The correct sequence of levels of ecological organization from smallest to largest is Organism, Population, Community, Ecosystem, and Biosphere. Hence, the correct answer is option (b).
Which is the correct order of ecological hierarchy?
Every species existing in the universe makes the ecology. So the hierarchy places them in order- individual, population, community, ecosystem, biome, biosphere.
What are the five levels of ecological hierarchy?
Within the discipline of ecology, researchers work at five broad levels, sometimes discretely and sometimes with overlap: organism, population, community, ecosystem, and biosphere.
What is ecological hierarchy?
Ecological hierarchy theory describes the arrangement of biological organisms in relation to one another. At the simplest level of the hierarchy are individual organisms. … Moving up the hierarchy, ecologists have found more complex ways to describe the relationships between organisms.
Which is the correct order of ecological hierarchy biome population community organism?
Detailed Solution. The correct answer is Population → Landscape → Community → Ecosystem. Population → Landscape → Community → Ecosystem is the correct order of biological organization ranging from organism to biosphere.
What is correct for ecosystem?
An ecosystem may be defined as a structural and functional unit of the biosphere comprising living organisms and their non-living environment that interact by means of food chains and chemical cycles resulting in energy flow, biotic diversity and material cycling to form a stable, self supporting system.
What are the 4 levels of ecology?
Ecology is the study of the interactions of living organisms with their environment. Within the discipline of ecology, researchers work at four specific levels, sometimes discretely and sometimes with overlap. These levels are organism, population, community, and ecosystem.

What is the correct order of organization from least to most complex?
The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
What factors determine ecological hierarchy?
Individuals make up a population; populations make up a species; multiple species and their interactions make up a community; and multiple species and their interactions make up ecosystems when you include the abiotic factors. This is the hierarchy of ecology.
What is ecological hierarchy shaala?
The gradual (and predictable) change in the species composition of a given area is called ecological succession.
Which of the following is highest level in ecological hierarchy that is consist of only biotic factors?
The correct answer is 4. Biosphere.
Which of the following is correct for the r selected species?
So, the correct answer is ‘Large number of progeny with small size’. Note: – r-selected species are also called fugitive species or opportunistic species. – Mac Arthur and Wilson designated the terms ‘r-selection’ and ‘k-selection’.
What is ecological equivalent?
Ecological equivalents : species that use similar niches in different habitats or locations are called ecological equivalents . The evolution of life has resulted in general types of habitats and certain successful ways of exploiting the resources in those habitats.
What is the study of Synecology?
synecology (or community ecology) refers to the study of groups of organisms in relation to their environment.
