Quantum Physics help us understand the properties of solids, atoms, nuclei, sub-nuclear particles and light.
The word quantum refers to discreteness.
Coral reefs<span> are also being degraded by many other factors. The list of problems can seem endless: overfishing, fishing using cyanide and dynamite, pollution from sewage and agriculture, massive outbreaks of predatory starfish, invasive species, and sedimentation from poor land use practices</span>
<span>The ecosystem is the lowest level of the biosphere hierarchy to include weather patterns and soil conditions.
in the whole biosphere hierarchy, ecosystem actually placed as the second highest (1 place below biosphere)
But there are only 2 hierarchy that include weather and soils, and those hierarchies are biosphere and ecosystem. So technically the ecosystem will be the lowest in this matter</span>
The neritic zone is permanently covered with generally well-oxygenated water, receives plenty of sunlight and has low water pressure; moreover, it has relatively stable temperature, pressure, light and salinity levels, making it suitable for photosynthetic life.
b)1 unicellular- means one cell
