the populations of producers
the number of predators
the color of the water
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.
Which population would be most affected if there is a decrease in the population of aquatic insects?
squirrel
moose
dog
frog
Which species are best able to occupy the same space?
those whose needs differ significantly from each other
those that eat the same foods
those that compete for the same resources
those that have a predator/prey relationship
Which best describes the way photosynthesis provides resources to animals?
Photosynthesis produces excess moisture from the plants, reducing the need for a water supply.
Photosynthesis increases plant growth, providing places for many animals to live
Photosynthesis produces carbon dioxide, decreasing the animal’s need for oxygen.
Photosynthesis increases plant growth, providing food for carnivores and eliminating the need to hunt.
Deer are introduced into a grassland ecosystem and their population increases considerably. If the deer population continues to grow, which is the most likely outcome for the ecosystem?
Biodiversity would decrease, and sustainability would decrease.
Biodiversity would increase, and sustainability would decrease.
Biodiversity would increase, and sustainability would increase.
Biodiversity would decrease, and sustainability would increase.
A baby kit fox grows to become an adult with a mass of over 3.5 kg. What factor will have the greatest influence on this kit fox’s survival?
the average number of fox offspring
the conditions of the fox’s habitat
the size of the fox’s ears

A rainforest area is experiencing a severe drought. As a consequence, the insect population has decreased. What will the insect-eating birds most likely do as a result of the drought?
stop searching for food until it begins to rain
begin reproducing to increase population
move to a new area to find food
start the process of hibernation
Which is an abiotic factor that would affect the growth of a population within an ecosystem?
the type of herbivores present
the availability of water
the availability of producers
the number of carnivores present
When an ecosystem is affected by the loss of shelter, what happens to the populations in that ecosystem?
They are usually not affected
