Answer:
<h3>An electric motor converts electrical energy into physical movement. Electric motors generate magnetic fields with electric current through a coil. The magnetic field then causes a force with a magnet that causes movement or spinning that runs the motor. Electric motors are used in all sorts of applications.</h3>
The astenosphere plays a key role in the plate tectonics theory because it is the one that provides the high temperatures, high pressure, and magma, that are the ones responsible for cracking up the crust on the surface.
The astenosphere, with the ability to crack the crust on the surface of the planet is creating the continental and oceanic tectonic plates, and it also provides the push force from bellow so that they can move across the globe and thus be creating the landscape on the planet.
Answer:
<u>Food chain as given below</u>
Explanation:
- A consumer is a living creature in the food chain that eats other consumers and maintains a balance in the food web. Primary producers are all green plants that prepare their food by their ability to utilize the sun's energy and convert that available raw energy into starch in their body by the process of photosynthesis.
- These Autotrophs take up the organic matter through their roots in the form xylem and phylum and giving oxygen in the air. They form the base of the food chain on which are dependent Herbivorous like sheep, goat, cow, etc.
- The secondary consumers are called the Carnivorous, like the lion, tiger, etc that feed on the bodies of herbivorous. Above this level is that of Omnivorous i.e both plant and animal eaters like the crow, man, and cat.
- As stated by the law of thermodynamics energy can neither be destroyed nor created but transforms itself. The flow of energy at each trophic level gets successively transferred to the next trophic level from primary to secondary tertiary and so on.
- Likewise, toxin concentration in trophic levels increased each level upwards and leads to biomagnification that is harmful to the entire food chain.
