What are the reasons for the change in amphibian populations?
The amphibian declines are linked to natural forces such
as competition, predation, reproduction and disease
, as well as human-induced stresses such as habitat destruction, environmental contamination, invasive species and climate change, researchers said.
What does the theory of natural selection predict will most likely happen to the population of seed eating birds over time?
What does the Theory of Natural Selection predict will happen to the population of seed-eating birds over time?

What type of limiting factor on population growth is human activities?
What limiting factors affect human population? The human population may be limited by
the availability of food and living space

Which represents the size of a population?
Population size is
the number of individuals in a population
. Population density is the average number of individuals per unit of area or volume. The pattern of spacing of individuals in a population may be affected by the characteristics of a species or its environment.
What do members of a population have in common?
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.
