Autotrophs are also called producers. They produce food not only for themselves but for all other living things as well .This is why autotrophs form the basis of food chains. Heterotrophs are living things that cannot make their own food. Instead, they get their food by consuming other organisms. Heterotrophs include all animals and fungi and many single-celled organisms. What do you think would happen to consumers if all producers were to vanish from Earth? Which of the statement below is incorrect? a) Inside every cell of all living things, energy is needed to carry out life processes b) The chemical energy that organisms need comes from food c) All Organisms do not need energy to do work

Answer 1

The incorrect statement is 'All Organisms do not need energy to do work' as all life requires energy for its processes. Energy comes from food which is created by producers (autotrophs) and consumed by others (heterotrophs). Without producers, life on Earth would be severely disrupted as they form the basis of food chains. Every organism, autotrophic or heterotrophic, needs energy to function.

Step-by-step explanation:

The statement 'All Organisms do not need energy to do work' is incorrect. Energy is fundamentally important for all life processes in both autotrophs and heterotrophs.

Explanation in 100 words: Every single organism on Earth requires energy to function. This can be obtained from food by heterotrophs or produced through photosynthesis by autotrophs. Energy is used by organisms for various life processes like growth, reproduction, and maintenance. When producers (autotrophs) provide the basis of food chains by making their own food, consumers (heterotrophs) depend on these producers for their energy needs. If all producers were to vanish, it would cause a major disruption in the food chain which would be detrimental to all life on Earth.

Conclusion: Energy is crucial for life. Without it, life as we know it would cease to be.
