The relationship between the given terms.
Introduction : Organisms interact with each other in different ways within an ecosystem. They differ in how they derive their energy and so they are classified as autotrophs or heterotrophs based on how they obtain their food in an ecosystem.
Answer to Problem 14A
Heterotroph, omnivore and carnivore are living organisms that cannot prepare their own food.
Explanation of Solution
Heterotroph- It is a living organism that cannot prepare its own food but is dependent on other organisms for food. They rely on autotrophs and other heterotrophs for food. So, they are also called consumers. Examples are humans, lions, deer, etc.
Omnivore- It is a heterotroph that feeds on both plants and animals. Examples are humans, bears, mockingbird etc.
Carnivore- It is a heterotroph that preys on other heterotrophs such as lions, wolves and lynxes.
All these three categories of organisms cannot prepare their own food.
