Question

The graphic representation of the interrelationship between plant and animal is
A. Ecological niche
B. Ecological pyramid
C. A trophic level
D. None of the above

Answer 1

Directly or indirectly plant and animal depends on each other. Plants and animals have evolved together so they share a complex relationship.

Complete step-by-step answer:
A. Ecological niche: It is the ecological match of a species to the particular environmental conditions. It describes how an organism reacts to the distribution of the resources and the competitors. The ecological niche is a concept of central ecological biogeography.
B. Ecological pyramids: An ecological pyramid is a graphical representation between the different organisms at the different trophic levels. The primary producers are placed at the last of the pyramids and they absorb sunlight and transfer the energy to the other organisms. Each bar of the ecological pyramids represents a different trophic level and their order represents the flow of energy.
C. A trophic level: It is the level of organisms that occupies the position in the food web. The trophic level of organisms is the number of steps involved in the food chain. A trophic is a Greek word which means food and nourishment.
Hence, the correct option is B.

Note: Plants do not depend on the animals for their living. But some plants used animals for the transfer are nectar. There are three types of ecological pyramids: Pyramids of number, pyramids of biomass and pyramids of energy.
