Answer:
I think there is more oxygen in the troposphere because the closer you get to earth, the more oxygen there is. The troposphere is very close to the earth, therefore, there is lots of oxygen in the troposphere.
1) Ecology is the scientific study of the distribution and abundance of organisms, the interaction among organisms, and the interactions between organisms and their abiotic environment. Ecologists try to understand the inner workings of natural ecosystems and the species they contain.
2) Ecosystems have no particular size. An ecosystem can be as large as a desert or a lake or as small as a tree or a puddle. If you have a terrarium, that is an artificial ecosystem. The water, water temperature, plants, animals, air, light and soil all work together.
3) The biotic factors of an ecosystem include all the populations in a habitat, such as all the species of plants, animals, and fungi, as well as all the micro-organisms. Also recall that the nonliving factors are called abiotic factors. Abiotic factors include temperature, water, soil, and air.
4) For aquatic ecosystems, these factors include light levels, water flow rate, temperature, dissolved oxygen, acidity (pH), salinity and depth.

Answer:
(A) True
Explanation:
Vitamins are important for the human body because it plays an important function in the body like in metabolism, calcium absorption, releasing energy from food, cell damage repair, etc.
For example, vitamin D can be made by the body itself. This vitamin is made by the skin when UV radiation from the sun falls on the skin. This vitamin act as membrane antioxidant and helps in inhibiting iron-dependent lipid peroxidation in cell's liposomes.
It also helps in calcium regulation in the body and without vitamin D the dietary calcium is not properly absorbed.
There are several stages but the crossing over starts on the second stage. And the actual crossing sides happens on the following stage. Hope this helped :)
Answer:
Oxygen and chemical energy
Explanation:
<h3>In the thylakoids of the chloroplast</h3><h3>6CO2 + 6H2O (In the presence of light) → C6H12O6 (Sugars) + 6O2.</h3>
