Q.Define population and community.

Population = individuals of one species in an area; Community = all interacting populations of different species in an area.

In ecology, living organisms are organised at increasing levels of complexity. Two important levels are:

• Population: a group of individuals belonging to the same species that live together in a particular geographical area at a given time and are capable of interbreeding. Example: all mango trees in a garden. …

A population = individuals of one species in an area; a community = all the different-species populations living together in that area.

Definitions:

Population:

• A population is a group of individuals belonging to the SAME species that live together in a particular area at a particular time, sharing common resources and capable of interbreeding.

Community:

• A community (biotic community) is an assemblage of populations of DIFFERENT species that live together and interact with one another in a common area or habitat. …

A community is the group of all populations of different species living together in an area; Warming classified plant communities into hydrophytes, mesophytes and xerophytes.

Definition:

• A biotic community is an assemblage of populations of different species that live together and interact with one another in a common area or habitat.

Classification of plant communities:

• On the basis of the availability of water in their habitat, plant communities were classified into three ecological groups - hydrophytes (plants of water), mesophytes (plants of moderate water) and xerophytes (plants of dry habitats). …

Population = individuals of one species in an area; Community = all interacting populations (many species) in that area.

Population: A population is a group of interbreeding individuals of the same species occupying a particular area at a particular time.

For example, all the mango trees in a garden form a population.

Community: A biotic community is an assemblage of all the populations of different species that live together and interact with one another in a given area.

For example, the trees, shrubs, herbs, animals and microbes of a forest together form a community. …

A community = all populations of different species living together and interacting in an area. Warming classified plants into hydrophytes, mesophytes and xerophytes (based on water availability).

A biological (biotic) community is the assemblage of populations of all the different species that live together and interact with one another in a particular area or habitat. For example, all the plants, animals and microbes in a pond form a community.

On the basis of the availability of water in their habitat, plants were classified by the botanist Warming into three ecological groups:

• Hydrophytes — plants growing in or near water.
• Mesophytes — plants of ordinary/moderate water supply. …
