From the description you make, it's likely that the structure with letter A is the chloroplast. It is round and small and it's free because of the pigment needed for photosynthesis (chlorophyll). It is located inside the cell, suspended in the cytoplasm.
Soil respiration refers to the production of carbon dioxide when soil organisms respire. This includes respiration of plant roots, the rhizosphere, microbes and fauna. Soil respiration is a key ecosystem process that releases carbon from the soil in the form of CO 2 . CO 2 is acquired from the atmosphere and converted into organic compounds in the process of photosynthesis. Plants use these organic compounds to build structural components or respire them to release energy. When plant respiration occurs below-ground.

The one-way parasitism and predation differ - Predation results in death while parasitism does not.
A parasite
- generally, a smaller organism that depends on a larger organism.
- It does not directly cause death to the host though it may transmit pathogens.
- Parasites are usually host-specific.
A predator
- could be smaller or larger than the prey
- kills the prey in order to consume it for its own growth.
- Predators can hunt alone or in packs, and they are not prey-specific but can hunt a range of potential prey.
Thus, the one-way parasitism and predation differ - Predation results in death while parasitism does not.
