Answer:
The correct answer is A. scavengers and B. producers
Explanation:
Two types of factors are found in a biome biotic and abiotic factor. All the living things in any biome comes under biotic factors like animals, plants, and microbes and all the non-living things present in the biome are non-biotic factors for example soil, temperature, air, water, salt, etc.
So biome is made up of both living and non-living factors. Scavengers are the organisms that feed on dead and decaying matter and producers are the organisms that make their own food. Most of the producers are plants.
So both scavengers and producers are living organisms therefore both are examples of biotic factors.
