What is a food web?
Feeding relationships that are possible in an ecosystem
100
What organism is the producer?
Grass

Can disturbance be beneficial to the environment? Give an example
Yes, fires and natural disasters
100
Nitrogen gas makes up what percent of the air we breathe?
78%

What is the difference between Pioneer species in primary and secondary sucession.
In primary sucession pioneer speies are lichens and mosses.
In secondary pioneer species are grassesand bushes.

What is a consumer?
Organism that eats other organisms, or organic matter instead of producing its own nutrients
200
A food chain is a sequence in which ___________ is transfered from one organism to the next
Energy

What is the job of lichens in ecological sucession?
Process of breking down rocks to form soil.
200
What is detritus?
Waste or debris
200
What is the difference between Primary and Secondary sucession?
Primary starts with no life/ bare rock. Secondary had life before the disturbance.
300
What is climax community?
Populations of plants or animals remain stable and exist in balance with each other and their environment
300
What organism is the secondary consumer?
Snake
300
True or False?
Each new community that arises often makes it harder for the previous commuity to survive
True
300
Why is evaporated water so clean?
The water is warmed by the sun therefore impurities are left behind
300
What is the difference between the phosphorus cycle from other biogeochemical cycles?
The atmosphere is not important in the transfer of phosphorus instead its usually through the form of a solid.
400
What are pioneer species?
Species that first colonize a barren environment or an ecosystem that has been destroyed

A ___________ ___________ is the final, stable community in equilibrium with the environment.
Climax Community

How does nitrogen return to the atmosphere?
Through plants and animals decomposing

What is the difference between a food web and a food chain?
Food web- Feeding reationships in a whole ecosystem
Food Chain- Shows transfer of energy from one organism to the next
500
What is cellular respiration?
The process of breaking down food to yeild energy
500
What happens after an organism dies in a food chain?
Decomposers break it down

What is the difference between autotrophs and heterotrophs?
Autotrophs- Make their own food through photosynthesis to get energy
Heterotrophs- Eat other organisms to get energy
