Ecology Fun
List 2 Biotic factors from the aquarium.
Varied.
What is an herbivore
an animal that eats only plants OR a primary consumer
Give one example of an autotroph and one example of a heterotroph.
Autotroph: Plants
Heterotroph: Animals, insects, bacteria, fungi
What is the first stage of primary succession?
Give an example of a parasite.
Mosquito, tick, etc
Which way do arrows go in a food web?
prey---> predator
An organism that can produce its own food
An organism that can produce its own food autotroph
Draw a food chain
Grass
Rabbit eats grass
Raccoon eats rabbit
Wolf eats raccoon
Grass --> Rabbit --> Raccoon --> Wolf
Do plants or animals come first in succession?
plants
Name the relationship where both organisms benefit.
Mutualism
If a tertiary consumer is removed from an ecosystem, what would happen to the ecosystem?
ALL species affected, describe.
What is the bottom trophic level of an OCEAN food web?
Protists (algae and phytoplankton)
Bush --> Deer --> Fox --> Coyote
What is the tertiary consumer
Coyote
Compare and contrast terrestrial and aquatic succession.
What is an ecological relationship where BOTH organisms are harmed and why?
Competition+ good explanation
How much energy is lost between trophic levels? Where does it go?
90%, heat.
Only one species benefits without harming or benefitting the other.
commensalism
bush --> deer --> Fox --> coyote
If the deer passes 13,000 kCal of energy to the fox, how many kCal will the coyote gain from the fox?
1300
Which is faster, succession or evolution? How do you know?
Succession usually. Hundreds vs. millions of years.
Which ecological relationship is occurring here? Remoras attach onto dugongs to collect their stool without consent.
Parasitism
What is the trophic level a baleen whale fills? Why?
Calculate the volume of water when the mass is 90 kg and the density is 5 kg/L
18 L
Bush --> Deer --> Fox --> Coyote
Place this food chain in an energy pyramid. Label the consumers and producer.
Draw on board
Give the order of secondary successional stages from start to finish.
grasses--> primary consumers---> bushes----> secondary consumer---> trees---> tertiary consumers
Which relationship do many scientists think is not real and why?
Commensalism, because other creatures can be harmed or helped in ways we don't know.
