Can someone help plz!?

Biotic factors and abiotic factors, plant and light energy, herbivores, heterotrophs, omnivores, carnivores, primary consumer, decomposers and tertiary consumers.

Explanation:

Both biotic and abiotic factors are interacting with each other in an ecosystem. Plants use light energy from the sun to produce their own food. Herbivores are the organisms that feed on producers (plants). Heterotrophs are those organisms which are unable to make their own food. Omnivores are the organisms that eat both plants and animals. Carnivores feed on animals only. Primary consumers are the consumer which feed on plants. Decomposers helps in the breakdown of dead bodies of plants and animals. Tertiary consumers feed on secondary consumer.
