Question

Which one of the following animals may occupy more than one trophic level in the same ecosystem at the same time?
(a) Sparrow
(b) Lion
(c) Goat
(d) Frog

Answer 1

Hint: There are unique interactions and relationships which are involved within the transportation of energy. The energy, once produced and captured, is distributed throughout the varied living organisms. The linking of food habits depends on available food.

Complete step by step answer:
An organism which will occupy over one trophic level simultaneously is a sparrow. Sparrow is a primary consumer when they feed on seeds, fruits, peas, and a secondary consumer when they feed on insects and worms.
The three basic ways during which organisms get food are as producers, consumers, and decomposers. - Producers (autotrophs) are typically plants or algae. Plants and algae don't generally eat other organisms, but take nutrients from the soil or the ocean and manufacture their own food using photosynthesis. For this reason, they are called primary producers. Thus, it is energy from the sun that generally powers the base of the food chain. - Consumers (heterotrophs) are species that can't manufacture their own food and wish to consume other organisms. Animals that feed on primary producers are called herbivores. Animals that eat other animals are called carnivores, and animals that eat both plants and other animals are called omnivores. - Decomposers (detritivores) break down dead plants and material and waste and release it again as energy and nutrients into the ecosystem for recycling.
So, the correct answer is ‘(a) Sparrow’.

Note:
- Plants and algae prepare their own food and are known as producers. - Herbivores feed on plants and are known as primary consumers. - Carnivores that feed on herbivores are known as secondary consumers. - Carnivores that feed other carnivores are known as tertiary consumers. - Apex predators by definition haven't any predators and are at the highest of their food cycle.
