Question

The lizard eats the small insects and worms. This type of eating habitat is known as-
A) Omnivore
B) Carnivore
C) Herbivore
D) None of these

Answer 1

Hint: Eating habits of animals are different. AS we know that different animals have different eating habits. It helps in better adaptation as well as maintaining the ecosystem. Animals like cows, sheep, goats eat grass so they come under herbivores. They depend on plants to survive.
Similarly, other animals like lion, tiger fox feed on other animals comparingly smaller to them in size. They are not dependent on plants for food.
This cycle of feeding on plants or animals on animals is called the food chain.

Complete answer:
Option A) Omnivore: Omnivore as we know are the animals which feed on both plant products as well as animals, which are smaller to them in size. Example – pigs, dogs, bears Hedgehogs, squirrels etc.
They feed on a variety of materials like plants, animals, fungi and tiny insects.
Human beings are also omnivores as they also feed in both vegetables and meat.
They come under special niches in terms of food behavior and feeding habits.
So, option A is not correct.
Option B) Carnivore: Carnivore means meat eater so animals which feed or obtain their nutrition or meet their requirements solely on animal flesh for survival are called carnivore animals.
There can be two types of carnivores – facultative carnivore and obligate carnivore.
Facultative carnivores are animals which also consume non-animal food.
Obligate carnivores are animals which survive solely on animal flesh for their nutrition requirement.
Examples are- lion, tiger, lizards.
A carnivore is always on the top of the food chain and they are not preyed upon by other animals.
So, option B is correct.
Option C) Herbivore: herbivores are the animals which are anatomically and physiologically adapted to eating plants and plant materials only.
Example- cows, horses, goats.
They have mouth parts designed in a way that are adapted to rasping and grinding.
In the food chain these animals are called primary consumers, as they are limited to only eating plants. They are an important link in the food chain as they connect plants by consuming them in return carnivores have them for the same reason.
They have different feeding strategies like- grazing and browsing.
Grazing animals like cows eat grass as forage up to ninety percent whereas browser animals like moose live on tree leaves and twigs.
So option C is not correct.
Option D) None of these: This option is incorrect as lizards come under the category of carnivore as they obtain their requirements on worm small insects as we discussed.
So option D is not correct.

So, option B is the correct answer.

Note:
Animals are dependent on each other for survival, direct or indirect.
Food chain has different levels based on the feeding styles of animals like primary consumers, secondary consumers, tertiary consumers.
Several food chain additions are known as food web.
