Symbiosis and Succession
100
This is the ultimate image source of food chains qand food webs.
What is the Sun?
100
This process occurs in the chloroplast of the cell.
What is photosynthesis?
100
This is a factor that limits or slows population growth.
What are Limiting Factors?
100
This is described as an organism's role that they play in their ecosystem (job).
What is their niche.
100
This is how water from plants re-enters the atmosphere.
What is transpiration?
100
This symbiotic relationship is when one organism benefits and one is hurt or harmed.
What is parasitism?
200
A single path of energy transfer.
What are food chains?
200
These are the two products (outputs) of photosynthesis.
What are glucose and oxygen?
200
The maximum number of individuals in a species that a population can support.
What is carrying capacity?
200
These are harmful or toxic substances in the environment.
What is pollution?
200
These two processes are responsible for taking in carbon from the atmosphere and releasing it back.
What are photosynthesis and cellular respiration?
200
This symbiotic relationship is when both organisms benefit.
What is mutualism?
300
An organism that eats the producers and nothing else.
What are herbivores or primary consumers?
300
This cell organelle is where cellular respiration takes place.
What is the mitochondria?
300
Population will have this kind of growth when resources are unlimited.
What is exponential growth?
300
These are non-native species that are taken from their native environment and brought to a new environment and outcompete native species.
What are invasive species?
300
This organism plays the biggest role in the nitrogen cycle.
What are bacteria?
300
Barnacles attach to whales and get a free ride and more food. Whales are unaffected by this. Name this type of symbiotic relationship.
What is commensalism?
400
An organism that breaks down and draws nutrients from dead matter.
What are decomposers?
400
This is the cellular energy molecule; also produced by the mitochondria.
What is ATP?
400
This population growth type is when it slows or stops following exponential growth.
What is logistic growth?
400
This describes populations shifting from rural areas to urban areas.
What is urbanization?
400
This refers to when bacteria turn nitrogen from atmospheric nitrogen (N2) into nitrogen we can use (NH3).
What is nitrifying or nitrogen fixation?
400
This type of ecological succession begins with no soil.
What is primary succession?
500
This organism eats secondary consumers and has no natural predators.
What is an apex predator?
500
These are the three products (outputs) of cellular respiration.
What are water, ATP (energy), and carbon dioxide (CO2)?
500
Human activities and natural disasters (e.g. hurricanes, tornadoes) are examples of these type of limiting factors.
What are density independent factors?
500
This term refers to planting one crop in a large field. This also leads to less biodiversity.
What is monoculture?
500
This occurs when nitrogen-containing fertilizers runoff into water bodies.
What is eutrophication or algae blooms?
500
This type of succession begins with soil still intact.
What is secondary succession?
600
This is the amount of energy passed between levels of the food chain.
What is 10%?
600
This green pigment in plant leaves captures sunlight.
What is chlorophyll?
600
Disease, competition, and parasites are all examples of these type limiting factors.
What are density dependent factors?
600
These are the five types of pollution.
What are water, air, soil, noise, and light pollution?
600
This could occur if there's too little carbon in the atmosphere.
What is global cooling or an ice age?
600
These are the first organisms to appear in succession (e.g. lichen and moss).
What are pioneer species?
