Explanation:
adaptations.
Natural selection leads to traits called adaptations, which improve an organisms ability to survive and reproduce.
Red algae can grow at deeper depths when compared to other algal groups because they are adapted to absorb blue light, which is required for photosynthesis.
Explanation:
Red algae, also known as rhodophyta, usually occur in the depths of seas. This is because of a unique adaptation in their structures, due to the presence of phycoerythrin - a pigment that reflects light that is red, while equipping the algae to absorb blue light. Hence, the algae appears red in colour.
All plants (including algae) require sunlight to be able to synthesize their own food through the process of photosynthesis. For plants that live in the oceans, the sunlight penetrating the waters is the only source of radiation in this regard.
The blue light in the radiation spectrum has the characteristic features of having the highest energy, as well as the shortest wavelength. This makes it the most energetic section of light, enabling it to penetrate to the ocean depths.
The phyrcoerythrin in the red algae absorbs this blue light for photosynthesis. This process occurs even at depths upto 500 feet, hence becoming an adaptive advantage for red algae to be able to survive at greater depths.
Answer:
Catabolism
Explanation:
Catabolism refers to the metabolic pathways to break down the complex biomolecules into simpler substances and release the energy stored in their chemical bonds.
The catabolic reactions are oxidizing reactions and remove the electrons from the substances.
For example, cellular respiration is a catabolic pathway for glucose as it oxidizes glucose into CO2 and H2O. During aerobic cellular respiration, molecular oxygen serves as the terminal electron acceptor and is reduced into water.
