Photosynthesis

Two species both benefit - like the honey badger finding food and the honey guide bird having access to it. What is the name of this type of relationship?
Mutualism
100
Which type of species can survive in more habitats - specialists or generalists?
Generalists

What is the most likely limiting factor in the desert biome?
Water

Provide 2 examples of secondary consumers
Answers will Vary: Examples: Mountain Lion, Bears, Tigers

A remora travels on the back of a shark to gain food and the shark does not notice. What is the name of this type of relationship.
Commensalism (Or mutualism if you refer to the clean up of the shark)

Draw a picture that demonstrates biodiversity
Pictures may vary

Cold temperatures are likely a limiting factor in this biome
Arctic/Tundra
300
Would you expect to have more primary or secondary consumers?
Primary consumers because Secondary Consumers consume Primary Consumers.
300
You discover two species that both negatively affect each other. Does this fit the definition of a symbiotic relationship? Why or why not
No. Symbiotic relationships require at least one animal to be receiving benefit.
300
What are the two requirements for something to be an invasive species?
1. Its not native to the ecosystem where it is found
2. It causes harm to the environment, economy, or human health.

One of these pictures shows limited biodiversity. Which one? Explain.
Coral reef because there are more biotic factors.
400
What is the niche filled by decomposers?
The breaking down of all dead organisms

There is a very high population of wolves, what do you expect to happen to the population of deer in the next season?
Answers will vary: Example Response Deer Population to drop drastically due to the increase of wolves.

Which type of variable goes on the x-axis of a graph?
A. Dependent
B. Independent
C. Controlled
B. Independent

Provide an example of where predators would be the main limiting factor
An example where predators are the main limiting factor is a population of Snowshoe Hare in northern forests.
The number of hares is often controlled by predators such as the Canada Lynx. When lynx populations increase, they eat more hares, causing the hare population to decrease. In this case, predation is the main limiting factor because it directly affects how many hares survive.
