Hi Apoorva,
All animals are heterotrophs. They depend on plants or other animals for their food.
There are basically two types of nutrition-Autotrophic nutrition and heterotrophic nutrition.
 Autotrophic nutrition - The mode of nutrition in which organisms (plants) make their own food using sunlight, water, and carbon dioxide is known as autotrophic nutrition.
Heterotrophic nutrition- The mode of nutrition in which organisms consume food, cannot manufacture their own food is known as heterotrophic nutrition. Animals and some plants are heterotrophic organisms. They are dependent on plants and other animals for nutrition.
 
Heterotrophic nutrition is further divided into sub categories- Parasitic nutrition, Symbiotic  nutrition and saprophytic nutrition.
 Parasitic nutrition - The mode of nutrition in which organisms derive nutrition from body of another living organism is known as parasitic nutrition. For example- Cuscuta is a plant that cannot manufacture its own food as it lacks chlorophyll, so derive nutrients from other plants.
Saprotrophic nutrition- The mode of nutrition in which organisms derive nutrition from dead and decaying plants and animals. For example- Mushroom (fungus) feed upon dead and decaying plants and animals.
Symbiotic nutrition – The mode of nutrition in which organisms live in association with other plants or animals and share their resources. In this kind of relationship, both the partners are benefitted by the relationship. For example- Lichen (association between plants and animals)
 
Snail –Their mode of nutrition is heterotrophic. They eat vegetation, flesh and some chalk also.
 Ant – Their mode of nutrition is heterotrophic. They eat sugar and other sweet products.
 Eagle -Their mode of nutrition is heterotrophic.  They eat other animals such as rats, rabbits and some dead animals.
 Humming- Their mode of nutrition is symbiotic. They suck nectars from flower.
 Lice – Their mode of nutrition is parasitic. They suck blood from human body
 Mosquito -Their mode of nutrition is heterotrophic. They suck blood from human body and nectars from flowers also.
 Butterfly - Their mode of nutrition is symbiotic. They suck nectars from flower.
 Housefly - Their mode of nutrition is heterotrophic. They eat anything left over by other animals and human beings.
 
Hope this answer helps,
All the best!
