Hint: The earth has two components one which is living and another one on which these living organisms depend on for their survival the non-living things like land, water, sunlight etc.
Biotic components are also called biotic factors, they include any living organism that affects positively or negatively the life of another living organism in the referred ecosystem. This will include heterotrophic carnivorous animals and prey.

Complete Answer:
Biotic components include:
1) Producers- These organisms are also called autotrophs as they prepare their own food with the help of photosynthesis and include trees, herbs, shrubs, and other plants and cyanobacteria. There are some other bacteria which make their food with the help of chemicals and are known as chemosynthetic bacteria. They release sulphur in the place of oxygen mostly.
2) Consumers- These organisms are also called heterotrophs and are dependent on the autotrophs directly or indirectly for their energy requirement. Heterotropic herbivores consume plants as a source of nutrition. Heterotropic carnivores on the other hand consume other animals as their source of nutrition.
3) Decomposers- These organisms are also known as detritivores. They are heterotrophic saprophytes which consume dead and decaying matter also called detritus.

So the correct answer is 'Plants and animals'.

Note: Abiotic components are the essential part as they are necessary for the survival of the biotic component. Air, water, land etc are known as abiotic components and provide essential things to the living organism like oxygen to live, habitat to stay. But as human activities are increasing they are exploiting the natural resources like delay in water cycle, impure air to live etc.
