Answer: option C) species -> community -> biosphereD
Explanation:
Species refers to closely related organisms (plant or animal). When different species of organisms live together in a habitat where they feed on one another and become codependent on one another, a COMMUNITY has been formed. 
A BIOSPHERE, however is composed of many ecosystems i.e different species of plants, animals and microorganisms relating with their environment. Thus, a biosphere = Communities + environment

Light lets plants grow for the animals eat them
temperature lets the animals know when they have to hibernate or come out and hunt 
i think soil composition helps the animals to  get new types of food or lets them get water ?
