The are 4 levels in total in the Trophic Levels, namely:

Producers: Plants that undergo photosynthesis to convert sunlight into energy that will later be spread among the consumers in the above levels.

Primary Consumers: Those organisms consume plants and around 100 kcal is available to them for each producer they eat. These organisms are mostly herbivores.

Secondary Consumers: They get around 10 kcal for each primary consumer they eat. They comprise of carnivores and omnivores.

Tertiary Consumers: They are at the top of the food chain and almost all food cycles end with them. They consume about 1 kilocalorie for each secondary consumer that they eat.

The nutrients follow the cycles collected from the surroundings of the plants, passed through the consumers and finally gets returned to the environment by detritivores. Energy is steadily lost as it moves along the food chain.

The thing in Trophic Levels is that only about 10% of the energy from one level is passed on to the next. As a result, the biomass of producers is definitely way larger than that of tertiary consumers. This explains why very few large predators can survive in the ecosystem as hardly any energy is available to sustain them.

4 question sir

4)

The ecosystem on earth will experience a disastrous change and It will be brought back on track soon due to the ability to recover.

Because the balance between herbivores and carnivores has been destroyed. Herbivores are fed on the flora and the total amount of flora on our earth can only sustain a limited number of herbivores.

We all know all creatures have the instinct of excessive reproduction. When carnivores exist, the number of herbivores is not able to grow limitlessly Because carnivores control the scale of herbivore herds by predation.

If all carnivores are removed, herbivores will reproduce dramatically and the increase of number will soon be out of control. More herbivores mean a larger need for food to feed them. And the flora will be consumed faster and flora will lose the ability to grow and produce food sustainably. The herds of herbivores will soon suffer from famine.

send me very simple answer sir please
