The correct answer is - cyanobacteria.
The atmospheric oxygen came from the cyanobacteria. These were one of the earliest living organisms on Earth. The cyanobacteria was using photosynthesis in order to create its own food. The photosynthesis process requires sunlight, carbon dioxide, water, and oxygen. The oxygen is mostly released as a waste product from the process of photosynthesis, thus the cyanobacteria were literally releasing oxygen that was ending up into the atmosphere. As more and more cyanobacteria there were across the planet, more and more oxygen they were releasing into the atmosphere, slowly changing the composition of the atmosphere, and setting the basis of it as we know it now.
Ecozone is
divergent environment wherein the biotic community, plants, animals and people
and non-biotic community, lithosphere, atmosphere and hydrosphere communicate
and process.

Hence, Conservationists
that are inclined and supports the proper usage of the natural resources are
able to identify areas and resources that are being misused. They are also able to prevent and report such possible threats to the environment and helps maintain and sustain the ecological system. This will increase the chances to avoiding climate change to a great extent.

Interquartile range, part of the descriptive statistics is where you measure the between the difference of Q1 and Q3. Q2 is then the interquartile range. Further, interquartile range is the midpoint or the mid-spread of the data given.
This is true that mixed-phase clouds over the southern ocean as observed from satellite and surface-based lidar and radar.
A three-phase colloidal system made up of water vapor, ice particles, and coexisting supercooled liquid droplets is represented as mixed-phase clouds. At all latitudes, from the arctic regions to the tropics, mixed-phase clouds are common in the troposphere. Due to their extensive nature, mixed-phase processes are crucial to the radiative energy balance on both a regional and global scale, precipitation generation, cloud electrification, and the life cycle of clouds.
But despite decades of theoretical research and observation, our knowledge and understanding of mixed-phase cloud dynamics are still lacking. The representation of mixed-phase clouds in numerical weather and climate models is famously challenging, and it is still challenging to describe them in theoretical cloud physics.
