Bio Final Practice Spring 24

During a field trip, Ava, Aria, and Ethan observed a natural habitat. Based on their observations, which group would hawks and owls belong to based on their diet?

• Producers

• Consumers

• Decomposers

• Herbivores

In a school project, Luna, Abigail, and Harper are creating a food web diagram. Which of the following is a primary producer in their food web diagram?

• Mice

• Plants

• Spiders

• Foxes

In a forest ecosystem, what role do decomposers like fungi and bacteria play?

• They consume other animals

• They produce their own food using sunlight

• They break down dead material and recycle nutrients

• They help in pollination

What will MOST LIKELY happen if a new type of grass, known as Festuca Jamesii, is introduced into a local park's food web?

• The population of herbivores like deer and rabbits will increase.

• The population of carnivores like foxes will decrease.

• The population of omnivores like raccoons will decrease.

• The population of decomposers like earthworms will decrease.

Imagine a natural ecosystem where the following organisms make up a food chain: algae → fish → bear. Anika is studying this food chain for her biology project. If Anika were to place the bear into the trophic pyramid she created, the bear would go on level ____, and have ____ amount of energy available to it.

• A) C; the least

• B) A; the least

• C) B; an intermediate

• D) A; the greatest

A group of eagles observed by Elijah and Priya during their field trip around Lake Tahoe would be considered a(n):

• community

• ecosystem

• species

• population

Imagine a stable population of mice in Evelyn's backyard that has been constant for ten years. What would likely cause the number of these mice to begin to decrease?

• a decrease in competition between the mice

• an increase in predators (such as cats) who prey on them

• a decrease in disease among the mice

• an increase in mating season

Based on the chart, identify which of these events would harm the Georgia Black Bear population?

• Introduction of the bald eagle

• Restriction on humans hunting bears

• Damming lakes and rivers

• Large scale forest fires

During a biology class, Ava and Noah were discussing how termites are able to digest wood. They learned that termites feed on dead plant material and cellulose, which they find in wood. This is possible because of the bacteria and protists living in the termites' intestines. Zoe, curious about the nature of this interaction, asked what type of symbiotic relationship this is.

• Commensalism

• Mutualism

• Predatory prey

• Parasitism

While observing a farm, Aria noticed cattle egrets following the cattle. What type of symbiotic relationship do cattle egrets have with cattle, as described in the scenario?

• Parasitism

• Commensalism

• Predatory-prey

• Mutualism
