Front

What happens to other populations if the snake population is doubled?

Back

Grass and hawks will increase, rabbits will decrease.

Front

What limiting factor increases due to the number of individuals in a population?

Back

Disease.

Front

What type of relationship is exemplified by cattle egrets foraging among cattle?

Back

Commensalism.

Front

What characterizes a K-selected species?

Back

A K-selected species has a long lifespan, produces few offspring, and provides parental care.

Front

What is the carrying capacity for a sheep population if it is stated as 1.6 million?

Back

1.6 million.

Front

Define carrying capacity in population ecology.

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support.

Front

What is the difference between K-selected and R-selected species?

Back

K-selected species invest more in fewer offspring, while R-selected species produce many offspring with less investment.

Front

What is an example of a density-dependent limiting factor?

Back

Disease is a density-dependent limiting factor.

Front

What is mutualism?

Back

Mutualism is a symbiotic relationship where both species benefit.

Front

What is an example of a K-selected species?

Back

Elephants are an example of K-selected species.
