Answer 1

ANS. (E)

characteristics of a population

A population is defined as a group of individuals of the same species living and interbreeding within a given area. Members of a population often rely on the same resources, are subject to similar environmental constraints, and depend on the availability of other members to persist over time.

A population is defined as a group of organisms of the same species that live in a particular area. There can be more than one population living within any given area. A species is a group of organisms that share similar characteristics and a species can live within many different areas.

Interactions between two or more species are called interspecific interactions—inter- means "between." Organisms of two species use the same limited resource and have a negative impact on each other. A member of one species, predator, eats all or part of the body of a member of another species, prey.

Inbreeding will increase the relatedness between individuals in a population. Interbreeding refers to reproduction with another species (or race), and is often used as a synonym to crossbreeding or hybridization (when referring to hybrid offspring from two different species/races/breeds, not DNA hybridization)

Population biology is a subset study within ecology that evaluates factors that affect populations. A population is defined as a group of the same species living in a similar geographical area. All life can be studied within this field, from mountain gorillas in Africa to passenger pigeons in North America.

In biology a population is all the organisms of the same group or species, which live in a particular geographical area. The area of a sexual population is the area where inter-breeding is potentially possible between any pair within the area, and where the probability of interbreeding is greater than the probability of cross-breeding with individuals from other areas.

The population has the following characteristics:

• Population Size and Density:
• Population dispersion or spatial distribution:
• Age structure:
• Natality (birth rate):
• Mortality (death rate):
• Vital index and survivorship curves:
• Biotic Potential:
• Life tables:
