Ecology Final Exam Review

Front

What interaction harms both species involved?

Back

Competition is an interaction that harms both species involved as they compete for limited resources.

Front

What is the process of combining nitrogen gas with other elements to make nitrogen into usable compounds?

Back

Nitrogen fixation is the process of converting nitrogen gas into usable compounds for organisms.

Front

What converts nitrogen gas into a usable form for plants and animals?

Back

Bacteria are responsible for converting nitrogen gas into a usable form for plants and animals.

Front

What best describes logistic growth?

Back

Logistic growth is population growth that is initially rapid, but begins to slow down as the population approaches its carrying capacity (K).

Front

True or False: Corridors are narrow patches that may act as links or barriers in a landscape, influencing dispersal of plants and animals.

Back

True. Corridors can influence the movement and dispersal of species.

Front

Define competition in ecology.

Back

Competition in ecology refers to the interaction between organisms or species in which both are harmed as they vie for the same resources.

Front

What is nitrogen fixation?

Back

Nitrogen fixation is the process by which nitrogen gas (N2) is converted into ammonia (NH3) or related compounds in soil.

Front

What role do bacteria play in the nitrogen cycle?

Back

Bacteria play a crucial role in the nitrogen cycle by converting nitrogen gas into forms that plants can absorb and utilize.

Front

Explain the concept of carrying capacity (K).

Back

Carrying capacity (K) is the maximum population size that an environment can sustain indefinitely without being degraded.

Front

What is the difference between logistic growth and exponential growth?

Back

Logistic growth includes a carrying capacity that limits population growth, while exponential growth occurs without such limits.
