Answer and Explanation:
Community ecology is a discipline that studies the organism's communities and the manner in which populations of species interact with each other within a particular habitat. Mark Vellend is an eco-evolutionist that developed a theoretical framework of ecological communities from a unified functional perspective. This theory is based on four forces of evolutionary biology: selection, drift, dispersal and speciation. This theory is used to explain how species interactions including parasitism, competition and predation may influence population fluctuations. On the other hand, this theoretical framework can also be used to understand how colonization, disturbance and habitat suitability components alter the dynamics of interacting species.
The plant cell referred to in the question is attached to this answer.
The structure in the plant cell that represent the sites of ATP production from photosynthesis is the CHLOROPLAST; THAT IS OPTION B.
The photosynthesis reaction is divided into two stages, which are the light reaction and the dark reaction. The light reaction takes place in during the day in the presence of sunlight and it is during this period that ATP molecules are formed in the stroma of the chloroplast. During the dark reaction, the ATP produced during the light reaction together with NADPH are used as source of energy and reducing power respectively to manufacture carbohydrate from carbon dioxide.
