The term ecosystem development to ecological succession was given by
A. Odum
B. Clements
C. Mishra
D. Blackman

Answer 1

Hint: Ecological succession is a process of progressive changes occurring in the composition of an ecological community over time. It leads to changes in the physical as well as biological component of an ecosystem. In this process, a biological community evolves. This occurs due to the effect of various factors on the ecology.

Complete answer:
A group of species that interact with each other is known as the community and when a group of communities connected through nutrient and water cycles forms an ecosystem.
Ecological succession is a term used to define the change in the structure of a community of different species or ecosystems. It is a constant and continual process in which the changes in a species in a given area in respect of the changes in the environment. It is an essential process of change of species in nature as all the living elements of an ecosystem have to survive with the changes in our environment.
Ecological succession takes place due to the purpose to achieve equilibrium in the ecosystem and which group of species achieves this equilibrium is known as a climax community. In the climax community, all of the resources are efficiently used. To reach the aim of equilibrium, species vary in number by increasing and decreasing in number. Eugene P. Odum was an American biologist who is worldwide famous for his pioneering work on ecosystem ecology. He gave the term ecosystem development to ecological succession.

Hence the correct answer to the question is option A.

Additional Information:
The different types of ecological succession are noticed at the different stages of an ecosystem. This classification depends on the development of the particular ecosystem. Basically, two main types of succession have been founded in an ecosystem. One is primary succession and the other is secondary succession. Primary succession can be seen in lifeless areas where the soil is incapable of sustaining life. In alter, we can say where life starts with the process of succession is known as primary succession. Secondary succession is seen in the areas where a previously existing community has been removed or when life starts at a place where the area has lost all the life forms that existed there, then the process will be defined as secondary succession.

Note: When a natural process of constant and continuous changes takes place in a community in an ecosystem over time to evolve the biological community the process is called ecological succession. An understanding of how communities form and change over time helps to understand the processes that affect biological communities. The term ecological succession was given by an American ecologist Odum.
