Summary Introduction

To classify:

Organisms as heterotrophs or autotrophs.

Introduction:

The organisms that make their food by their own are known as autotrophs. They are also known as producers as they produce their own food. The organisms who do not make their food by own self is known as heterotrophs. They are known as consumers as they take their food from plants and other resources.

Explanation of Solution

Organism	Symbol	Autotroph/Heterotroph
Alligator	H	Heterotroph
Squirrel	H	Heterotroph
Maple tree	A	Autotroph
Whale	H	Heterotroph
Moss	A	Autotroph
Siberian tiger	H	Heterotroph
Daffodil	A	Autotroph
Rhinoceros	H	Heterotroph
Dandelion	A	Autotroph
Rabbit	H	Heterotroph
Tomato	A	Autotroph
Cockroach	H	Heterotroph

Maple tree, Moss, Daffodil and Dandelion are plants and they can prepare their own food that’s why they are autotrophs.

Alligator, squirrel, whale, Siberian tiger, rhinoceros, rabbit and cockroach cannot prepare their food by own and depend on plants and other living organisms. That’s why they are heterotrophs.
