Ecological Parameters

Ecological parameters are the measurable characteristics of the ecosystem that provide information about its structure and function. These parameters are used to study the ecological relationships and interactions between different organisms in the ecosystem. Some of the ecological parameters are:

- Number: It refers to the population density or abundance of a particular species in the ecosystem.
- Energy: It refers to the flow of energy through the food chain and is measured in terms of productivity and consumption.
- Biomass: It refers to the total mass of living organisms in the ecosystem and is an important indicator of the ecosystem's productivity and health.
- Stratification: It refers to the vertical layering of the ecosystem based on the distribution of temperature and light.

Answer

The correct answer is option 'A' which is Stratification because it is not an ecological parameter, but a physical parameter that affects the distribution of organisms in the ecosystem.

Explanation

Stratification is a physical parameter that is caused by the distribution of temperature and light in the ecosystem. It results in the vertical layering of the ecosystem and affects the distribution of different organisms in the ecosystem. For example, in aquatic ecosystems, the distribution of organisms is affected by the temperature and light gradient that exists in the water column. The warmer and well-lit surface layers are occupied by phytoplankton, while deeper layers are occupied by zooplankton and fish.

On the other hand, ecological parameters are the measurable characteristics of the ecosystem that provide information about its structure and function. These parameters are used to study the ecological relationships and interactions between different organisms in the ecosystem. For example, the number of individuals in a population, the amount of energy flowing through the food chain, and the total mass of living organisms in the ecosystem are all ecological parameters that provide important information about the ecosystem's structure and function.

In conclusion, stratification is not an ecological parameter, but a physical parameter that affects the distribution of organisms in the ecosystem.
