Question

Plants can make their food. They are called
(a)Autotrophs
(b)Heterotrophs
(c)Parasites
(d)None of the above

Answer 1

Hint: Plants are photosynthetic eukaryotic organisms which include all living things that are not animals and all algae are treated as plants. They get energy from the sunlight by the process of photosynthesis and contain chlorophyll A and B that gives them their green color.

Complete answer:
Plants can make their food. They are known as autotrophs. Organisms that produce organic compounds like carbon dioxide from simple substances and use energy from sunlight. They do not need a living source and are the producers in a food chain like that of algae in water and plants on land. They help in reducing carbon dioxide to make organic compounds for the biosynthesis of organic compounds and stored them as chemical fuels. They make their food by the process of photosynthesis in the presence of sunlight. They convert electromagnetic energy from sunlight into chemical energy in the form of glucose including methanogens which are chemotrophs that use organic or inorganic chemical compounds as their source of energy.

Additional information:
Heterotrophs: Heterotrophs are the organism which cannot prepare their food. They derive nutrition from other sources that mainly plant or animal matter. They are the primary, secondary and tertiary consumers in the food chain. Heterotrophs constitute organography and lithotrophs. Carbon compounds such as carbohydrates, proteins, and fats from plants and animals are reduced by the organography and lethal heterotrophs use inorganic compounds to obtain electrons such as ammonium, sulfur, or nitrite.
Parasites: The species that show parasitism in which the organism lives on or inside another organism as the host and cause it some harm which is adapted structurally to the way of life. It includes protozoans such as the agents of malaria and sleeping sickness. Lice and mosquitoes are some of the hookworms that constitute parasites. Parasites reduce the fitness of the host by exploiting the resources which are necessary for its survival and feed on them by using an intermediate host for their transmission from one host to another.

So, the correct answer is 'autotrophs'.
