Field mice are the primary food source for horned owls in an area. Due to a drought, many field mice left the area. Which result would this drought most likely have on the horned owls?

• The horned owl population will consume more field mice.

• Horned owls will follow the field mice to a different area.

• The horned owl population will increase in the area.

• Horned owls will change to a plant-based diet.

The levels of the ecosystem are:

• biosphere, individual organism, community, ecosystem, population

• individual organism, population, community, ecosystem, biosphere

• individual organism, community, ecosystem, population, biosphere

• ecosystem, community, biosphere, individual organism, population

The two factors that make up the ecosystem are:

• biotic factors (living factors); abiotic factors (nonliving factors)

• photosynthesis and cellular respiration

• carbon dioxide and oxygen

The Carbon Cycle shows...

• the movement of carbon on earth and how carbon enters the food chain

• the movement of oxygen on earth and it enters the food chain

• the movement of water on earth and how hydrogen enters the food chain
