Question

Fill in the blanks with suitable word:
All non-green plants and animals are_______

Answer 1

Hint: The non-green plants and animals lack a pigment named as chlorophyll which is essential for the photosynthesis.

Complete answer:
In order to solve this question, we need to know about nutrition and photosynthesis.

Nutrition: It is defined as a process of taking in and utilizing food for the growth, metabolism, and repair of an organism.

Photosynthesis: It is a process in which organisms like green plants and some other organisms like prokaryotic bacteria convert light energy into chemical energy.

Light energy is used to convert water, carbon dioxide, and inorganic compounds into oxygen and energy rich organic compounds.

So, on the basis of organisms which can and cannot perform photosynthesis, nutrition in organism can be divided into following types:

1. Autotrophic Nutrition (Plants, algae, cyanobacteria)
2. Heterotrophic Nutrition
   - Saprophytes (mushroom)
   - Parasitic (leeches)
   - Holozoic (humans)

Heterotrophic Nutrition: It is the type of nutrition in which organisms are not able to prepare their own food and depend upon others (autotrophs) for the nutrition.
These types of organisms are known as Heterotrophs.
For example: Non-green plants, mushrooms, ticks and animals including human beings.

So, all non green plants and animals are known as heterotrophs.

Note: Autotrophic Nutrition is a type of nutrition in which organisms can prepare their own food by the process of photosynthesis.
So, these types of organisms are known as autotrophs.
For example: Green plants, algae, some bacteria.
