Biotic/ Abiotic Pictures






This picture includes 2 different types of limiting factors and both biotic and abiotic factors.
One limiting factor in this picture is the tree,
and the other is the sunlight shining through the tree and reflecting off of the road. The tree is a limiting factor because it limits the amount of sunlight and water that plants living underneath them receive. Sunlight is a limiting factor because sunlight is needed be every existing object in the universe. Therefore, the absence or presence of sunlight controls the patterns of life.
