Looking at the energy pyramid, which organism provides the greatest amount of energy?
phytoplankton
zooplankton
predator fish
birds
These fungi are performing an important function in an ecosystem. That function is...
creating oxygen
making glucose
recycling nutrients
creating carbon dioxide
Within this food chain which organism has the greatest amount of energy?
large fish
algae
bears
small fish
Bears and wolves both eat large herbivores, like deer. If there are not enough deer in an ecosystem with bears and wolves, the two predators will fight over the prey. What is this type of relationship called?
commensalism
mutualism
parasitism
competition
Bacteria that live in the intestines of humans help to complete the digestive process. In return, the bacteria get nutrients and protection. This is an example of:
mutualism
parasitism
commensalism
competition
The flu virus is not considered a living thing but it depends on living cells for energy, reproduction, and protection at the expense of the cells they invade. This is an example of:
commensalism
parasitism
mutualism
competition

A tick living off the blood of a dog. The tick is helped but the dog is harmed.
A snake and a tortoise share a burrow. Both are helped.
A remora fish sticks to a shark and eats the scraps of food the shark leaves behind. The shark is not harmed
Bears and Wolves fight over a deer kill.
If a group of purple hairstreak butterflies live in an isolated damp meadow and the larvae only feed on a type of mountain clover that grows in the meadow, what would happen if a fungus caused the clover plants to die off?
The butterflies would increase in population
The larvae would switch to a different type of food
The butterflies would evolve to adapt
The butterflies could become extinct
Animal populations in nature will:
continue to grow indefinitely
never change
be limited by environmental factors
only be limited by genetic mutations
The foxes in a forest primarily feed on a population of mice. A recent disease has caused the mice to die off. What is the best prediction about what will happen to the foxes?
The population of foxes will decline
The population of foxes will not change
The population of foxes will increase
The population of foxes will become extinct
