Question

The least inclusive level of ecological organization that includes interactions among living and non-living factors
A. A Community
B. A population
C. A species
D. A biosphere
E. An ecosystem

Answer 1

Ecological organization can be studied at different levels, study at some levels related to the only living organism, at some level, it involves the study of both living and nonliving factors.

Step by step answer: The least inclusive level of organization that includes interactions among living and nonliving factors in the ecosystem. Ecological organization: Ecology is the study of the interaction between a living organism and their non-living environment, interaction among living organisms. And these interactions can be studied at different levels such as:-
a. Species: It is a group of organisms, which share some genetic similarity and on breeding produce fertile offspring. Organisms of one species on breeding with some other species do not produce offspring if they produce they are infertile.
b. Population: Population is the group of the organism of the same species residing in the same geographical condition. E.g. humans (Homo sapiens) are one species, but people living in Africa are one population, and people living in Europe are another one.
c. Community: Community refers to the population of different species living in the same area and interaction among them.
d. Ecosystem: An ecosystem includes both biotic and abiotic factors. It involves interaction between a living organism and their nonliving environment it includes population, community, and species.
e. Biosphere: Biosphere is the space on earth where life exists, it is the area of interaction between the hydrosphere, lithosphere, and atmosphere. It is a global ecosystem.

Note: Ecology is the study of the interaction between a living organism and their nonliving environment, interaction among living organisms. Study about species, community, population involves only study about the living organisms, not their surrounding environment but the ecosystem and biosphere include study both living and nonliving parts.
