Question

How is an organism different from a population?

Answer 1

Hint: An ecosystem used to describe both the biotic and abiotic factors in a system. The ecosystem is made up of birds, frogs, fungi, plants, mammals, bacteria, the water, the sun, the rocks, the soil, and so forth.

Complete answer:
An organism is used to describe an individual. For example, you are an organism. I am an organism and all of us are organisms. An organism is a single, living thing and can be an animal, a plant, or algae. They grow and respond to their environment. In the ecosystem, it is the lowest level of organization which includes both unicellular and multicellular organisms.

A population used to describe a group of individuals or organisms of a single species that live within a particular geographic area. They all belong to the same species. They interbreed and give rise to new offspring. A metapopulation is a term used to describe when individuals in local populations scatter between other local populations. Most of the populations are not stable and cannot follow exponential growth due to various physical factors in the environment which act as limiting factors.

Note: There are five levels of organization in an ecosystem and are listed according to their size – Organism is the smallest level of organisation followed by population then community, ecosystem and biosphere is the largest level of organisation.

The ecosystem is of very much importance to all organisms because
- It provides a habitat for wild plants and animals.
- It promotes various food chains and food webs.
- It controls essential ecological processes and promotes life.
- Involved in the recycling of nutrients.
- Maintenance of the usual flow of energy in an ecosystem including- Carbon Cycle, Energy Cycle, Nitrogen Cycle, Oxygen Cycle, and Water Cycle.
