Nutritin important for a living organisms
Answers
Explanation:
Nutrients are chemical substances found in every living thing on Earth. They are necessary to the lives of people, plants, animals, and all other organisms. Nutrients help break down food to give organisms energy. ... The human body can also synthesize some nutrients, such as amino acids.
Answer:
Nutrition is the essential organic nutrients living organisms require for growth, maintenance, reproduction and repair. This is an essential process for the organism’s survival. Living organisms require energy to survive; this energy is derived from nutrients, or food. Ingestion, digestion, absorption and excretion are the stages of processing food. Heterotrophs are organisms which cannot synthesise their own food and are therefore totally reliant on organic substances for nutrition. Animals are heterotrophs and are divided into three categories; herbivores, carnivores and omnivores depending on how they obtain their food. Herbivores: eat mainly plant material, seeds or fruit. (Gordon McL Dryden, 2008). Omnivores: eat both vegetable and animal material. Carnivores: eat meat (they can also eat insects and fish).Plants are autotrophs, they synthesise organic substances from inorganic molecule using sunlight energy.
