This picture depicted above is an example of parasitism. There is hair lice on my head, which is an example of parasitism because the hair lice is living on my head while damaging my scalp. The hair lice is harming me. The definiton of parasitism is two organisms interacting with each other while one benefits and the other is harmed from the interactions. So, having hair lice on my head is an example of parasitism.

The a-biotic limiting factor. This is a picture of clouds. This is an a-biotic limiting factor because they limit plants with their growth. They block the sunlight so the plants can't do their process of photosynthesis. They also take water from the plants, animals and people. Plants lose some of their water from evaporation and animals lose their drinking water as well as humans. This is limited because more and more water is leaving the streams and oceans. This picture was taken in the East Coast.
