Sunlight provides energy needed for photosynthesis
You failed to include the picture that goes with the question. However, the oldest fossils will be the fossils in the oldest layer, which is the lowest layer of sediment. Sedimentary rock forms as mud and silt pile up over thousands and millions of years. The layers of sediment harden and become rock. Organisms that are trapped in those layers become fossils as additional layers pile on top of them, forming new layers of sediment.
Since oomycetes are a fungi, they feed on decaying matter by absorbing the nutrients.
The correct answer is in the "chloroplast".
The chloroplast is considered to be <span>organelles, which are considered as specialized </span>compartments<span>, in plant and algal cells.</span>The main position<span> of chloroplasts is to aid the process of </span><span>photosynthesis, </span>in which<span> the photosynthetic pigment chlorophyll captures the energy </span><span>from </span>daylight<span> and converts it and stores </span><span>it </span>within the energy-storage<span> molecules known as ATP and NADPH </span>as freeing<span> oxygen from water.</span>
I think it’s b but I have no experience in this subject sorry
