Food provides molecules that serve as fuel and building material for all organisms. plants undergo photosynthesis and make their own food. other organisms, like us and the horse seen above, are consumers and eat food. how do all organisms use food as fuel? be sure to include the name of the process in your answer. me.

Ans.

All living organisms, including plants and animals get fuel by the process of respiration. It involves chemical breakdown of complex food molecules (such as sugars)  in the presence of oxygen and release energy in the form of ATP molecule, along with water and carbon dioxide.  

The ATP formed during respiration releases energy during its hydrolysis and acts as energy source for all cellular processes.

The trophic level of an organism in a food web represents the position such organism occupy in the food web.

Within the food web, energy is transferred from producers to consumers and finally to decomposers.

Option A is incorrect because fungi (a decomposer) cannot start a food web. Option B is incorrect because plant is a producer and as such, cannot end a food web. Option D is incorrect because algae (a producer) cannot be at the middle.

The correct option is C. Algae is a producer, fish is a primary consumer and feeds on algae, grizzly bear is a secondary consumer and feeds on fishes while fungi is a decomposer and decomposes the grizzly bear when it dies.
