APES Unit 3 Part 1

Members of an r-selected species characteristically

• larger-bodied

• put energy into reproduction not survival

• good competitors

• are very protective of their offspring

The K-selection reproductive strategy maximizes survival of offspring by producing

• many offspring with low levels of parental care

• few offspring with low levels of parental care

• many offspring with high levels of parental care

• few offspring with high levels of parental care

Members of an r-selected species characteristically

• grow slowly

• produce few offspring

• reach sexual maturity quickly

• have long life spans

• are very protective of their offspring

What is a generalist species?

• Species with a broad range of tolerance

• Species with a narrow range of tolerance

This type of species has many offspring with little to no parental care.

• k-selected

• r-selected

• s-selected

• j-selected

Bacteria, algae, and dandelions are an example of

• r-selected species

• k-selected species

• s-selected species

This type of species population remains close to carrying capacity (k) over long periods of time.

• r-selected

• k-selected

• s-selected

humans, polar bears, and elephants are an example of

• r-selected species

• k-selected species

• j-selected species

Long life span

• K-selected

• r-selected

many years to reach reproductive maturity

• K-selected
