Heterotrophs are living things that can't make their own ___.

All organisms can be divided into two broad categories: heterotrophs and autotrophs. Heterotrophs are living organisms that cannot make their own food. They are dependent on other organisms for food and nutritional requirements. Human beings, animals, etc. are all heterotrophs. We obtain our food from plants (such as fruits and vegetables) and/or animals (chicken, fish, cows, etc.).

In comparison, autotrophs are organisms that make their own food. Examples of autotrophs include plants and algae. Autotrophs use...

All organisms can be divided into two broad categories: heterotrophs and autotrophs. Heterotrophs are living organisms that cannot make their own food. They are dependent on other organisms for food and nutritional requirements. Human beings, animals, etc. are all heterotrophs. We obtain our food from plants (such as fruits and vegetables) and/or animals (chicken, fish, cows, etc.).

In comparison, autotrophs are organisms that make their own food. Examples of autotrophs include plants and algae. Autotrophs use sunlight for the process of photosynthesis, which generates glucose as food. All other organisms depend on autotrophs for food and nutritional needs.

In an ecosystem, complex interactions take place between heterotrophs and autotrophs. Heterotrophs consume autotrophs. Heterotrophs also produce carbon dioxide as part of their respiration process, which is used by autotrophs in the process of photosynthesis.

Hope this helps.
