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.
Transport of sediments causes them to become rounder as their irregular edges are removed both by abrasion and corrosion. Beach sand becomes highly rounded due to its endless rolling and bouncing in the surf.
Although the total energy received by our planet — and hence, Earth’s total temperature — isn’t affected by our axial tilt, the energy received as a function of latitude is very sensitive to it.
