<span>Jane's observation will be that in the transparent bottle, the algae and small plants present in the pond water release oxygen during photosynthesis, while in the dark bottle, photosynthesis doesn’t occur due to darkness. Therefore, oxygen in the transparent bottle is more than that in the dark bottle. In photosynthesis, photosynthesizing organisms, such are algae and small plants, use carbon dioxide and water and convert it into glucose and oxygen in the present of sunlight. Therefore, organisms in the transparent bottle can perform photosynthesis and consequently release oxygen. However, this is not the case with the dark bottle that cannot transmit the sunlight.</span>
<span>Although a star might look brighter than the Sun, a comparison of its absolute<span> magnitude might help prove that they have the same real brightness.
Absolute magnitude is a concept that compares the absolute brightness of celestial objects. The absolute magnitude of an object is defined as the apparent magnitude it would have if it were viewed at a standard distance of 10 parsecs (32.6 light-years) with no dimming of its light. The more luminous an object, the smaller the numerical value of its absolute magnitude.</span></span>

Answer:
Many activities of human alter the availability of water in ecosystem.
Explanation:
We know that water is an essential item for daily use and development works. Water is required for different development processes.
Although, the drinking of water is foremost work, but human beings utilize water into agricultural practices, industries, cleaning activities etc. These activities of human beings alter the availability of water in an ecosystem. Thank you
