Solution

a. Carnivores occupy the third trophic level in the food chain because the second level is occupied by herbivores. Herbivores are organisms who feed on plants. Carnivores occupy the next level after herbivores.

b. The flow of nutrients in an ecosystem occurs in a cyclic manner. The continuous transfer of nutrients which are necessary for the growth of organisms occurs from abiotic to biotic factors and biotic to abiotic factors in an ecosystem. This nutrient cycle operates continuously through the biosphere formed by lithosphere, atmosphere and hydrosphere.

c. Plants in an ecosystem are called primary producers. Plants are autotrophs who can produce their own food and other organisms are dependant on them to meet their nutritional requirements.
