Salmon spend a tremendous amount of energy to make the journey from the ocean back to their home-stream. There, they lay many eggs and then die, providing no real parental care for their offspring (although the newly hatched salmon do feed on the bodies of the dead previous generation once they hatch). Salmon are an axample of a__________ species.

In ________ species the the birds the Lack studied from the recorded lecture last Wednesday, parent mortality and the ability to reproduce again in the future is an important consideration for reproductive fitness.

____ selected species generally undergo intense competition for resources and exist in an environment nearing carrying capacity. ____ selected species generally live in unpredictable, disturbance prone habitats where resources are abundant and competition is low.

r selected species typically have a type ____ survivorship curve, where there are many offspring produced but most of those offspring die off early in life.

___________ make their own food using inorganic sources of Carbon in the environment. When I look at a plant, which is an example of one of these organisms, what I'm able to see is the _____ of that plant, or the amount of organic matter that is available for consumption by herbivores (and later detritivores).

The two factors that influence the amount of primary production in an ecosystem are (choose 2)...

A lion and a hyena competing for the same prey is an example of competition. The effect on both species 1 and 2 is...

IntrAspecific competition is between members of...

When 1 species or individual denies another access to a resource by exploiting that resource first, like a nursery plant blocking the sun from a small desert cactus, this is an example of __________ competition.

A population of Drosophila melanogaster with 500 individuals and a carrying capacity of 1500 follows the logistic growth equation. Suppose that 500 individuals of a competitor species, Drosophila simulans, are added to the population, and that this species has an α of 0.2. One would predict that this number of competitive individuals will decrease the D. melanogaster population growth rate by the same amount as the addition of _______ D. melanogaster individuals would.

Suppose species 1 and species 2 are competing for a limiting resource. If species 2 goes extinct, what would the Lotka-Volterra model predict would happen to species 1?
