A succession of organisms, which consumes other species and are being consumed by other organisms attaining distinct levels known as the trophic levels is in a combination called the food chain. On the basis of the 10% law of the transfer of energy, only 10% of the energy is mediated towards each of the trophic levels and the left gets lost during the process. Thus, if the producers are having 3000 calories of energy, the primary consumers will get 300 calories from them, and the secondary and the tertiary consumers will attain 30 and 3 calories respectively.
A food chain is a succession of organisms that eat other organisms and are being eaten by other organisms occupying different levels called the trophic levels. The first trophic level is occupied by the producers which include the plants, the second level includes the herbivores, the third level and subsequent levels represent the carnivores. The plants are called the producers since they can prepare their own food and the other organisms dependening on them are called the consumers.
According to the Ten percent law of energy transfer, only ten percent of the energy is transferred to each trophic level and the remaining is lost during the transfer. If the producers have 3000 calories of energy, the primary consumers obtain 300 calories from them. The secondary producers and tertiary consumers obtain 30 calories and 3 calories only.
If I have a batch of pea plants with purple flowers that I grew by crossing plants that had purple flowers (PP) with plants that had white flowers (pp), purple flowers (dominant) will be expressed in this batch of pea plants.
