You get bit by a tick. The tick feeds on your blood and you get Lyme Disease.
What kind of relationship is this?

Give two examples of producers.
Plants, phytoplankton, algae

What 2 biomes would you find an animal with a very thick coat of fur?
Tundra and Taiga

Bees collect nectar and pollen from flowers for food, and in the process they transfer pollen between flowers, allowing the plants to reproduce.
What kind of relationship do the bees and flowers have?
Mutualism
200
Using the food web determine two secondary consumers.
owl and fox
200
What kind of limiting factor is competition?
Density-Dependent

Why are food webs a better representation of an ecosystem compared to a food chain?
Show more of the available feeding relationships within an ecosystem.

What biome is a transitional biome between terrestrial (land) and aquatic ecosystems?
Swamp/Wetlands

Cone snails are slow-moving marine snails, but they hunt using a harpoon-like tooth loaded with venom. When a small fish swims close, the cone snail shoots the harpoon, injects venom, and reels the fish in.
What kind of relationship is this?
Predation
300
Describe the 10% rule.
Only 10% of the energy available in one trophic level is transferred to organisms at the next trophic level.
300
What is a density-dependent limiting factor?
A factor that depends on population size. The size of the population determines the effect the factor has on the population.
300
What kind of organisms are typically decomposers?
Bacteria and Fungi
400
Explain why a saguaro cactus survives so well it the desert.
It's adaptations allow the saguaro to store water and reduce water loss to survive in the hot, dry desert conditions.

Burrowing owls often seek shelter in abandoned prairie dog burrows.
What kind of relationship do the owls and prairie dogs have?
Commensalism
400
If the producer has 300,00 kJ of energy, how much energy do the tertiary consumers have?
300 kJ
400
What is a density-independent limiting factor?
A factor that effects all populations the same way regardless of size.
400
What kind of consumer feeds on the remains of plants, animals, and other dead matter?
Detritivores
500
What is a main difference between grasslands and a savanna besides the animals that live there?
Presence of trees (none in grassland)
Savanna is hot year round and grassland has a hot summer with cold winters
500
Why is competition a -/- relationship?
Both organisms are expending energy to compete for the same resource

Explain how the unicornfish can be a primary and secondary consumer.
It is a primary consumer when it eats phytoplankton (which is a producer) and a secondary consumer when it eats zooplankton (which is a primary consumer)
500
What kind of factor is deforestation? Why?
Density-Independent because it effects the habitat the animals live in creating less resources for the entire population regardless of size.
500
What does the pyramid indicate about the population?
Lots of babies are born, but few survive into adulthood and/or old age.
