how many hundreds in a million
Answer: Ten lakhs make a million. How big is a bajillio...
Autotrophs act as producers and are critical for all ecosystems. Without these organisms, energy would not be available to other living organisms and life itself would not be possible.
Autotrophs get their food by producing it themselves. Most autotrophs use sunlight to convert water and carbon dioxide into glucose in a process called photosynthesis. It should be noted that a few autotrophs use a different process called chemosynthesis to produce glucose through oxidation in the absence of sunlight.
Energy from the sun flows to all life on Earth through the food chain with the help of autotrophs. … Without autotrophs, heterotrophs cannot survive. So autotrophs aren’t only producers because they make food for themselves, but also because they make the energy that all other living things depend on.
What would happen if all autotrophs died leaving only heterotrophic organisms? All life would be unable to survive. … Without them, heterotrophs cannot convert simple, inorganic substances into the nutrients they need.
The other dependent animals or trophic level will not survive without food. Without plants and animals decomposers will die and there will be no life on earth. So, if there were no producers, the food chain would not initiate and all the living species on earth would die.

It is incorrect as , autotrophs can convert carbon dioxide and water into carbohydrates only in the presence of sunlight. The autotrophs contain the green pigment clled chlorophyll which is capable of trapping sun energy.
Most plants are autotrophs because they make their own food by photosynthesis. … Some plants are non-photosynthetic and parasitic, obtaining their food through a host. All parasitic plants have special organs called haustoria that infiltrate into the host plant’s tissues and extract water and nutrients.
Fungi and other organisms that gain their biomass from oxidizing organic materials are called decomposers and are not primary producers.
Most autotrophs make their “food” through photosynthesis using the energy of the sun. Heterotrophs cannot make their own food, so they must eat or absorb it.
Only autotrophs can transform that ultimate, solar source into the chemical energy in food that powers life, as shown in Figure below. Photosynthetic autotrophs, which make food using the energy in sunlight, include (a) plants, (b) algae, and (c) certain bacteria.
Autotrophs obtain energy through producing their own energy by using chemicals in their environment or by photosynthesis, while heterotrophs obtain energy by consuming and converting that energy.
