Science & Technology Prelims Question

Consumers: These are heterotrophic organisms of the biospheric ecosystem, which include animals including man, which are further divided into primary consumers or herbivores, secondary consumers or carnivores and omnivores.
Decomposers: These are micro-organisms living in the soil which decompose and consume dead plants and animals, and are also called the detrivores.
Hologenic: Hologenic animals are those which take their food through their mouth, such as big animals. Examples - elephants, cows, camels etc.
Parasites: These are those animals which depend on other animals for their food and life.
Saprophytes: These are those animals which live on organic compounds in solutions form derived from dead plants and animals.
Primary producers: These plants are primary producers, because they produce their food themselves through the process of photosynthesis. Primary producers are also called autotrophs or phototrophs.
