Ecological Roles
What is a niche?
This step of the water cycle is what eventually forms acid rain where carbon dioxide mixes with evaporated rain water.
What is condensation?
This is a term used when a species no longer exists
What is an extinction?
This factor is needed for all life to survive on earth.
What is water?
Pakicetus evolved to become this modern large mammal
What is the whale?
This refers to an organism that has no environmental niche in a new ecosystem it is introduced to.
What is a non-native species?
This potent greenhouse gas is the one the primarily makes up cow farts/burps contributing to climate change.
What is Methane?
Some special organisms (like certain species of bacteria) can change nitrogen in the soil into usuable sources by plants. This process is called this.
This term refers to the maximum amount of individuals an ecosystem can hold.
What is a carrying capacity?
This term refers to farms that are on a massive scale producing thousands of livestock for resources.
What are factory farms?
This term refers to two organisms trying to dominate a resource over another for survival.
What is competition?
Pollution uptake in environments, is causing organisms to become this status, prior to being completely wiped out.
What is endangered?
What are calories?
This variable can be a large contributor to species disease uptake/prevention?
What is space/proximity to others?
Secondary succession has this element that makes it occur faster than primary succession.
What is soil?
True/False
Biotic means alive and abiotic means dead
False. Biotic means living and abiotic means nonliving
Humans primary source of energy, to power our lives, comes through the combustion of this substance.
What are fossil fuels?
Primary producers make up the base trophic level (base of the pyramid) as they produce their own food through this process.
What is photosynthesis?
This variable directly impacts organisms ability to reproduce.
What is a mate availability?
This type of interaction helps break down dead material into nutrients that can be used by other organisms.
What are decomposers?
This interaction is when one organism benefits while the other has no negative or positive effect.
What is commensalism?
This term refers to how pollutants accumulated inside organisms will have a higher concentration for organisms higher in trophic levels (top of the ecosystem pyramid).
What is Biomagnification?
If all the producers in an ecosystem disappeared, this group would be affected first.
What are primary consumers?
A pond receives fertilizer runoff from nearby farms. Soon after, algae populations explode, fish begin to die, and oxygen levels drop. Which ecological variable changed first and started this chain of events?
What is the nutrient level in the water?
A forest fire destroys much of a forest. Ten years later, grasses, shrubs, and young trees have returned. What ecological process is taking place?
What is ecological succession?
