A. Biotic elements are the weathered rock and leaf litter. These elements interact with the organisms, heat and light (abiotic) to help produce a soil structure.

B. Biotic elements are part of the structure of a food chain. The biotic elements provide the building blocks of life. The abiotic elements feed off the biotic elements in the food chain.

C. Biotic elements are responsible for processes such as leaching and decomposition. Abiotic elements provide the raw materials (such as water) which allow life to flourish.

D. Biotic elements are the living part of an ecosystem such as micro-organisms, plants and animals. Life is supported by the abiotic elements such as weathered rock, climate and various gases.
