Generation of carbonates from burnt plant material following fire disturbance causes an initial increase in soil pH that can affect the rate of secondary succession, as well as what types of organisms will be able to thrive. Soil composition prior to fire disturbance also influences secondary succession, both in rate and type of dominant species growth. For example, high sand concentration was found to increase the chances of primary Pteridium overImperata growth in Imperata grassland. The byproducts of combustion have been shown to affect secondary succession by soil microorganisms. For example, certain fungal species such asTrichoderma polysporum and Penicillium janthinellum have a significantly decreased success rate in spore germination within fire-affected areas, reducing their ability to recolonize.

Nucleic acidsNucleic acids are the biopolymers, or small biomolecules, essential to all known forms of life. The term nucleic acid is the overall name for DNA and RNA. They are composed of nucleotides, which are the monomers made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base.
Answer is D.form polysaccharides
Answer:
Plant cells need both chloroplasts and mitochondria because they perform both photosynthesis and cell respiration.
Explanation:
Chloroplast converts solar energy into chemical energy during photosynthesis, while mitochondria, the powerhouse of the cell, produces ATP- the energy currency of the cell during respiration.
