Environmental - chapter 8: Populations

exponential growth

Growth pattern in which the individuals in a population reproduce at a constant rate

What would happen to a population if each pair of adults had two offspring and the offspring lived to reproduce?

It would remain the same

Flowering plants and their pollinators are an example of

a relationship that has coevolved

generation time

average age at which members of a species reproduce

The number of wild horses per square kilometer in a prairie is the horse populations

density

a butterfly pollinating a flower as it drinks nectar from the flower is an example of what?

mutualism

A kangaroo's role as a large herbivore on Australian grasslands is an example of:

niche

three lampreys attached to a fish and sucking its body fluids for food is an example of?

parasitism

All the black squirrels living in a forest is an example of what?

population

An owl snatching a mouse from a field to eat is an example of ________________.

predation

examples of exponential growth

rabbit populations after being introduced to Australia, . a bank account that earns interest, mold appearing on bread overnight

reproductive potential

the maximum number of offspring that a given organism can produce

Direct Competition

when individuals compete directly with each other for the same resources

Indirect Competition

when organisms use the same resource, but don't necessarily interact with each other

Parasitism

A relationship between two organisms of different species where one benefits and the other is harmed

What determines the carrying capacity?

The supply of the most limited resources

Competition for food can not occur

between animals from two different ecosystems

density independent

cause of death that does not occur more quickly in crowded populations

a large population of geese gathered in a marsh is an example of what?

clumped dispersion

an orchid using a high tree branch as a place of attachment to receive more sunlight but not affecting the tree is an example of what?

commensalism

Woodpeckers eating at a bird feeder would be an example of what?

competition
