Potpourri
100
The ultimate source of energy for the biosphere
What is light energy
100
An ecologist would expect to find this type of organism to be the most numerous in an ecosystem.
What are producers?
100
This type of growth has unlimited resources.
What is exponential growth?
100
These organisms have no nuclei or other membrane-bound organelles.
What are bacteria?
100
In this type of symbiosis, both organisms benefit.
What is mutualism?
200
This is what eventually happens to most of the energy that enters a food web.
What is heat energy?
200
This is what an herbivore eats.
What are producers/plants?
200
The carrying capacity limits this.
What is population size?
200
Organisms at this level of classification are the most similar.
What are species?
200
Plants that grow on the branches of other trees are called this.
What are epiphytes?
300
Each step in a food chain is called this.
What are trophic levels?
300
This is the direction that an arrow should point in a food web.
What is an arrow pointing to the organism being eaten?
300
A graph of logistic growth is this shape.
What is an "S" shape?
300
All the organisms in this kingdom can photosynthesize.
What is the kingdom Plantae/Plants?
300
This term refers to the increasing concentration of chemicals (like DDT) as you move up the food chain.
What is biomagnification?
400
This pyramid represents the amount of living organic matter at each trophic level.
What is a biomass pyramid?
400
When these organisms disappear, the entire food web is affected in significant ways.
What are keystone species?
400
This type of growth depletes resources.
What is exponential growth?
400
This category/level includes the greatest number of different types of organisms.
What are kingdoms?
400
This term means maintaining an internal set of conditions.
What is homeostasis?
500
The most energy is available when humans eat this type of diet.
What is a plant-based diet?
500
These organisms eat both meat and plants.
What are omnivores?
500
You can tell the carrying capacity by looking at this graph.
What is logistic growth?
500
This is the order of organism classification from largest group to smallest group.
What is Kingdom, Phylum (Division), Class, Order, Family, Genus, Species?
500
These organisms come from other areas and increase in number, causing harm to the environment as well as expense to humans.
What are invasive species?
