The two main factors of an ecosystem are the biotic and abiotic things found in that environment. Biotic factors are all of the living parts of the ecosystem, such as plants and animals. Abiotic factors are all of the non-living parts of the ecosystme, such as the physical landscape, sun, and clouds.
The video described three ecosystems: Desert, Tropical Rainforest, and Temperate Deciduous Forest.
Choose ONE of the ecosystems from the video, and create a list of biotic (living) and abiotic (non-living) factors found in that ecosystem. You can rewatch the video for examples, or look online for ideas. Include at least 10 biotic factors and 5 abiotic factors.
