​

Answer 1

Answer:

a) The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5.

b) Energy flow in ecosystem - definition

Energy flow in ecosystem occurs by food chain from producer to consumers. The producers synthesise food and stores the energy from sun. E.g., green plants. ... Then energy is transfered from producers to consumers, called as heterotrophs. Primary consumers are called as herbivores.

c) The feeding positions in a food chain or web are called trophic levels. ... Humans, for example, are primary consumers when they eat plants such as vegetables. They are secondary consumers when they eat cows. They are tertiary consumers when they eat salmon.
