Dispersal is a common component of the life cycles of plants and animals.
Colonization of devastated areas after floods or volcanic eruptions depends on dispersal.
Dispersal occurs only on an evolutionary time scale.
Seeds are important dispersal stages in the life cycles of most flowering plants.
Young salmon imprint on the chemical scent of their home stream.
Adult salmon use stellar navigation to relocate their home stream.
Spawning in the home stream results in higher survival of young salmon.
Oceanic currents aid salmon in their search for their home stream.

Genes have very little influence on the expression of innate behaviors.
Innate behaviors tend to vary considerably among members of a population.
Innate behaviors are limited to invertebrate animals.
Innate behaviors are expressed in most individuals in a population across a wide range of environmental conditions.
The size of the area occupied by the population is increasing.
Resources are distributed unevenly.
The members of the population are competing for access to a resource.
The members of the population are neither attracted to nor repelled by one another.

Two species cannot coexist in the same habitat
Competition between two species always causes extinction or emigration of one species
Competition in a population promotes survival of the best-adapted individuals

Limitation of plant biomass by rainfall amount
Influence of termperature on competition among plants
Influence of soil nutrients on the abundance of grasses versus wildflowers
Effect of grazing intensity by bison on plant species diversity
There are not enough organisms to fill more than five levels.
There is too much competition among the organisms at the lower levels to support more animals at higher levels.
Energy is lost at each trophic level.
The statement is not true; there can be unlimited trophic levels.
