Explanation:
During photosynthesis, molecules in leaves capture sunlight and energize electrons, which are then stored in the covalent bonds of carbohydrate molecules. That energy within those covalent bonds will be released when they are broken during cell respiration. How long lasting and stable are those covalent bonds? The energy extracted today by the burning of coal and petroleum products represents sunlight energy captured and stored by photosynthesis almost 200 million years ago.
Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis. Because they use light to manufacture their own food, they are called photoautotrophs (“self-feeders using light”). Other organisms, such as animals, fungi, and most other bacteria, are termed heterotrophs (“other feeders”) because they must rely on the sugars produced by photosynthetic organisms for their energy needs. A third very interesting group of bacteria synthesize sugars, not by using sunlight’s energy, but by extracting energy from inorganic chemical compounds; hence, they are referred to as chemoautotrophs.
Kinda like a pyramid. The bottom is wide, many sources of energy (plant life) that take nutrients combine them with water use the bonding of the suns rays and convert that to matter. This matter is then consumed by animals (grazers and browsers), who in turn are fed upon by predators. With man as the top predator.
Take a few seeds from wire-grass. Wire-grass grows in many natural communities, it is eaten by rodents and birds, like Quail. Quail are eaten by snakes, who are eaten by hawks, bobcats, and raccoons.
every time the meal is transferred from one critter to the next, energy is expended in the chase (heat) and capture, and energy is always being used for the animals to survive day by day.
Answer:We see the Moon because sunlight reflects back to us from its surface. During the course of a month, the Moon circles once around the Earth. If we could magically look down on our solar system, we would see that the half of the Moon facing the Sun is always lit. But the lit side does not always face the Earth. As the Moon circles the Earth, the amount of the lit side we see changes. These changes are known as the phases of the Moon and it repeats in a certain way over and over.

Explanation:
Heat therapy is said to work because of its analgesic properties or its ability to bring blood to the area which can penetrate deep into the muscular tissue. However, heat therapy is also said to work because it is comforting on a psychological level. According to Lorimer Moseley “to reduce pain, we need to reduce credible evidence of danger & increase credible evidence of safety” and applying heat makes us feel safe. Why? Because the cold kills!
Despite this, there is little evidence to show that it helps alleviate pain at certain trigger points (small patches of acutely sensitive soft tissue) in the body and there is less evidence to show that it works for period pain. One study has claimed that heat can work for period pain however the researchers failed to differentiate if their exercise programme or the psychological effect of feeling warm eased their pain. This kind of testing means that other variables influence participants’ perception of pain and we can’t be certain if the heat therapy actually helped. What we do know is there are certainly drawbacks to this kind of treatment.
