Day 4 Biology STAAR review Organism behavior

The animal in an ecological relationship that results in another animal being hunted, killed, and eaten…

• autotroph

• habitat

• predator

• herbivore

• producer

An ecological symbiotic relationship between two organisms where one benefits and the other is harmed…

• parasitism

• herbivore

• mutualism

• carnivore

• commensalism

This is the job or role of a specific organism within its habitat...

• producer

• prey

• carnivore

• niche

• photosynthesis

What you would call an ecological symbiotic relationship between two organisms where one benefits, but the other is not helped or harmed?

• mutualsim

• predator

• commensalism

• parasitism

• herbivory

The name of the process that producers use to make their own food…

• respiration

• commensalism

• food chains

• photosynthesis

• symbiosis

What ecological relationship is depicted between Pumba (warthog) and the bugs?

• Competition, because pumba is in competition with the bugs for food sources

• Mutualistic, because Pumba and the bugs benefit each other

• Predator-Prey, because Pumba is a predator that consumes bug as prey

Marlin and his son, Nemo, are clownfish that live in a sea anemone. Clownfish benefit by receiving protection and shelter from the sea anemone. The clownfish, in return, scares away predators of the sea anemone and provides nutrients for the sea anemone through its excrement (waste). The symbiotic relationship between Nemo and the sea anemone is known as -

• parasitism

• commensalism

• predator-prey

• competition

• mutualism

The pearlfish receives protection from predators by living inside a sea cucumber. The sea cucumber is not affected during this interaction. This ecological relationship is known as -

• predator-prey because the pearlfish is prey to the sea cucumber

• mutualism because only the pearlfish benefits in this ecological relationship

• parasitism because the pearlfish causes harm to the host sea cucumber

• commensalism because only the pearlfish benefits while the sea cucumber is not affected

• competition because the sea cucumber and pearlfish often fight for living space

The food webs model relationships among the organisms in two ecosystems.

Which ecosystem would be more likely to survive if a disease killed the grasses?

• The forest ecosystem, because most of the animals can eat other organisms.

• The grassland ecosystem, because several predators compete for food.

• The forest ecosystem, because it has three top predators.

• The grassland ecosystem, because it has many herbivores.

The figure above shows the same ecosystem in Texas at two different times.

Which of the following MOST likely caused the change of species shown in the figure?

• development of a parking lot

• passing through of a glacier

• preservation of habitat

• occurrence of a forest fire
